Solution 1509311.1 : How to isolate disk problems on an Adaptec RAID controller (Cougar)

Applies to:

Sun Netra T5440 Server - Version Not Applicable and later
Information in this document applies to any platform.

Goal

Determine how to isolate disk issues on an Adaptec RAID controller (Cougar)

Solution

Explorer message files & console logs are not usually helpful to isolate disk failures when placed in a hardware RAID volume. Explorer 6.5 collects Adaptec RAID controller event logs (event_1.out), configuration file (getconfig_1.out), & other files in the RAIDmanager directory. Explosum will parse these files to provide a summary of the configuration & problems.

If the customer has an older version of explorer or does not wish to submit an explorer, please request output from the following commands:

   cd /opt/StorMan
   ./arcconf getversion
   ./arcconf getstatus 1
   ./arcconf getconfig 1
   ./arcconf getlogs 1 event
   ./arcconf getlogs 1 device

Also obtain files:

   /opt/StorMan/RaidEvt.log
   /opt/StorMan/RaidEvtA.log
   /opt/StorMan/RaidErr.log
   /opt/StorMan/RaidErrA.log

If the boot disk is affected, then you must boot via the Live CD which is obtained by Intel's site. Please choose the correct executable for the system & burn to CD.

The configuration file contains the following information:

   Logical Dev: 0 Simple_volume Optimal 285686 MB Present (0,8)       Bootable
   Logical Dev: 1 Simple_volume Optimal 285686 MB Present (0,9)

Please notice that the info above contains more data, but is a summary of the configuration. It also indicates if the volumes & physical devices are online or failed. It also indicates if the controller determine that a device has encountered a SMART error, which predicts possible failure in the future.

The RaidEvt.log contains a daily list of installed devices & an event of disk failure, removal, & insertion, as follows:

   October 10, 2012 1:15:46 PM GMT ERR 401:A01C0S12L-- txslimsccf4 Failed drive: controller 1, enclosure 0, slot 4, S/N 00100271BM4V 3SE1BM4V (Vendor: SEAGATE Model: ST930003SSUN300G).

These messages indicate that the disk in slot 4 has failed & was replaced 6 days later. Please notice that a newly inserted drive usually creates a failure to spin up, which should be ignored.
