StorageTek 2500 Series Array Features

The StorageTek 2540, 2530, and 2510 arrays, along with the StorageTek 2501 expansion module, make up the 2500 family of arrays.

The StorageTek 2500 arrays contain disk drives for storing data and controllers that provide the interface between a data host and the disk drives. The StorageTek 2540 array provides Fibre Channel connectivity from the data host to the controller. The StorageTek 2530 array provides Serial Attached SCSI (SAS) connectivity from the data host to the controller. The StorageTek 2510 array supports Internet Small Computer Systems Interface (iSCSI) over Ethernet networks.

The StorageTek 2501 expansion module provides additional storage. You can attach the drive expansion tray to the StorageTek 2540, 2530, and 2510 arrays.

About Common Array Manager Software

The Sun Storage Common Array Manager (CAM) software provides an easy-to-use interface from which you can configure, manage, and monitor StorageTek and Sun Storage arrays.

Downloading Patches and Updates

Download the latest platform and firmware patch (see TABLE 1-1) from My Oracle Support (MOS).

For detailed patch download steps, see the Knowledge article 1296274.1 available on MOS.


Note - Each array should be managed by one CAM management host only. Installing the management software on more than one host to manage the same array can cause discrepancies in the information reported by CAM.

Replacing a Simplex Controller


Note - If the controller is a replacement for a duplex controller environment, do not read further. Use the Service Advisor procedure to replace the unit. From the Sun Storage Common Array Manager application, click the Service Advisor button and follow the instructions.

1. Verify your Common Array Management Software is at the 6.2.0 level or later.


caution icon Caution - Do NOT use the -f option to uninstall the previous version of CAM.

See Downloading Patches and Updates to obtain the latest CAM information and version available.

2. Replace the controller.

For details, see the Sun StorageTek 2500 Series Controller Removal and Replacement document.

3. If CAM shows the array is in working order, no further action is needed.

4. If after two minutes from powering the array back up CAM still reports “Communication Lost,” then run the following:

# cd /opt/SUNWsefms/bin

# ./csmservice -i -a <array-name> -Z UNLOCK -w

# cd "c:\Program Files\Sun\Common Array Manager\Component\fms\bin"

# .\csmservice -i -a <array-name> -Z UNLOCK -w

# cd /opt/sun/cam/private/fms/bin/

# ./csmservice -i -a <array-name> -Z UNLOCK -w

Results: The correct controller firmware will be loaded, the array will reboot, and CAM should report array status.

Notable Fixes

Firmware revision 07.35.72.10 delivers the following fixes:

Known Issues

The following sections provide information about known issues and bugs filed against this product release:

Important Notes and Considerations


Note - For the latest firmware information, go to: http://docs.oracle.com/cd/E24008_01/index.html and open the Array Baseline Firmware Reference PDF.

Avoiding Firmware Issues

Configuration, Firmware and Hardware Issues

Battery Events Do Not Identify the Battery’s Controller Location

Bug 6503171 - Battery event messages do not specify which of the two controllers the referenced battery is in.

For battery events, the array only reports the tray where it occurs, not the slot.

Workaround - For non-critical events, collect the support data and find the corresponding event in the MEL log. For critical events, the third amber LED lights on the front of the controller with the failed battery.

Cache is Disabled when Batteries are Charging

Please be aware that until batteries are fully charged, your system might experience lower than normal performance during: events that disable cache, battery learn cycle, battery charge cycle, battery charge level below necessary charge level (preceeding a battery charge cycle).

Controller Slot Positions Contained in MEL Log are Unreliable

Bug 6747684 - The controller redundancy lost event is showing the wrong controller slot in the component field on a 2530 array.

Workaround - Review CAM Service Advisor/Alarms for more information regarding which controller has actually lost redundancy.

Controller Tray and Drive Expansion Trays - Turning off the Power

caution icon Caution - Before turning off the power to the drive expansion trays connected to the controller tray, you must turn off the power to controller tray. Failure to do so may cause a volume configuration loss which is not reversible.

Create Volume Fails on ESM During First Attempt

Bug 6767895 - Create Volume command fails on first attempt using 25x0 controller, resulting in an error message similar to the following: “An unexpected internal system error occurred. Retry the operation and then contact your Oracle service representative if the error persists.”

Disabled Snapshot can be Re-enabled after a Firmware Update

Bug 6529172 - A snapshot volume that is disabled can be automatically re-enabled after a firmware update occurs. If the snapshot volume is full, it can start generating warning events.

Workaround - Disable the snapshot again after the firmware update.

Expansion Module with Licensed Domains Causes Event

Bugs 6550702 and 6547615 - If you migrate an expansion module with licensed storage domains into an array that has a different number of licenses, an alarm will be generated.

Workaround -For a mismatch of license numbers, disable the licenses on the expansion module. Then, disable the storage domains on the expansion module. The array will return to the licenses for the array, and the alarm will clear. Add any new licenses, if needed.

LED Lights After Data Host Power On

Bug 6587720- The Array Service Required LED will light after powering down a data host, connecting FC cables between the HBA and controllers, and powering up the host server.

This is working as designed. Under a Direct Connect environment, rebooting the connected data host will cause a FC link down alarm. This is an expected alarm and the Amber Service Required LED is expected to illuminate. As soon as the link is back up, the Alarm should clear and the LED should turn off. The same behavior would be expected if a cable were unplugged from the HBA, or if there were an error with the HBA port or the HBA itself.

Under a switch environment, this will not occur unless a cable is unplugged from the switch, the switch is rebooted, or is having errors. Rebooting the host will not cause the link to go down because the link from the controller SFP to the switch will remain up.

mpathadm Does Not Reflect Accurate Path Count After Moving or Removing a Path

Bug 6579069 - Using the “mpathadm” command to remove a path from the system or relocate from one path to another, the “Total Path Count” will not update until the system is rebooted.

Workaround - Reboot to clear the extra path.

Select File Button Does Not Work

When you use the Simplicity storage management software to download a firmware update file for an 2540 array module, the Select File button does not work.

Workaround - Enter the file path and file name into the Filename text box.

Service Advisor Does Not Verify Disk is Ready to be Removed

When CAM shows a disk is failed and the Service Advisor procedure for replacing drives is followed, the step to verify that the disk is ready to remove might not list the failed disk.

Workaround - Use an alternative menu option, Array Troubleshooting and Recovery, to view disk status.

SES vs. SD Paths for UTM LUNs.

Bug 6500605 -For Solaris 10u4 and Solaris 8 and 9, the host cannot see the storage device's management UTM LUN.


Note - This bug is fixed in S10u5.

Workaround -Perform the following commands on the data host:

# setenv LD_LIBRARY_PATH /opt/SMgr/agent

# java -classpath /opt/SMgr/agent/SMagent.jar devmgr.versioned.agent.DeviceIdentifier | grep “Volume Access”

You should then receive output like the following, indicating which arrays have access LUNs visible to the agent: 

/dev/rdsk/c5t200600A0B82458D4d31s2 [Storage Array fms-lca1, Volume
Access, LUN 31, Volume ID <600a0b80002458d20000000000000000>]
/dev/rdsk/c5t200700A0B82458D3d31s2 [Storage Array fms-lca1, Volume

Access, LUN 31, Volume ID <600a0b80002fc0740000000000000000>]

Small Form-Factor Pluggable (SFP) May Not Generate a Fault Indicator

Bug 6514739 - If a bad SFP is inserted in the FC port of a 2540 array, there might be no indication it is bad.

Certain failure modes of an SFP may not be detected by the array firmware immediately upon insertion and the management software could report the link state as optimal. However, when you initiate I/O on the channel with the damaged SFP, it will be reported as failed.

Workaround - Check the fault LED and link LED for link failure. Check the event log for a failure event at the time of the SFP insertion and when you initiate I/O.

Upgrade Utility Automatic Array Discovery Password Verify does not Reference the Array

Bug 6736963 - When multiple arrays are discovered (using the Automatic scan subnet option), the Password Verification pop-up windows do not make reference to the array. Workaround - In progress.

Upgrade Utility Intermittently Fails

Bug 6723212 - Sometimes the upgrade process appears to hang, and it appears the firmware did not install. The Graphical User Interface (GUI) eventually times out, and the log contains an “Error downloading file(s) to the array” message.

Workaround - Try the upgrade process again. If failure persists, upgrade to 6.70.54.11 before attempting to use the upgrade utility.


Note - For the latest firmware information, go to: http://docs.oracle.com/cd/E24008_01/index.html and open the Array Baseline Firmware Reference PDF.

UTM LUNs Controlled by “Solaris Traffic Manager”

Bug 6594360 -After you upgrade to S10U3 (or later), the in-band management UTM LUNs are controlled by Solaris Traffic Manager (MPxIO). In most cases, in-band management will not fail as a result of this; however, it is best practice to ensure that the UTM LUNs are not controlled by MPxIO. Performing the following workaround task will help prevent problems.

Workaround -Use the format inquire command to get the eight-character Vendor (VID) and Product IDs. Use the procedure that follows.

1. Edit the file /kernel/drv/scsi_vhci.conf so it reads:

device-type-scsi-options-list = “SUN Universal Xport”, “disable-option”; disable-option = 0x7000000

2. Run the stmsboot -u command. Answer “y” to continue and reboot the system immediately.

iSCSI Issues

Initiator with the Same Name as a Host Creates an Error

Bug 6624755 - For iSCSI on the 2510 Array only, creating an initiator with the same name as a host returns error message 57: “The operation cannot complete because the identifier or name you provided already exists. Please provide another identifier or name and then retry the operation.”

Workaround - Do not create an initiator with the same name as a host.

Out-of-Band Management May Lose Connectivity

Bug 6615356 - SYMbol task ServsymRpcHandle periodically dies, causing the management software to lose communication with the array.

The cause has been identified and will be corrected in future releases.

Workaround - Run the nicStop and nicStart commands. For more information, run nicHelp. If the issue persists, reboot the system.

Values Returned for iSCSI Statistics Counters are Negative

Bug 6611655 - Negative counter values display for iSCSI Statistics large counter values. The values should be unsigned.

Workaround - From Administration->Performance, click Reset Values.

SAS Issues

Creating New Volumes During Heavy Input-Output Can Result In Errors

Bug 6522938 - For SAS, using the CLI to create a new volume on an array with high data input and output returns in a timeout and an error code of 4.

Workaround - Re-try the operation when there is less I/O traffic.
