Terminology

This document uses the following terms:

host A computer that is or will be connected to a CLARiiON storagesystem. This computer is called either a management station or aserver, depending on how it is or will be connected to the storagesystem.

management station A host from which you manage CLARiiON storage systems. Itmust be on the same LAN as the storage-system managementports. A management host may also be a server.

server A host that is already or will be connected through a switch tothe Fibre Channel ports on a CLARiiON storage system. Amanagement host may also be a server.

new server A server that is not already connected to or set up for a CLARiiONstorage system.

existing HBA The host bus adapter (HBA) that is already installed in a server.

new HBA The HBA that was not already installed in the server.

existing storage system A storage system that is already connected to a server andconfigured for storage.

field-replaceable unit(FRU)

A storage-system component that you can add to your storagesystem or replace in your storage system at your site. Examplesof FRUs are disks, power supplies, memory cards, and powersupplies.

storage processor (SP) A printed-circuit board with processors, memory modules, andcontrol logic that manages the I/O between the server and thedisk modules.

LUN A grouping of physical disk partitions into one span of disk storagespace. Each LUN you create is distributed equally across thedisks in the RAID group. A LUN looks like an individual disk tothe server’s operating system.

RAID group A set of disks with the same capacity and RAID type on whichyou create one of more LUNs.

2 Installing a CX3-40c Storage System in a Fibre Channel Switch Configuration with a Windows Server

storage group A group of one or more LUNs that you connect to a serverto provide the server access to the LUNs. Only the serversconnected to a storage group can access the LUNs in the storagegroup.

A CX3-series storage system has two SPs, so it is called a dual-SP system.

Installing PowerPath on a server

Two versions of PowerPath® are available for your server — PowerPathSE or full PowerPath.

PowerPath SEPowerPath SE provides basic failover features for storage-systemconfigurations in which the server has only one HBA connected to astorage system through a switch and exactly one path zoned to each SPin the storage system. Basic failover protects against SP and back-endstorage-system failures, and supports non-disruptive (online) upgradesof storage-system software. It does not protect against HBA or switchfabric failovers. PowerPath SE ships in the utility kit for your serverand does not require a license.

PowerPathPowerPath provides full failover for any storage-system configuration.Full failover manages the I/O paths between the server and the storagesystem. It protects against back-end storage-system failures, HBAfailovers, and switch fabric failovers, and supports non-disruptive(online) upgrades of storage-system software. PowerPath also providesI/O load balancing.

PowerPath 4.6 does not support Windows 2000.


Before you start

To complete this procedure, you will need to:

❑ Locate the PowerPath for Windows CD in the utility kit (PowerPathSE) or the PowerPath kit.

❑ If you are installing full PowerPath (not PowerPath SE), locate thePowerPath license key card in the PowerPath kit.

Installing the Navisphere Server Utility or Navisphere Host Agent

You must install the Navisphere Server Utility or Navisphere HostAgent on each server connected to the storage system. During theinstallation, if you do not disable the Registration Service option (itis enabled by default), the server utility automatically registers theserver’s HBAs with the storage system.

Determining whether to install the host agent or server utility

Depending on your application needs, you can install the host agent,server utility, or both on an attached server.

If you want to install both applications, you must install revision6.22.20 or later of the server utility either before or after you install thehost agent. The registration feature of the server utility will be disabledand the host agent will be used to register the server’s HBAs to thestorage system.

Note: Prior to revision 6.22.20 of the server utility, you could not install the hostagent and server utility on the same server. However, you could install themon different servers that are connected to the same storage system.

If you do not want to install both applications, but want to use someof the features available in the server utility, you can run the serverutility from the server support CD.

Table 1 describes the differences between the host agent and the serverutility on a server attached to a storage system.

Important: Depending on the revision of the server utility, some of the featureslisted in Table 1 may not be available.


Table 1 Differences between the host agent and the server utility

Function Host agent Server utility

Pushes LUN mappingand OS information to thestorage system.

Yes – LUN mapping information isdisplayed in the Manager UI next tothe LUN icon or with the CLI usingthe -lunmapinfo command.

CX3-series and CX-series storage systemsNo – LUN mapping information is not sent to the storage system. Onlythe server’s name, ID, and IP address are sent to the storage system.Note: The text Manually Registered appears next to the hostnameicon in the Manager UI indicating that the host agent was not used toregister this server.

Runs automatically tosend information to thestorage system.

Yes – No user interaction isrequired.

CX3-series and CX-series storage systemsYes – You can control whether server information is auto-matically sent to the storage system by enabling or disabling theregistration service feature (see note at the end of the table). Thisfeature is automatically enabled during the installation of the serverutility, but you can stop the service at anytime through the servicesoption in the Microsoft user interface. Note that only the server’sname, ID, and IP address are sent to the storage system; LUNmapping information is not sent.

Provides high-availability(HA) validation

No – You can run the server utility’sHA validation feature from the CDwithout having to install the serverutility.

CX3-series and CX-series storage systemsYes – The HA validation feature verifies that failover soft-ware is installed on the server and that working paths exist betweenthe server and each SP in the storage system.

Requires networkconnectivity to the storagesystem.

Yes – Network connectivity allowsLUN mapping information to beavailable to the storage system.

CX3-series and CX-series storage systemsNo – LUN mapping information is not sent to the storagesystem. Note that if you are using the server utility to upload a highavailability report to the storage system, you must have networkconnectivity.


Function Host agent Server utility

Requires installation. Yes – You must install the hostagent on the server.

CX3-series and CX-series storage systemsNo – You can run the server utility from the CD. However,we recommend that you install it on the server. You must install theutility to use the registration service feature (described above).

Note: If you install both the host agent and revision 6.22.20 or later of the server utility (the order of which does not matter), the serverutility’s registration service feature will not be installed. Prior to revision 6.22.20 of the server utility, you could not install the host agentand server utility on the same server.

Before you start

To complete this procedure, you need the server support CD thatshipped with the storage system.

11. Click Done to exit the installation wizard.

12. If you have a multihomed host (multiple NIC cards installed onthe host), create an agentID.txt file to ensure that the agent findsthe correct NIC card.


Note: A multihomed host machine has multiple IP addresses connected tonetworks; it is physically connected to multiple data links that can be on thesame or different networks. When you install Navisphere Host Agent on amultihomed host, the host agent, by default, binds to the first NIC in thehost. If your host is multihomed, for the host agent to successfully registerwith the desired CLARiiON storage system, you need to configure the hostagent to bind to a specific NIC. You do this by setting up an agentID.txt file.

a. Using a text editor that does not add special formatting, createa file named agentID.txt (case sensitive) in the directoryC:/ProgramFiles/EMC/Navisphere Agent.

b. Add the following two separate lines to the agentID.txt file,with no special formatting:

First line: Fullyqualified hostname of the host

Second line: IP address of the HBA/NIC port that you

want Navisphere agent to use

For example, if your host is named host28 on the domainmydomain.com and your host contains two HBAs/NICs,HBA1/NIC1 with IP address 192.111.222.2 and HBA2/NIC2with IP address 192.111.222.3, and you want the host agent touse NIC 2, you would configure agentID.txt as follows:

host28.mydomain.com192.111.222.3

Note: The agentID.txt file should contain only these two lines, withoutany formatting. The first line should contain the hostname and thesecond line should contain the IP address of the HBA/NIC port asdescribed above. Both lines should end with a carriage return. As aresult, the cursor will be on a third line but this line should not containany text.

c. Save the agentID.txt file.

d. If a HostIdFile.txt file is present in the C:/Program-Files/EMC/Navisphere Agent directory, delete or rename it.


e. Restart the host agent.

f. Once the host agent has restarted, verify that the host agent isusing the correct IP address that is entered in the agentID.txtfile by doing one of the following:

In Navisphere Manager, verify that the host IP address is thesame as the IP address that you entered in the agentID.txtfile. If the address is the same, the agentID.txt file isconfigured correctly.

View the new HostIdFile.txt file. You should see the IPaddress that is entered in the agentID.txt file.

13. If you installed the host agent from the CD, close the server supportmenu by selecting Main Menu and then Exit. You can now removethe CD from the server’s CD drive.

14. Verify that Navisphere Agent is installed using the Add/RemovePrograms dialog box.

Installing the Navisphere Server Utility on a Windows server

EMC recommends that you install the most recent version of theNavisphere Server Utility software that is appropriate for yourconfiguration. You can download the most recent version from eitherthe software download page on the Powerlink website (CX3–series andCX-series) or on the support website (AX-series storage systems). Youcan also install the software from the server support CD (any storagesystem); however, the CD may not contain the most recent version foryour configuration.

Important: If you are running PowerPath 4.6 or later, you must install version6.22.20 or later of the Navisphere Server Utility.


2. To download the software for CX3–series or CX-series storagesystems, do the following:

a. On the Powerlink website, select Support > SoftwareDownloads and Licensing and navigate to the NavisphereServer Utility download section, which may be in eitherthe CLARiiON Navisphere Server Utility section or theCLARiiON Navisphere Manager section.



b. Select the appropriate Navisphere Server Utility version todownload and select the option to save the software to yourserver.

c. In the directory where you saved the software, double-click theexecutable file to start the installation wizard.

3. To install the software from the server support CD (any storagesystem), do the following:

Connecting Fibre Channel switches to the storage system and server

Use optical cables to connect switch ports to storage-system FibreChannel data ports (labeled 4 Fibre and 5 Fibre on each SP) and toserver HBA ports.

Applications such as MirrorView™/A, MirrorView/S, or SAN Copy™software may restrict or require the use of certain SP ports. Refer to theapplication documentation for specific cabling information.

Before you start

To complete this procedure, you will need an optical cable for eachswitch port you will use. Specifications for the optical cables thatconnect the switch to the storage system are in the storage system’stechnical specifications in the documentation section of Powerlink.

Handling optical cables

Optical cables are susceptible to damage, so take the followingprecautions when handling them:

Keep the covers on all optical cables until you are ready to insertthem.

Avoid tight bends. If you need to make a 90º bend, do it over 6 to12 inches.

Do not use optical cables to support weight (including their ownunsupported weight if they are long).

Do not pull long runs of cable; instead, lay the cable in place or pullonly a few feet at a time.

Place the cables where no one can step on them or roll equipmentover them.

Cabling the Fibre Channel switch to the storage system (if necessary)

For highest availability with a multiple-HBA server, connect one Fibreport on SP A to one switch and one Fibre port on SP B to anotherswitch port.



Customer-installable switches are easily configured. Some arepreconfigured, to use only ports 0 and 4 for SP connections and onlyports 1-3 and 5-15 for HBA connections. With switches set up in such“hard zones,” you can connect the Fibre ports only to ports 0 and 4 andHBAs only to ports 1–3 and 5–15. For highest availability with oneof these “hard zoned” switches and a multiple-HBA server, connecteither Fibre port on SP A to switch port 0 and either FE port on SPB to switch port 4.

For each Fibre port that you want to connect to the switch:

1. Remove the protective cover from the optical connector on theswitch port that you will use and from one end of the optical cable,and plug the cable into the switch port.

2. Remove the protective covers from the Fibre connector on the SPand from the free end of the optical cable, and plug the cable intothe Fibre connector (Figure 1).

EMC3459

1 Fibre

Figure 1 Connecting optical cables from the switch to the Fibre Channel front-end ports

Cabling the Fibre Channel switch to the server

1. For each switch port that you want to connect to the server:

a. Remove the protective covers from the HBA port connector onthe server and from one end of the optical cable, and plug thecable into the HBA connector.


b. Remove the protective covers from the free end of the opticalcable and from the lowest-numbered unused switch port (forhard–zoned switch ports 1-3 and 5-15), and plug the cable intothe switch port.

For a hard-zoned switch, you must use these ports in order from 1-3,5-15.

2. If the switch is not already powered up, power it up.


Zoning the switches

You must use switch management software to update switch softwareand zone switches that are not hard zoned.

1. Connect the switch management ports to the network from whichyou will manage the switches.

2. If the switches are not running the most recent supported firmwareversion, install this software from the switch vendor’s website.

For information on the supported switch firmware versions, see the E-LabInteroperability Navigator on Powerlink.

3. Locate the zoning wizard CD that shipped with the switch.

4. Using the instructions provided with the CD, run the zoning wizardand select the zone configuration that is applicable to the way thatyou connected the storage-system Fibre ports and the server HBAports to the switch.



Registering the server with the storage system

Run the Navisphere Server Utility or Navisphere Host Agent on eachserver connected to the storage system to register the server’s HBAswith the storage system.

Running the Navisphere Host Agent on a Windows server

1. At the Windows server, log in as the administrator or the equivalent.

2. From the desktop, right-click My Computer and select:Manage > Services and Applications > Services

When the host agent starts it sends the server’s name and IP addressto each storage system connected to the server.

Running the Navisphere Server Utility for Windows

You can run the Navisphere Server Utility for Windows from the server,if you installed the utility on the server, or from the server support CD,which shipped with the storage system.

















Registering the server using the Navisphere Server Utility for Windows

Note: If the host agent is running, stop the host agent service.


1. In the Navisphere Server Utility dialog box, select Register thisserver to all connected storage systems.

The utility automatically scans for all connected storage systemsand lists them under Connected Storage Systems. Locate theWWN of the HBA you just installed. The HBA should appear oncefor every SP port it is connected to.

If the utility is already running, it does not automatically perform a scan,and you must click Rescan.

2. Click Next to register the server with the storage system.

The utility sends the server’s name and WWN of the HBA to eachstorage system. Once the server has storage on the storage system,the utility also sends the device name and volume or file systeminformation for each LUN in the storage system that the server sees.

3. Click Finish to exit the utility.

4. If you stopped the host agent, restart it.

Verifying HBA registration

Use Navisphere Manager to verify if a server’s HBAs are registeredwith the server.

For assistance in resolving any problems, see the troubleshootingflowcharts for the CX3-series storage system on the CLARiiONTools page of the Powerlink website.



Verifying your high-availability configuration

Use the server high-availability feature in the Navisphere ServerUtility to verify the following for each server in a high-availabilityconfiguration with the storage system:

Your Fibre Channel configuration is highly available (that is, eachFibre Channel HBA has at least one active path to each storageprocessor).

Path management software is installed and running on the server.

Before you start

If the Navisphere Server Utility is not installed on the server, locate theserver support CD, which shipped with the storage system.

















Using the server utility to verify your high-availability configuration

1. In the Navisphere Server Utility dialog box, select Verify ServerHigh-Availability to generate a report of the server’s environment.

This option detects if PowerPath or some other failover software,such as DMP, is running. After the verification, the utility generatesa summary report and saves it to the server.

2. Review the generated report to confirm that your serverconfiguration is highly available.

3. If the server configuration is not highly available, make it so beforecontinuing.


Installing CLARalert software

CLARalert® software monitors your storage system’s operation forerror events and automatically notifies your service provider of anyerror events. CLARalert is available from the CLARiiON Tools page onthe Powerlink website. If the CLARiiON Tools page does not containa CLARalert link, your service provider can install the CLARalertsoftware.


CLARalert uses a centralized monitoring environment. In a centralizedmonitoring environment you designate a monitor station to monitorthe events of storage systems you specify. The centralized monitoringenvironment is a monitoring environment option for Event Monitor,which is a feature of the Navisphere Manager application.

During the CLARalert installation, you designate the monitorstation and portal system to configure your centralized monitoringenvironment. The storage system that you designate as a portal systemduring CLARalert installation is automatically added to the list ofmonitored storage systems. You can later add storage systems to yourcentralized monitoring environment using Navisphere Manager. Formore information, see the Navisphere Manager help, which is in theNavisphere Manager UI or the Documentation/White Paper Libraryon the Powerlink website. The Documentation/White Paper Libraryhas the most recent version.





For a new CLARalert installation, the wizard automatically installs the emailnotification service, which sends event notification to your service providervia email (SMTP). CLARalert integrates with WebEx, allowing you to initiatereal-time customer support sessions over the web. See the WebEx EMC SupportCenter at https://emcsupport.webex.com for more information on WebEx.

CLARalert requirements

CLARalert installation and operation requires that TCP ports 80, 443, 25 (SMTPserver) are open. Refer to the EMC CLARalert Release Notes for the most currentCLARalert environment and system requirements.

The CLARalert version must be at or later than the version of FLARE ®Operating Environment (OE) running on each storage system that themonitor station monitors. CLARalert installation requires:

❑ A monitor station, which is a host running a supported Windowsoperating system. For supported versions, refer to the EMCCLARalert Release Notes. The monitor station cannot be a server(host connected to storage-system data ports), and it must be on thesame network as your storage-system management ports.

CLARalert is installed on and runs on the monitor station. Themonitor station must have a static or DHCP reserved IP address.The wizard automatically detects and supplies the IP address forthe monitor station, which is required for CLARalert installation.You can verify the IP address in the wizard and, if required, supplya different one.

❑ A portal system, which is a storage system running the requiredFLARE Operating Environment (OE ) version. For requiredversions, refer to the EMC CLARalert Release Notes.

You must provide the IP address for either SP of the portalsystem during CLARalert installation. You must also supplylogin credentials for the portal system (global manager or globaladministrator) during installation.


https://emcsupport.webex.com

If your CLARalert installation will use email notification, for example, for anew installation, you will need connectivity to an outgoing SMTP server. Youmust provide the IP address for the SMTP server during CLARalert installation.You must also provide your service provider email address (to) and your localemail address (from) for email notification.

If you do not have an existing monitor station — You can create amonitor station by installing CLARalert on a Windows host.

If you have an existing monitor station running CLARalert — You canupgrade CLARalert on the monitor station. The upgraded CLARalertwill use the previously configured method for event notification.

If you have an existing monitor station running event monitor — Youcan install CLARalert on the monitor station.

1. Locate your completed storage-system disk information worksheetso you can refer to it in the steps that follow.

2. If you need additional RAID groups for the server, create one ormore RAID groups.

A RAID group is a set of disks, all with the same capacity and redundancy,on which you create one or more LUNs. A RAID 6 group usually has 6 or12 disks, but can have 4, 8, 10, 14, or 16 disks. RAID 6 groups are supportedon CX3-series storage systems running FLARE OE version 03.26 or higher.A RAID 5 group must include at least three disks, a RAID 3 group mustinclude five or nine disks, and a RAID 1/0 group must include at least twodisks. The storage-system type determines the number of RAID groupsthat it supports.

To create a RAID group — In the Navisphere Manager tree,right-click the icon for the storage system, and click Create RAID


Group. For details on creating RAID groups, use the NavisphereManager help.

The disk modules in slots 0 through 4 of the first DAE (enclosure 0, bus0) provide mirrored boot and recovery capability, and are preconfiguredaccording to their slot assignment before shipment. Do not move a diskmodule in slots 0 through 4 from its assigned slot to another slot. Removeone of these disk modules only if it has failed and you are replacing it witha new module.

3. Create additional LUNs on any additional RAID groups youcreated or on existing RAID groups on which you need additionalLUNs for the server.

To create a LUN — In the Navisphere Manager tree, right-click theicon for the storage system, and click Bind LUNS. For details onbinding a LUN, use the Navisphere Manager help.

4. Create any additional storage groups that you need for the server.

Creating Windows partitions on a basic disk for a Windows server

You can create four primary partitions or one extended partition andthree primary partitions on a basic disk.

If the server is running Windows Server 2003, you can create a 2 TBor larger partition on a basic disk that is a globally unique identifierpartition table (GPT) disk. Windows 2000 does not support GPT disks.

1. In the Disk Management screen, right-click the free space area ofthe basic disk that you want to partition, and click Create Partition.


2. In the Create Partition Wizard, click Next and follow theinstructions that appear on the screen to select a primary orextended partition, specify the partition size, and assign a driveletter or path for the partition.

3. In the Format Partition screen, select Quick Format, and follow theinstructions that appear.

4. If you want a logical drive on an extended partition, create it:

a. Right-click the free space area of the extended partition, andclick Create Logical Drive.

b. In the Create Logical Drive Wizard, click Next and click LogicalDrive.

c. Follow the instructions that appear on the screen to specify thepartition size and assign a drive letter or path for the partition.

d. In the Format Partition screen, select Quick Format, and followthe instructions that appear.

The partition or logical drive is ready for data.

Creating volumes on a dynamic disk for a Windows server

If the server is running Windows Server 2003, you can create a 2 TB orlarger partition on a dynamic disk that is a globally unique identifierpartition table (GPT) disk. Windows 2000 does not support GPT disks.

You can create an unlimited number of volumes on a dynamic disk.

1. In the Disk Management screen, right-click the free space area forthe dynamic disk on which you want to create volumes and clickCreate Volume.

2. In the Create Volume Wizard, click Next and follow the instructionsthat appear on the screen to specify the volume type; then select thedisk and assign a drive letter or path for the volume.

3. In the Format Partition screen, select Quick Format, and follow theinstructions that appear.

The server can now send data to and receive data from the volume.

Saving the PowerPath configuration

Save the server’s PowerPath configuration with the followingPowerPath command: powermt save.


The powermt save command creates the powermt.customconfiguration file.


Sending Windows disk information to the storage system

If the Navisphere Host Agent is installed on the server, start or restart(stop and then start) it to send to the storage system the operatingsystem’s device name and volume or file system information foreach LUN that the server sees. Navisphere Manager displays thisinformation on its LUN Properties — Host page for each LUN.

The Navisphere Server Utility does not send operating system LUN mappinginformation to the storage system.

Stopping the host agent


2. From the desktop, right-click My Computer and select Manage >Services and Applications > Services


3. In the Services pane, right-click Navisphere Agent and select Stop.

4. If asked to confirm your request to stop the agent service, click Yes,and close the Services pane or dialog box.

Starting the host agent


2. From the desktop, right-click My Computer and select Manage.

The Computer Management window opens.

3. Select Services and Applications > Services.


4. In the Services pane, right-click Navisphere Agent and select Start.

5. If you want the host agent to start automatically at system startup:

a. Right-click Navisphere Agent and select Properties.



b. Select the General tab.

c. In Startup Type, select Automatic.

6. Close Computer Management.

The host agent will now start automatically at system startup.

It may take a few minutes for the host agent to start in either of thefollowing situations:

Applications are using the storage system.

The SP event log is large and the host agent configuration file isnot set up.

Verifying that the storage system received the LUN information using NavisphereManager

1. Start Navisphere Manager on the storage system with the LUNs.

2. For each LUN in the storage system that is connected to the server,display its Navisphere Manager LUN Properties — Hosts page:

a. In the Navisphere Manager Storage tree, navigate to the LUNyou want to verify.

b. Right-click the icon for the LUN, and click Properties.

3. Verify that the Properties page displays a physical device andlogical device name for the LUN.


Verifying your failover configuration with PowerPath

Before you store data on LUNs, use the procedure in this section toverify that:

The server can send data to and receive data from the storagesystem.

You can download an I/O simulator (Iometer) for writing data to thestorage system from the following website: http://www.iometer.org/.

PowerPath shows the paths from the server to the LUNs that youexpect for your configuration.

Verifying your failover configuration with PowerPath for a Windows server

1. If you are connected to an existing storage system, stop allapplications that are accessing the storage system and disable userlogins to the server.

2. Launch PowerPath Administrator by double-clicking thePowerPath Monitor on the Windows taskbar.

3. On the left pane (summary pane), click EMC PowerPathAdministrator.

4. Under the server, right-click Disks.

The right (details) pane lists all the LUNs (disks) in each storagesystem connected to the server. Storage ID identifies each storagesystem. For each disk, the Path Status and the Path Metric columnsgive the status of the paths to the disk. When all n paths to a diskare working, the Path Status for the disk is optimal and the PathMetric for the disk is n/n, indicating that n of n paths are working.If only m paths are working, the path metric is m/n.

5. Verify that all n paths to the disks in the storage system are working,that is, their status is optimal and their path metric is n/n.

If all the paths are not working, refer to the troubleshootingflowcharts on the CLARiiON Tools page on the Powerlink website.


http://www.iometer.org/



6. For each HBA connected to the storage system:

a. Start writing data to a LUN.

b. Disconnect the cable from one HBA connected to the storagesystem.

c. After several seconds, look at the Details pane and verify thatone or more of the disks in the storage system have red slashesthrough them, their status is degraded, and their path metric ism/n, where n is the number of paths to the disk and m is thenumber of working paths, which is less than n. For example, ifthe server has 4 paths to a disk in the storage system and 1 pathfails when you disconnect the cable, then n=4 and m=3, so thepath metric is 3/4.

d. Reconnect the cable that you disconnected from the HBA.

e. Right-click the PowerPath Monitor icon on the taskbar, andselect All Tasks and Restore All Devices.

f. After several seconds, look at the details pane and verify thatnone of the disks in the storage system have red slashes throughthem, their status is optimal, and their path metric is n/n.

If any disks do not have optimal status and their path metricis not n/n, refer to the troubleshooting flowcharts on theCLARiiON Tools page on the Powerlink website.

To access the CLARiiON Tools page, use the Navigator drop-downmenu at the top right of the Powerlink home page.

7. Restart any applications that you stopped and re-enable any userlogins to the server that you disabled.
