SCSI Physical Drive Status Change

[Pete Wagner]

Over the past couple weeks, the following Storage Agent error is written to the System Log several times a day. This is on a ML350 running Insight Management Agents 7.40 under Windows 2000 Server SP4.

Description:
SCSI Physical Drive Status Change.
The SCSI physical drive with SCSI target 2 connected to SCSI bus 1 of the controller in slot 1 has a new status of 10.
(Drive status values: 1=other, 2=ok, 3=failed, 4=notConfigured, 5=badCable, 6=missingWasOk, 7=missingWasFailed, 8=predictiveFailure, 9=missingWasPredictiveFailure, 10=offline, 11=missingWasOffline)

Then exactly 2 minutes later another entry to the System Log shows the drive is ok.

The SCSI target ID varies between the 4 mirrored drives on the onboard controller. Management Agents show no failure or errors on the drives or controller. The controller shows one soft reset. Any ideas as to what could cause this?
