As Far as I remember, Sense Key 2 is a "Not Ready" error. Id definitely try 
another drive. Not sure on how DellTech will respond. I have a feeling it may 
depend on the tech you get...

Grepping my log files, I've now had between 50 and 100 each of the following 
messages:

    SCSI sense data Sense key:  2 Sense code:  4 Sense qualifier:  1:
    Physical Disk 0:0:16 Controller 2, Connector 0

    SCSI sense data Sense key:  6 Sense code: 29 Sense qualifier:  2:
    Physical Disk 0:0:16 Controller 2, Connector 0

    SCSI sense data Sense key:  6 Sense code: 29 Sense qualifier: CD:
    Physical Disk 0:0:16 Controller 2, Connector 0

    Controller log file entry: PD 19(e0x11/s16) Path 5000c50005cd0e75  reset
    (Type 03):  Physical Disk 0:0:16 Controller 2, Connector 0

    Controller log file entry: Sense key:  0 Sense code:  0 Sense qualifier:
    0:  Physical Disk 0:0:16 Controller 2, Connector 0

OMSA still marks these as "Status OK" with a big green tick.

I'm tempted to change the disk.  Anyone got any thoughts/comments, here?

On a related note, I'm wondering whether Dell will honour a disk return in 
circumstances where the OMSA logging does not actually consider the disk bad...

Dave.
