couldn't query physical volume

[uk1]

I am still researching this but seem to be at a brick wall and could use some guidance. Currently the below is the output of vg02 on my system. Problem is I cant seem to remove the disks that are being displayed in the cant query status. I have removed lvmtab and ran vgscan but the disks still show up belonging to vg02. Could this be an issue with alternate links? Or will I need to export the vg and reimport it?

The first thing that you need to do is an ioscan -C disk -fn and see what devices are really out there. It's also possible that your SAN and array disy array management software has disallowed this host. An ioscan should tell what disk devices (LUN's) the HP-UX box can actually "see".

[uk1]

Very good idea. I checked the output and it does appear that they are seen and do have device files

This sounds vaguely familar - does the following thread help?

[Sandman!]

Clay is absolutely right. Do an ioscan to make sure that the disk and device file are CLAIMED and diskinfo the raw device file should report the correct size.

# ioscan -fnC disk

# diskinfo /dev/rdsk/cXtYdZ

hope it helps!

Hi David,

Clay is right. You have to confirm if the LUNs have got a new device file.

It will be useful if you throw some light on the activities done before this problem cropped up. Were LUNs deleted/created newly?

If your concern is only to remove these entries from the VG, backup the file vg02.conf and then perform vgreduce -f (check man page).

This should clear out the missing PV entries.

But there is a mismatch between the lvmtab file and the vg02.conf file. The Act PV and Cur PV value matches. So it will be important to reverse engineer the cause of this problem.

With regards,
Mohan.

DCE that worked like a charm. Can anyone explain why putting it in low quorm mode worked in this situation. Curious.

[uk1]

Ah found it in the man page

The -q n option can be used to activate the
volume group when the disk quorum is not
maintained because too many disks were lost.
Since it ensures the integrity of the LVM
configuration information, it is normally not
advisable to override the quorum.

Thank you all for your help. This form is wonderful.
