2 Introduction


General Description

CAUTION: The InfoStation chassis contains NO USER SERVICEABLE parts inside the unit.Refer ALL servicing to qualified personnel!

NOTES: The configuration and use of the InfoStation RAID Controller requires a certainlevel of expertise and experience on the part of the user/integrator. Since thereare many configuration options and variables (ie. host platforms, applications,etc.), only general guidelines will be discussed in this User's Guide.

Refer to the disk manufacturer's documentation for specific information re-garding the disks.

High performance InfoStation 12-bay SCSI-to-Serial ATA and FC-to-Serial ATA RAID enclo-sures are designed to support low-profile Serial ATA (SATA) or Parallel ATA (Ultra ATA/100)drives for RAID applications. The SCSI-to-SATA enclosures (P/Ns S10H108 & S10H112)support dual SCSI Ultra320 host channels and are downward-compatible with earlier SCSIWide Single-Ended or LVD interface technologies (i.e. Ultra2 or Ultra). Daisy-chaining chassisfor extended storage is also possible with optionally available SCSI Ultra320 repeater kits. TheFC-to-SATA enclosures (P/Ns S10K102 & S10K104) support dual Fibre Channel ArbitratedLoops (FC-ALs) with 2Gbps operation.

Each standard 4U rack mount 12-bay RAID InfoStation chassis comes equipped with a RAIDcontroller, (12) removable drive carriers and an open 5.25" half-height device bay. Theseenclosures are constructed of corrosion-resistant steel and each include (2) hot-swappable,redundant 460W power supply modules and (2) hot-swappable, redundant, variable-speedfan modules.

Both the SCSI-to-SATA and FC-to-SATA RAID chassis support RAID levels 0, 1, 0+1, 3, 5, 30,and 50, and is OS independent. Online Capacity Expansion (OCE) and LUN support, up to1GB DDR PC2100 SODIMM cache memory, as well as automatic hot swap, hot spare anddrive rebuild support are all included. An audible alarm on the InfoStation alerts the User tosystem hardware failures and warning conditions. LED indicators at each drive bay provideadditional User feedback for drive activity, drive readiness and drive faults.

The InfoStation also incorporates "Soft Start" circuitry which eliminates in-rush current to eachof the installed drives during spin-up, as well as avoid power arcing during drive insertion.

A User Interface Module on the 12-bay InfoStation provides the User with a visual indicationof chassis configurations and communication statuses, in addition to providing an RS232connection for system environmental monitoring, configuration and control. InfoMon®, adownloadable chassis monitoring utility program, provides the InfoStation with a customizable,web-based monitoring capability via the RS-232 serial connection. InfoMon includes a “CallHome” feature, which enables chassis log information to be conveniently sent to a predeter-mined FTP site for trouble shooting and analysis. InfoMon also provides the User the ability toeasily configure both device and chassis settings with a few clicks of the mouse! Refer toAppendix B for further information on InfoMon.

Introduction 3


The latest versions of the InfoMon utility program and User's Guide can be downloaded (freeof charge) from the StorCase web site (http://www.storcase.com). Contact StorCase forfurther information. Refer to Appendix B for further information on optional InfoStationaccessories.

Using a modular approach supported by redundant features and hot swapping capabilities,the InfoStation will provide continued data availability and allow for ease of maintenance andminimal system down time.

The modular and scalable design of the InfoStation chassis also allows a variety of futureproduct upgrades to be offered. Upgrade modules are anticipated InfoStation options.

RAID Configuration via InfoStation RAID Control Panel

The InfoStation RAID Control Panel may be used to configure the InfoStation RAID controller.

RAID Control Panel

The RAID control panel (Figure 25) allows for exploration of all configuration options. However,the LCD screen can only display limited amounts of information at a time.

To display all information on a larger terminal screen, the RAID Controller can be accessed viaa computer serial port (female DB9-female DB9 cable provided) using either the Monitor Utility(HyperTerminal) or Data Master GUI.

NOTE: The Monitor Utility and the front control panel cannot be used at the same time.When one is active, the other is disabled.

Mode Operation

The SCSI-to-SATA RAID Controller operates in three (3) modes:

• Self-Diagnostic Mode

• Configuration Mode

• Operation Mode

Self-Diagnostic Mode

To ensure flawless operation, the RAID Controller has a built-in self-diagnostic utility. Self-Diagnostic Mode occurs automatically upon power up, or after the RAID Controller has beenreset. During this mode, all components are tested and any potential problems are reported.

The Self-Diagnostic Mode runs three major diagnostic tests. The first diagnostic includestesting the CPU and supporting core logic chips, the internal bus, memory, SCSI controller,SATA controllers, and RS-232 controllers. The second diagnostic tests for the presence ofdisks on each individual disk channel. It also checks the functionality of each disk found. Thefinal diagnostic tests the RAID functionality.

Configuration Mode

NOTE: The RAID Controller should be OFFLINE (disconnected from the host system)when Configuration Mode is running.

Configuration Mode may be selected whenever <ENTER> is pressed during Operation Modeor when the Monitor Utility is invoked from the remote terminal. In Configuration Mode, the useris able to modify the settings of the RAID Controller and perform different functions to thecontroller.

Entering a Password

If the password-check feature is enabled, the user will be prompted to enter a passwordbefore proceeding (the default password is "00000000"). Refer to section "4 PasswordSecurity" for information on how to change the default password.

The user may use the front control panel buttons to enter the password. Use the � and �keys to scroll through the available characters, then press <ENTER> to select the characterand move to the next position. Once all the characters have been entered, press <ENTER>to access the Configuration Mode.



The Main Menu consists of six (6) categories, as shown in Table 5.

NOTE: Make sure that new disk capacity is equal to or larger than the current onlinecapacity.

Select array to be expanded (Array 1-8), then the number of disks in the new array.

To expand disk capacity:

1. Connect new disk.

2. Use Expand Array menu to select the number of disks in the array.

3. Go to the 1.1.4 Slice menu. The new capacity should appear as a new slice. If noslices were created previously, the new capacity will appear as Slice 1.

6.9 Log Event

6.9.1 Erase

This function enables the user to erase the event log.

6.9.2 Statistic



6.9.3 RTC

NOTE: When using the RAID controller for the first time, users will need to set the RTCParameters. Setting the RTC parameters will enable the RTC function on thecontroller. When an event occurs, the Log Event wil then be able to record theevent in real-time.

This function enables the user to adjust real-time clock settings.

Select one of the two functions to do all disks or Disk 1-16 detection.



6.A.1.3 Stop DST

6.A.2 Disk Scrubbing

NOTES: For disk scrubbing to start, the array must be at its optimum. There cannot beany failed member disks or background tasks (such as adding a disk or ex-panding an array).

Once disk scrubbing starts, the user cannot start any other background taskand array cannot be deleted.

This function enables the user to prevent unrecoverable data loss, recover bad blocks, andfix parity errors.

Disk scrubbing provides the following advantages:

1. Disk scrubbing will not prevent normal host access. It will slow down the system'soverall performance however.

2. Disk scrubbing can be started and processed simultaneously for multiple arrays.

6.A.2.1 Overwrite Parity

Select either No (Default) or Yes. Select Yes to overwrite parity if inconsistency is detectedduring disk scrubbing.

6.A.2.2 Scrub Mode

6.A.2.2.1 Manual Scrubbing

This function enables the user to select one array or all arrays to start disk scrubbing. Thisfunction also enables the user to stop disk scrubbing at anytime.



6.A.2.2.2 Schedule Scrubbing

NOTES: If the array is not at its optimum, the controller will cancel disk scrubbing andrecord this event in the event log.

If the InfoStation is not ON at the time of a scheduled scrub, disk scrubbing willnot occur and controller will record this event in the event log.

This function enables the user to schedule disk scrubbing for one array or all arrays.

If enabled, the user can then select Once, Once per week, Once per 4 weeks, Once per8 weeks, Once per 12 weeks, Once per 16 weeks, Once per 20 weeks, or Once per24 weeks to schedule disk scrubbing.

6.A.2.2.3 View Schedule

This function enables the user to check the disk scrubbing schedule.

NOTES: For disk cloning to start, the array must be at its optimum. There cannot beany failed member disks or background tasks (such as adding a disk or ex-panding an array).

Once disk scrubbing starts, the user cannot start any other background taskand array cannot be deleted.

Disk cloning, like mirroring, prevents failure of disks from data loss and unscheduled per-formance degradation.

Disk cloning provides the following advantages:

1. Disk cloning will not prevent normal host access. It will slow down the system'soverall performance however.

2. Disk cloning can be started and processed simultaneously for multiple arrays.

6.A.3.1 Start Disk Clone

This function enables the user to start disk cloning.



6.A.3.1.1-6.A.3.1.2 Source Disk and Target Disk

NOTE: Make sure that target disk capacity is equal to or larger than the source diskcapacity. Disk cloning will not occur if target disk is smaller than the sourcedisk.

Select the desired source disk from the displayed array member, as well as desired targetdisk to be cloned.

6.A.3.1.3 Start Permanent Clone

Select either Yes or No.

Once background copying is done, disk cloning will remain in a state of mirroring. Select Yesfor controller to keep both disks synchronized permanently and replace source disks whennecessary.

6.A.3.1.4 Start Swap after Clone

The source disk array will be replaced by the clone disk, and taken offline.

6.A.3.2 Stop Disk Clone

This function enables the user to manually stop disk cloning.

6.A.3.3 Replace Source Disk

This function enables the user to manually replace the source disk by the clone disk oncebackground copying is done. Disk will remain in a state of mirroring.

6.A.4 SMART

SMART (Self-Monitoring, Analysis, and Reporting Technology) protects user data andminimizes the likelihood of unscheduled system downtime that may result from predictabledegradation and/or drive fault. By monitoring and storing critical performance and calibrationparameters, SMART drives attempt to predict near-term degradation or fault conditions.Providing the host system with such data allows the host to warn the user of impending riskof data loss.



6.A.4.1 Test Disk SMART

This function enables the user to check if a disk supports SMART and the current status ofone disk or all disks.

6.A.4.2 SMART Mode

Select Disable to disable the SMART function for all disks.

Select Enable (Alert only) to enable the controller to check status of all disks. An audiblealarm will sound in the event of a SMART warning.

Select Enable (Permanent Clone) to enable controller to select one spare disk and one clonedisk in the event of a SMART warning. Once disk cloning is done, the source disk will remainin a state of mirroring without replacement.

If there is no spare disk, disk cloning will not occur.

106 Appendix C - Troubleshooting


Appendix C - Troubleshooting

StorCase Technical Support

For assistance configuring and using this StorCase product, contact StorCase technicalsupport at (888) 435-5460.

Setup Problems

• Unable to access the RAID Controller after OS boots up.

Cause - The RAID Controller might not be configured.

Fix - Verify that the RAID Controller is configured for a RAID level. If no RAID level isconfigured, the OS will not detect the RAID Controller as a disk.

• Unable to recognize the disks.

Cause - There might be a disk drive jumper setting problem.

Fix - Verify that all drive jumpers are set to "Master".

• Unable to setup an array using Quick Setup.

Cause - Quick setup can only be used to set up new RAIDs. If the error message 'Array 1Exists!' appears, an array has already been configured.

Fix - Reconfigure the array from the RAID Params submenu.


Appendix C - Troubleshooting 107

Operation Problems

• The front panel LCD displays alternating "Zz" characters.

Cause - This occurs when the cache is full of write request data that has not been processed.The controller will halt requests from the host to flush out data in the cache.

Fix - None required.

• The front panel LCD displays alternating "Ww" characters.

Cause - This occurs when write requests in the cache are being processed. The controllerwill also halt requests from the host.

Fix - Verify that the "Write Buffer" option in the RAID Params Menu is enabled. Increasecache memory if needed.

• The front panel LCD displays "OWOOOS".

Cause - This occurs when there are many bad sectors on a disk drive.

Fix - Change the disk drives.

• Invalid NVRAM message appears.

Cause - NVRAM error or malfunction.

Fix - Save settings and restart controller. Contact StorCase Technical Support if theproblem persists.

• Data loss in Windows 2000 during system shutdown.

Cause - Some data was still in cache buffer during system shutdown.

Fix - Set Cache Off. To shutdown, select Restart System and wait for 30 seconds beforepowering off. Shutdown host OS after shutting down controller.



Remote Terminal Problems

• Unable to access the Configuration Mode using the remote terminal (MonitorUtility).

Cause - The terminal communication settings might not match the settings of the RAIDController.

Fix - Verify that the terminal communication settings of the remote terminal and the RAIDController match. Default settings for the RS-232 port is 19200 Baud, 8 Data Bits,1 Stop Bit, and NO Parity.

Alert Message Problems

• Unable to send a Page or FAX using the MODEM port.

Cause - The Page and FAX options might not be enabled, or the default modem initializationstring may not be compatible with your modem.

Fix - Verify that the Page and FAX options are enabled. Change the modem initializationstring to match your modem (refer to your modem manufacturer's documention forfurther information).

The following modem models require their own initialization strings:

SCSI Problems (For SCSI-to-SATA version only)

• The RAID Controller is not properly identified by the SCSI adapter duringinitialization of the computer system.

Cause - SCSI ID set for the RAID Controller could be the same ID used by another SCSI deviceattached to the same SCSI host adapter.

Fix - Select a different SCSI ID for the RAID Controller. Most SCSI host adapters provideonboard ROM BIOS (or software utility) that displays attached devices and their SCSIIDs. Disconnect the RAID Controller from the SCSI host adapter during system bootand note the SCSI IDs already in use.

• The RAID Controller is identified at all SCSI IDs.

Cause - SCSI ID set for the RAID Controller could be identical to the reserved SCSI ID usedby the SCSI host adapter.

Fix - Configure the RAID Controller to a different SCSI ID. Most SCSI host adapters reserveSCSI ID7.

• The RAID Controller is not detected by the SCSI host adapter.

Cause - Incorrect termination in the daisy-chain configuration, or possibly a loose SCSIcable.
