Early versions of Sun StorADE health monitoring software embedded in the service processors of Sun StorEdge 3910/3960 and Sun StorEdge 6910/6960 Arrays and Sun StorEdge 6320 Systems do not correctly handle soft error messages coming from disk drives.  This can lead to unnecessary replacement of disk drives or possible double device failures when an incorrectly diagnosed disk drive is pulled from a working array.

Affected systems/arrays include:

• Sun StorEdge 3910/3960 Arrays without SP Image 2.3.4
• Sun StorEdge 6910/6960 Arrays without SP Image 2.3.4
• Sun StorEdge 6320 Systems without SP Image 1.2.5

To determine the service processor image version, run the following command on SE3910/3960 and SE6910/6960 Arrays.

     # cat /etc/motd
     Sun Microsystems Inc. NWS Service Processor Image Revision 2.3.4  Oct 7, 2004
For SE6320 Systems, run this command.
     # cat /etc/release
     Sun StorEdge(tm) 6320 Service Processor Version 1.2.5
     Patch Released March 14, 2005

Note that these commands are also run as part of "se_extract".  See the results in the extractor output.

The enabling of the volVerify functions in StorADE health monitoring software and the array disk_scrubber may result in an increased level of soft error messages. This occurs because the entire media is being read during the disk_scrubber cycle. During normal operation (w/o disk_scrubber enabled) only a percentage of the media is read and many of the soft errors may not be encountered.    

There are several indications that this issue has been encountered.

1. The StorADE GUI Alarm view page shows ERRORs for recoverable soft errors on disk drives.  Errors are indicated by a red symbol in the GUI alarm view page. Look for LogEvents with the red Error symbol.

2. LogEvent notification receipts with no apparent state or status changes in the disk drives operational behavior.  Look for the absence of orange drive failure lights on the array.

Example: (this is an example of a possible email message from an SE3910.  The message from an SE6320 would be similar.)

   You requested the following events be forwarded to you from 'sp0
   Site     : sitename City State
   Agent    : msp0
   Severity : Error (Actionable)

   PROBABLE-CAUSE:
   Sense Key information indicating a potential problem condition.
   RECOMMENDED-ACTION:
   1. Replace Drive.
   2. Contact support provider.

This issue occurs because policies in the StorADE health monitoring software were deficient with respect to soft disk errors.  The issue is addressed with new service processor images now available for these arrays/systems.

Upgrade the StorADE health monitoring software and the array firmware by installing the latest available Service Processor image.

Follow these general upgrade steps.

1. Schedule time with the customer for the upgrade.

2. Obtain the current upgrade CD.  See minimum versions below.

3. Obtain the current Service Processor image using the steps above, depending on system type.

4. Investigate the upgrade matrix to determine how to obtain the latest fixes.

5. Follow the instructions to upgrade and restore the service processor to an operational state.

6. Follow the instructions to upgrade and restore the individual solution system components.

IMPORTANT NOTE:

To upgrade a 3910/3960 and 6910/6960, a specific upgrade path must be followed.  Each has its own CD. The Field Engineer will have to determine the correct path, then get the CDs for each upgrade.

The paths are:

• 2.0.2 -> 2.0.3

• 2.0.3 -> 2.1.1

• 2.1.1 -> 2.1.2

• 2.1.2 -> 2.1.3

• 2.1.2, 2.1.3 -> 2.1.4

• 2.1.1, 2.1.2, 2.1.3, 2.1.4 -> 2.3.1

• 2.3.1 -> 2.3.2

• 2.3.2 -> 2.3.3

• 2.3.3 -> 2.3.4
