Logging in to the CLI via a Linux or Solaris host computer

Logging in to the CLI via a Linux or Solaris host computerConnect to the Memory Array using the kermit application. Save the kermit parameter settings in a .kermrc file so that you do not need to type them each time you connect. Choose another terminal emulation application, such as tip, if your system does not have kermit. The Violin Utilities package for Linux and OpenSolaris include Violins version of kermit called vtkermit.

Note: Place the .kermrc file in your home directory so that the kermit application recognizes it; otherwise, use the -y option followed by the location and file name of the configuration file. To connect to the Memory Array CLI through the serial connection: 1. Log into the host computer as root. At the host computers command line prompt, type: # kermit or # vtkermit 2. Specify the line of the kermit connection. At the kermit prompt, type: C-Kermit> set line /dev/ttyS0

Changing the Default System SettingsTable 1.1, System Defaults,on page 21 list the system configuration default values. When you initially log into the Memory Array through the serial interface, change the following default configuration parameters for security and ease of use. Hostname See Changing the hostname. IP address Gateway Address Netmask Change the network address information to your customer location scheme to prevent problems connecting to the Memory Array. See Changing the default IP address, netmask, and gateway on page 26. Password See Setting the admin password on page 53. To reboot back to the factory default settings, see Rebooting to the factory defaults on page 77.

Changing the hostnameTo access the system CLI, specify the new hostname instead of the IP address in the telnet session. To change the systems hostname from the default setting: 1. Log into the Memory Array. 2. Navigate to the system context level. At the root prompt, type: context system 3. At the system command prompt, type: set name Where: Specifies the hostname of the system.

Note: Depending on your network, you may need to modify the DNS setting to telnet to the Memory Array via the hostname. Changing the hostname ensures that you are connecting to the intended Memory Array if there are multiple Memory Arrays on the network. See Configuring the DNS name on page 30.


25


Changing the default IP address, netmask, and gatewayThe IP address, netmask and gateway are initially set to default values. Change these values to valid addresses within your network to access the system CLI.

Note: When you change the IP address of the system, you will be logged off. Log in again using the new IP address. To change the systems IP address, netmask, and gateway from the default values: 1. Log into the Memory Array.

Note: Use kermit or vtkermit, instead of telnet, to change the IP address in case the IP address is set incorrectly. 2. Navigate to the Ethernet interface context level. At the root prompt, type: context chassis controller ethernet 0 3. At the Ethernet interface context prompt, type: set ip-address [::] Where::

Specifies the IP address of the system. Specifies the netmask of the system. Specifies the gateway address of the system.


26

Assigning the IP Address

Assigning the IP AddressThe Memory Array supports assigning IP addresses either statically or through DHCP. The static assignment Address, Netmask, and Gateway default values are listed in Table 1.3. By default, DHCP is disabled. For convenience, the Violin Ethernet port supports automatic medium-dependent interface crossover (Auto-MDIX). With this, you can connect the Ethernet port on the system to a computer's Ethernet port, such as a laptop, for provisioning before connecting the system to a network switch. You can switch between using DHCP and static addressing. When switching from DHCP to static addressing, the Memory Array selects the default address values if new values have not been pre-provisioned in the CLI. Alternatively, an IP address can be assigned while DHCP is enabled. That IP address is used automatically when switching from DHCP to static IP address assignment (DHCP is disabled).

Note: Manually configure the IP address of the Memory Array as a static IP address in the DHCP configuration file. If it is automatically assigned, then there is a risk of the system being assigned a different IP address upon a reboot.

Retrieving the Violin Memory Arrays MAC addressThe MAC address of the appliances Ethernet port can be found on the back of the system or in the system attribute files. To retrieve the device MAC address and serial number: From the CLI prompt, type show chassis controller ethernet 0 Log into the host computer as root and type: vinfo To add the Memory Array MAC address to the DHCP server, see your DHCP server documentation.

Setting pre-provisioned IP configuration informationWhile DHCP is enabled, you can pre-provision the following IP-related information: IP address Netmask Gateway See Changing the default IP address, netmask, and gateway on page 26. Set these values before disabling DHCP on the Memory Array so that you can connect to the Memory Array at the IP address that you pre-provisioned upon disabling the DHCP option. 1. Log into the CLI via a serial connection or the Ethernet interface. 2. Manually set the IP address, and optionally, the netmask and gateway address. Navigate to the Ethernet 0 context level and at the root prompt, type: context chassis controller ethernet 0 3. Change the IP address configuration values. At the Ethernet 0 context prompt, type: set ip-address [:[:]] Where:


27

Assigning the IP Address Manually specifies the systems IP address. Optional parameter. Manually specifies the systems netmask. Optional parameter. Manually specifies the systems gateway address.

4. Disable DHCP. DHCP will then use the pre-provisioned values that you assigned in step 3. At the Ethernet 0 context prompt, type: set dhcp disable Where:disable Disables using DHCP to automatically set the systems IP address and resets the values to the default values: IP Address192.168.1.2 Netmask255.255.255.0 GatewayUndefined

5. (Optional) To commit the changes made to DHCP and save the information across a system power cycle, move to the System context level by typing: save system config

Configuring Domain Name System (DNS)

Configuring Domain Name System (DNS)When configuring DNS on the Memory Array, you have two available modes: 1. Automatic DNS configuration 2. Manual DNS configuration The Memory Array also has the option of pre-provisioning the DNS information to use when you change your system from automatic DNS configuration to manual. If the DNS configuration is currently in automatic mode, then the current automatically provisioned DNS name and search information is considered to be the provisioned value that will be used when the mode is set to manual. By default, DNS configuration is done automatically when Dynamic Host Configuration Protocol (DHCP) is enabled and connected to a DHCP server that supports specifying the DNS name. If DHCP is disabled, then the DNS mode is automatically changed to manual.

Note: Pre-provision the DNS configuration information before disabling DHCP. Disabling DHCP forces the DNS mode to change to manual and uses default values, making the system unreachable.

Configuring the DNS nameWhen in automatic DNS mode and you set the IP address of the DNS name server, you are pre-provisioning the value. It will not be used until you change the DNS mode to manual. You can configure the DNS name servers IP address at any time. To specify the IP address of the DNS name server of the Memory Array: 1. Log into the CLI via a serial connection or the Ethernet interface. 2. Navigate to the Ethernet 0 context level. At the root prompt, type: context chassis controller ethernet 0 3. At the Ethernet 0 context prompt, type: set dns-nameserver Where: Specifies the IP address of the DNS name server.

Configuring the DNS search domain nameWhen in automatic DNS mode and you set the DNS search domain name, you are pre-provisioning the value. It will not be used until you change the DNS mode to manual. You can configure the DNS search domain name at any time. To specify the search domain name of the Memory Array: 1. Log into the CLI via a serial connection or the Ethernet interface. 2. Navigate to the Ethernet 0 context level. At the root prompt, type: context chassis controller ethernet 0 3. At the Ethernet 0 context prompt, type: set dns-search Where: Specifies the search domain name.

In Example 1.3, the DNS name server IP address and the DNS search domain values have been preprovisioned.Example 1.3 Configuring the DNS Search Domain Name chassis controller ethernet 0> show dhcp enabled ip-address 10.10.0.126 netmask 255.255.255.0 gateway 10.10.0.1 mac-address 00:1B:97:00:00:06 dns-config automatic dns-nameserver 10.10.0.2 dns-search violintech.net prov-dns-nameserver 10.10.0.55 prov-dns-search hi-octane-prod.net

Displaying the DNS mode and pre-provisioned informationDisplay the current DNS mode and various pre-provisioned DNS information on the Memory Array. 1. Log into the CLI via a serial connection or the Ethernet interface. 2. Navigate to the Ethernet 0 context level. At the root prompt, type: context chassis controller ethernet 0 3. At the Ethernet 0 context prompt, type: show If DNS is currently in automatic mode, then the status for dns-config displays automatic. In Example 1.4, the DNS name server IP address and the DNS search domain values have been pre-provisioned.Example 1.4 Displaying the DNS Mode and Pre-Provisioned Information chassis controller ethernet 0> show dhcp enabled ip-address 10.10.0.126 netmask 255.255.255.0 gateway 10.10.0.1 mac-address 00:1B:97:00:00:06 dns-config automatic dns-nameserver 10.10.0.2 dns-search violintech.net prov-dns-nameserver 10.10.0.55 prov-dns-search violintech-prod.net

Setting the DNS ModeSet the Memory Array to automatically configure the DNS name server and search domain or manually. Preprovision the IP address of the name server and the search domain name while the DNS mode is set to automatic. Change the mode to manual to use the pre-provisioned values. To set the DNS mode: 1. Log into the CLI via a serial connection or the Ethernet interface. 2. Navigate to the Ethernet 0 context level. At the root prompt, type: context chassis controller ethernet 0 3. At the Ethernet 0 context prompt, type: set dns-config { manual | auto } Where:manual Specifies the DNS mode to manually set the DNS name server IP address and search domain. automatic Specifies the DNS mode to automatically set the DNS name server IP address and search domain.

Verifying the Ethernet Connection

Verifying the Ethernet ConnectionThe Ethernet interface can also be used to connect to the CLI of the Memory Array. This section explains how to verify that the Ethernet connection is operating properly. To verify the Ethernet connection: 1. Log in to the host computer as root. 2. To retrieve the IP address of the Memory Array, do one of the following: a. Via the serial port connection to the Memory Array, log into the CLI (See Logging into the CLI via the Serial Interface on page 22) and type this command at the command prompt: show chassis controller ethernet 0 which returns the systems IP address and other Ethernet settings. b. Connect to your DHCP server that assigned the IP address to your Memory Array and retrieve the IP address from that location. 3. Open a terminal or command line window and, at the command prompt, type: $ ping | Where: Specifies the IP address assigned to the Memory Array. If using DHCP and the Memory Array is registered on the DNS, specifies the name of the Memory Array.

If the host computer can connect to the Memory Array, then it will return a successful ping message. If it cannot connect to the Memory Array, then a failed ping message is returned. You can also connect to the system via the Ethernet port using telnet or ssh as described in Connecting to the CLI on page 38. If you are using DHCP and DNS, you can use the systems name instead of the IP address to connect through the network.

Displaying and Setting System Log (Syslog) Options

Displaying and Setting System Log (Syslog) OptionsThe Memory Array logs system messages that can be sent to a host running a syslog server for long term storage. If numerous messages are generated, then the log buffer may fill up and, since it is a circular buffer, overwrite older messages.The message level mapping between the message level definitions and your hosts syslog message level definitions are listed in Table 1.4. Display the man page for syslog.conf on the host for more information.Table 1.4 Definition Mappings Memory Array DEBUG INFO WARNING ERROR FATAL debug info warn emerg emerg Syslog

When syslog messages are received on the host, they are written to whatever logging device is configured. Frequently, this means that warn messages are written to a file, such as /var/log/messages or /var/adm/messages, and emerg level messages are written to all root consoles. On the Memory Array, messages that are set to the WARNING, ERROR or FATAL level are sent to the host.

Displaying the Configured IP address of the syslog hostTo display the IP address of the host to which the system log messages will be sent: 1. Log into the Memory Array. 2. Navigate to the syslog context level. At the root prompt, type: context system logging syslog 3. At the syslog context prompt, type: show host The command displays information similar to Example 1.5.Example 1.5 Displaying the IP Address of the syslog host.

system logging syslog> show host host 192.37.87.4


34


Setting the IP address for the syslog hostSend system log messages to a host attached to the Memory Array via the Ethernet port. This host must have syslog configured correctly. See your hosts syslog documentation for instructions.

Note: From the CLI prompt, type the ping command to verify the connection between the Memory Array and the remote syslog host. To set the IP address of the host to which the system log messages will be sent: 1. Log into the Memory Array. 2. Navigate to the syslog context level. At the root prompt, type: context system logging syslog 3. At the syslog context prompt, type: set host Where: Specifies the IP address of the host to which the system log messages will be sent.

4. To commit the change made to the IP address, from the System context level command prompt, type: save config

Tip: Or, from the syslog context level, type: top save config or save system config

Determining the status of the system log serviceDisplay the status of the service that sends the system log messages to a host. 1. Log into the Memory Array. 2. Navigate to the syslog context level. At the root prompt, type: context system logging syslog 3. At the syslog context prompt, type: show service The command displays information similar to Example 1.6.Example 1.6 Determining the Status of the System Log Service system logging syslog> show service service on
