12h autoraid - missing disk & recovery failed warnings

12h autoraid - missing disk & recovery failed warnings

We had a 12H crash and upon restarting it would hang. We replaced the disk in A3 and the array added the drive and rebuilt (auto-include, auto-rebuild auto-hotspare are all enabled). Since then we have two errors: missing disk, recover failed reported by arraydsp -s. If we try to rebuild the array (arrayrbld -r), we are told that no recovery is needed. Using mstm, I have excersised the array and it reports back ok. I think that the missing disk and recovery warnings are bogus. Is there any way to clear the warnings short of wiping the array?

Shalom,

New disks need to be initialized with pvcreate

They also may need to be forced out of the volume group configuration prior to replacement.

Found it outside the HP net as well.

Steven,

The disk in question is under the control of the array, it's not in the chassis of the server, so I don't see how the logical volume manager comes into play. No changes were made to the size of the volumes on the array or the server's disks.

Re: 12h autoraid - missing disk & recovery failed warnings

Not speaking from experience on this, but after you replaced the disk in A3 and received the missing disk warnings, have you attempted to restart the 12H? (arraymgr shut/start)

Re: 12h autoraid - missing disk & recovery failed warnings

see this link for the System Admin Guide for the 12H. check out pages around 52-53 for command line diagnostics, non-destructive tests of a disk in a specific slot and how to read / clear the hardware log in the array.

I suspect the monitor is picking up the death of the old drive from that log, but I can't confirm that (no more autoraids on site)

Dennis,

We have shutdown the array using the array front panel.

OldSchool,

I had cleared the logs for the disk in slot A3 (the only one we replaced) as well as the controller.

ghpts1:/# arraylog -e PTSMAIN

Primary Controller = X

Controller X Vendor ID = HP
Controller X Product ID = C5447A
Controller X Firmware = F209030416
Controller X Serial Number = R85FADF979691111
Controller Y Vendor ID = HP
Controller Y Product ID = C5447A
Controller Y Firmware = F209030416
Controller Y Serial Number = R84TADF940971111
No Events in Log

ghpts1:/# arraylog -u PTSMAIN

Primary Controller = X

Controller X Vendor ID = HP
Controller X Product ID = C5447A
Controller X Firmware = F209030416

Re: 12h autoraid - missing disk & recovery failed warnings

did you try "drivetest" (pg 52 in the linked doc?)

Re: 12h autoraid - missing disk & recovery failed warnings

No idea if it really is, but it could be a firmware issue, because you are running hp54 and latest for this oldie was hp62.
Caution, if you ever find this firmware and consider an update, update the commands patch first!

Hope this helps!
Regards
Torsten.

OldSchool,

Yes, I did a drivetest and it passed.
