Solution 1955446.1 : Sun Storage Common Array Manager Drive Firmware Upgrade Fails Silently

Applies to:

Sun Storage 6140 Array - Version All Versions and later
Sun Storage 2530 Array - Version Not Applicable and later

Information in this document applies to any platform.

Symptoms

This document describes a scenario in which both of the following are true:

The procedure in Sun Storage Common Array Manager (CAM) to upgrade drive firmware completes without error. Refer to <Document 1926022.1> Sun Storage Common Array Manager (CAM): How to Upgrade Firmware for Sun Storage 2500, 2500-M2, 6000 Arrays, J4000 JBODs, and F5100 Flash Arrays for details of the procedure.
The firmware on one or more drives did not update as expected.

To verify this is the issue, collect a CAM localhost supportdata (refer to <Document 1021091.1> Collecting Sun Storage Common Array Manager Host Support Data) and open the upgrade log file csmservice.log. The logs confirm that the drive is detected as optimal with its current firmware level which needs to be upgraded as per the following example for drive Tray.02.Drive.05 which has firmware level A700.

Location of the csmservice.log file:

Solaris: /var/sadm/install/se6000/csmservice.log.<array_name>
Linux: /var/opt/cam/csmservice.log.<array name>
Windows: C:\Program Files\Sun Microsystems\se6000\csmservice.log.<arrayname>

Example:

Oct 3, 2014 3:19:25 PM
com.sun.netstorage.fm.storade.device.storage.nge.csm.util.Utility print_debug
FINE: Detected OPTIMAL drive HUS1560SCSUN600Gfor update [2,5] version A700

The drive serial number contains "SN" in the middle. For example: "0012345AB6SN ABCD56SN".

You can quickly see the drive serial numbers with the following command:

# sscs list -d <arrayname> -t disk fru

Where `sscs` is under:

Solaris: /opt/SUNWstkcam/bin/
Linux: /opt/sun/cam/bin/
Windows: C:\Program Files\Sun\Common Array Manager\bin

Cause

CAM is supposed to strip the string which starts with "SN", but unfortunately, it removes any substring ends with "SN". So in this case, the serial number in the report becomes for example "ABCD56SN" while the disk component list returns "0012345AB6SN ABCD56SN". As a result of this mismatch, the firmware is not upgraded.

See the internal <Bug 20108757> (for CAM 6.9) and <Bug 19778233> (for CAM 6.10).

Note: These bugs are opened for CAM 6.9 and 6.10 in order to implement the fixes in these release. However, this problem can affect the previous CAM released too.

Solution

A fix is available with CAM 6.10.2 (aka CAM 6.10 Update). Please refer to <Document 1296274.1> How to Download Common Array Manager (CAM) Software and Patches.

There is no fix or workaround available at this time for CAM 6.9.
