It looks as if the RHEL lpars were restarted  on the 27th  wondering if there is any correlation on these events.
And the AIX c2o on the 28th

    SCSI Bus problem perhaps?  Maybe the bus on the device or cable is defective?

    Accepted Solution


    most probably there was a failure in some component of your SAS disk array fabric.

    Follow this fault isolation procedure as exactly as you can to identify the root cause of your problem:

    Most probably you will then have to call IBM support to possibly replace the failing resource.

    And - you should ensure that device, device enclosure, and adapter microcode levels are up to date!
