Getting msg: Warning: couldn't query physical volume

[Glenn Mitchell_4]

I'm in the process of setting up a server that was previously used at another account. When system reboots or I run a vgdisplay on vg00 I get the following warning: Could'nt query physical volume /dev/dsk/c1t5d0 and c1t8d0. These devices don't show under /dev/dsk. I evidently need to remove special files (rmsf), but not sure how. Please help

Hi Glenn:

If you do 'strings /etc/lvmtab' you will undoubtedly see the missing devices. To clean this up, do:

# cp /etc/lvmtab /etc/lvmtab.old
# vgscan -av

Pay attention to the man pages for 'vgscan' with regard to alternate (pv) links and your boot disk.

Regards!

You can use the rmsf command to remove the special files. Also, you might want to check the lvmtab file by doing a strings on the /etc/lvmtab file. Sounds like the system thinks that these disks are part of a VG that is still defined on the system. If the disks no longer exist, then you would have to get rid of the VGs associated with the disk using the vgexport command. Finally, you might have to clean up /etc/fstab to remove the any reference to the "bad" VG. Hope this helps.

I believe you rename /etc/lvmtab, then run vgscan.

Just do;

rmsf -a /dev/dsk/c1t5d0

Hi (again) Glenn:

I should have said 'mv' as:

# mv /etc/lvmtab /etc/lvmtab.old
# vgscan -av

Well...

1- run insf -e, to recreate all special files, maybe you had delete it.

2- run strings /etc/lvmtab:

Each vg must contain at least 1 disk. Compare with ioscan -fnCdiks.

3- That disk could be old mirrored disk, so you must reduce all mirrored lvols and then reduce disk from vg. The -f flag must be used if disk is not plugged.

4- Also you can reboot , interact with IPL and boot hpux -lm. So you can export vg00 and reimport.
