interpreting OMSA alertlog entries

[Patrick_Boyd at Dell.com]

Sense data is part of the SCSI standard and you should be able to look this up online. A sense key of 3 is MEDIUM ERROR ASC of 11 with and ASCQ of 0 means UNRECOVERED READ ERROR. So one of your disks is having read errors. You should probably run a consistency check on the VD of which that drive is a part and, if the problem persists, replace the drive in question.

Subject: interpreting OMSA alertlog entries

Hi there,

I've got a PE2950 with a PERC5/i¹ and now I see the following in the
alertlog:

Severity : Ok
ID : 2243
Date and Time : Sat Apr 7 06:15:58 2007
Category : Storage Service
Description : The Patrol Read has stopped.: Controller 0 (PERC 5/i
Integrated)

Severity : Non-Critical
ID : 2095
Date and Time : Sat Apr 7 06:03:01 2007
Category : Storage Service
Description : SCSI sense data Sense key: 3 Sense code: 11 Sense
qualifier: 0: Physical Disk 0:0:2 Controller 0, Connector 0

[... six more of this with some seconds delay...]

Severity : Non-Critical
ID : 2095
Date and Time : Sat Apr 7 06:02:28 2007
Category : Storage Service
Description : SCSI sense data Sense key: 3 Sense code: 11 Sense
qualifier: 0: Physical Disk 0:0:2 Controller 0, Connector 0

Severity : Ok
ID : 2242
Date and Time : Sat Apr 7 03:12:27 2007
Category : Storage Service
Description : The Patrol Read has started.: Controller 0 (PERC 5/i
Integrated)

The events are "Non-Critical", okay. But what do they mean? Where/how
do I get a detailed description for a given event ID? I looked up the
SCSI sense codes and it means "unrecovered read error" - this doesn't
sound like a non-critical event to me, but I'm no SCSI expert...

Thanks for hints and pointers,

Tino.

¹ BTW: The machine didn't have a PERC before - I asked about upgrading
  without backing up which turned out to work partially: I was surprised
  to see my partitions after configuring RAID1 and RAID10. But something
  was inconsistent. I wanted to remove the SW RAID anyway, so I had a
  backup and restored my logical volumes from there.
