Drive getting disabled in Device Manager

Medium Priority
Last Modified: 2012-05-11
Dear experts,

We have a Windows 2003 server which is running Veritas NetBackup, this server is having two drive C: and D: (RAID Volumes).  For some strange reason, the D: drive is getting disabled in the Device Manager every few days, the event viewer does not show any errors as such.

Any comments on what could be the cause ?

what is your server brand? also the raid details please


Hi Raneeshcr,

Thanks for the reply.  It is an HP ML 370 G4 server with Windows 2003 SP2 installed on it.  It has 3 physical SCSI drives with RAID 5 configured upon which we have defined two logical drives (C: & D:).

The C: drive shows up fine all the time, but D: gets disabled in the device manager now and then.

i believe you have configured raid through hp smart start cd; could you pls login to the hp utility and check the status of the logical drive; any other logs and psot your updates please;

Are all drivers up to date? Also ensure that the raid bios is up to date as well and that any updates have been applied to the drives as well, as this sounds as though its an issue with the raid card, I would run any HP diagnostics which are available as it will determine the root cause of the problem.

I actually logged into HP Array Configuration Utility and checked it on the first day itself.  The logical drive is up and running, no errors pertaining to any disk or controller.  

HP diagnostic report is clear, no errors no warnings.

Physicall, the disks are fine, no red/amber leds.

Windows events are clear as well, no abnormal error or warning is observed.
