Disk Dropped offline in PE2850

[Brian O'Mahony]

Opened a ticket with Dell. I knew the PERC FW was out of date and mismatched to the driver version as we updated the Os to rhel4u6. However it being a live clearcase VOB server, getting downtime is next to impossible. Of course, until something like this happens and they realize the problems

Updating the PERC and driver fw later today so hopefully that will all be fine.

F4 is only a timeout. I nearly all cases, driver and Firmware Update will fix it for the future.
Check also the disk FW.

This is more of a general question rather than linux specific.

A disk dropped offline this morning in a RAID5 array. Machine is running rhel4u6. The dedicated hotspare did NOT kick back in.

There is no sense key errors in the controller logs, no predictive fails or SMART errors. Log says disk was removed and then 5 seconds later reinserted.

The only thing I can find in the controller log is:

fail_reason=f4, channel=0, target=3

Its obviously the right disk, 0:3. What does fail_reason=f4 mean does anyone know?
