Claimed disk but cannot be quiried

otukile — Fri, 03 Dec 2004 03:00:22 GMT

W have 2 lun disks on an FC60 which form a volume group on a 11.0 server. On reboot, it comes up with message that it cannot quiry the disks. Running ioscan shows the disks as claimed. Other disks (luns ) of the same nature have activated without a problem. Any clues as to what we could be doing wrong.

HI,
If the LVM info on the Disk is Lost you may need to use vgcfgrestore.
See man vgcfgrestore.
Hope that helps.
Regards,

ps. send the output of "ioscan -fnC disk"

The disk/LUN may be defective. It will still show up in an ioscan, however, you cannot query it.

Try to do a "diskinfo /dev/rdsk/cXtXDX" on the drive/LUN. If it cannot be displayed, you have a hardware problem.

things to try / check :)

- diskinfo to raw device
- lssf on /dev/*dsk/device
- dd /dev/rdsk/device /dev/null count=100 bs=1m
scsictl -a /dev/rdsk/device

where does it break?

- ioscan -fnd (is the sdisk driver bound to it?)

Unfortunately I don't have an FC60 myself at hand, but were are some utilities with every HP array I came to see to query disk and enclosure states, so I hope this also accounts for the FC60.

From the docs I just found, it even should log to stm, check mstm -> run -> utility -> logtool for fc60 errors.

Good luck,
