Disk Dropped offline in PE2850

[Brian O'Mahony]

Sigh

Two servers in Bangalore decide to stop receiving users requests. I couldn't ssh into them locally, They were powered off and on onsite.

Controller log shows this on both:

11/04 19:19:37: MPT_Rec: INQ Error - Negotiating LD[6] pRfm a0790c20
11/04 19:19:37: Rejecting MISC opcode:  unknown sub-opcode (0x26)

Once again these machines have out of date FW on the PERC. Is that what this error is?

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?
