PV Status = unavailable

[Shaamil]

Hi Guys
Can anyone tell me why the pv status of the pvdisplay command shows unavailable.
Also how can I change it to availible.
I also just got the following error message
from syslog.

See attached .txt file

You've got scsi problems...

Have you changed any cabling, or added/powered up hardware recently?

strings /etc/lvmtab

and look for the pv device file.

(the volume group it is in is listed above the pv device file)

ioscan -fnk | more
and view the hardware state of the disk and scsi interface up to the pv... verify it is claimed (and not NO_HW for example)

Later,
Bill

hi

it's very generic descripion can you send more information?

have you a cluster? have you a external storage?

First do a ioscan -fnC disk to get the status of the disk.

If the disk is claimed,then look for the cable connections.
Might be the cable connecting the disk is loose.


If it does not show up claimed,then check the cables and do a
insf -e
to re-install the device files for the disk.

Thanks

HI
I will post some more info for U guys later, the server crashed & will not come up. The server is physically in Australia & I am in South Africa. Our guys there have logged a call with HP.

I think it's going to come up with one less disk, if it comes up at all. (mirrored?)

I'd imagine, it tried to page in something from the failed disk and boom..

Enjoy your trip,
Bill

Hi,

Looks like one of your disks at c0t9d0 is having some problem. Best idea would be to replace the disk. Check and see if the disk is seen as claimed in the ioscan output, "ioscan -fnC disk". also check if the disk parameters are displayed correctly in the diskinfo output, "diskinfo -v /dev/rdsk/c0t9d0". If the two outputs don't show the disk correctly, replace the disk, do a vgcfgrestore for the vg that was on the disk and do a vgsync. You won't looks anything if the disk is properly mirrored and the mirror copy is fine, else you may looks some data depending on what filesystem are there on the disk.

Hope this helps.
