Solution 1019002.1 : Collecting Support Data On Certain Arrays May Cause One or Both Array Controllers to Reboot

1. Impact

For Sun StorageTek 6130, 6140, 6540 and Flexline 240, 280, and 380 arrays, collecting support data may cause one or both array controllers to reboot. Results can range from device path failovers to loss of access due to both primary and secondary paths to a device being inaccessible.

2. Contributing Factors

This issue can occur on the following platforms and in the following releases:

Sun StorEdge 6130 arrays with array firmware 06.19.25.10 (or later)
Sun StorageTek 6140, 6540 arrays with array firmware 06.16.81.10 (or later)
Sun StorageTek Flexline 240, 280, 380 arrays with array firmware 06.19.25.00 (or later)
Sun StorageTek SANtricity Storage Manager 06.16 (or later)
Sun StorageTek Common Array Manager 6.0

Notes:

This issue can only occur during array support data collection using SANtricity or Common Array Manager (CAM). Specifically the "Capture State" function of the collection which generates the stateCaptureData.dmp file.

The following specific circumstances lead to this bug:

1) The Host Port/HBA must be or have been seen in the SAN by one or both controllers. This can be verified if it is listed in the WWPN drop down in CAM, or as an un-aliased Host Port in SANtricity. This means that "fake" WWPNs that are aliased on the array, or proactively created before the SAN is zoned WILL NOT cause this issue.

2) The Host Port/Initiator must have an existing alias. This means that not only had the HBA been seen by the array, but at some point the user had created an alias for it to assign to a specific host for Volume-to-LUN mapping on the array.

3) Since having been aliased, as in step 2, the Host Port/Initiator must have either:

A) been removed from (unliased) and placed in the "Free" list (available as a drop down in CAM)
or

B) had the alias name changed

4) After conditions 1-3 are met, the execution of collecting the "All Support Data" or specifically the "State Capture" (SANtricity Only) will cause the controllers to panic.

3. Symptoms

At a minimum, users will see device path fail-overs. At worst, they will see a loss of access due to both primary and secondary paths to a device being inaccessible.

This issue can only occur during array support data collection. Host message events showing SCSI or Fibre Channel messages indicating loss of access to one or both array controllers are the most common symptom associated with this issue. SANtricity or CAM may throw an error during collection, similar to the following (CAM error shown):

    ionShow 99 fails!
    devmgr.v0916api13.sam.jal.ManagementOperationFailedException:
    ManagementOperationFailedExceptionError 1007 - Could not communicate
    with the controller in slot A to complete this request.

The controller(s) will boot due to a defined inititiator or host port not being seen by the array at the time the data collection command is run.

4. Workaround

This issue can be avoided by not collecting support data when you know that:

A) An Initiator/Host Port alias for a connected HBA has been changed

B) An Initiator/Host Port alias has been deleted from the array. This is normal if you replace/remove an HBA as part of reallocation or hardware replacement.

If either of the above, consider performing a controller reset to avoid an unplanned outage.

Otherwise, individual collections of "Alarms", "Array Profiles", and "Major Event Logs" are possible within each of the management utilities.

The following CLI commands can be run to obtain support data for CAM:

    service -d <array_name> -c print -t arrayprofile > arrayProfileSummary.txt

    service -d <array_name> -c print -t mel > majorEventLog.txt

    service -d <array_name> -c read -q nvsram region=0xEE > NVSRAMdata.txt

    service -d <array_name> -c print -t rls > readLinkStatus.csv

    sscs list alarm > alarms.txt

The following SMcli or script editor commands can be run under SANtricity:


    save controller [a] NVSRAM file="A-NVSRAMdata.txt"

    save controller [b] NVSRAM file="B-NVSRAMdata.txt"

    save allDrives logFile="driveDiagnosticData.bin"

    save storageArray configuration file="storageArrayConfiguration.txt" allConfig

    save storageArray allEvents file="majorEventLog.txt

    save storageArray performanceStats file="persistentReservations.txt"

    save storageArray RLSCounts file="readLinkStatus.csv"

    show storageArray profile

5. Resolution

This issue is addressed in the following releases:

Sun StorEdge 6130, 6140, 6540 arrays with array firmware 06.60.11.10 or later
Sun StorageTek Flexline 380 array with array firmware 06.60.11.10 or later
Sun StorageTek Flexline 240, 280 arrays with array firmware 06.60.11.20 or later
Sun StorageTek SANtricity Storage Manager 10.10 or later
Sun StorageTek Common Array Manager 6.1.0 or later

The above firmware releases are available with CAM 6.1.0 at:

Note: Firmware 07.10.25.10
is the next revision up, but is not bundled with CAM. In order to obtain
this Firmware, a call with Sun Support is required.

If stateCapture is required, please escalate the issue, and a tailored serial collection sequence will be made available.

Controllers will report an exception in the exception log(excLogShow) as in the following example:
