Help - Physical Volume contains no LVM Info

[Darren Etheridge_2]

When I run vgscan I get oodles of theses messages:

Couldn't stat physical volume "/dev/dsk/c1t2d0":
Invalid argument
Physical Volume "/dev/dsk/c4t2d0" contains no LVM information
Physical Volume "/dev/dsk/c4t2d1" contains no LVM information

What is the best way to fix this?

Shalom Darren,

The ones that can not be stated are in the volume group in /etc/lvmtab but are not physically present.

The four at the top need to have pvcreate run on them once they are out of the volume group.

I suggest this:

cd /etc
mv lvmtab lvmtab.old
vgscan -a

Pre prepared to run vgreduce -f /dev/dsk/c.... to remove them form the lvmtab file if you choose not to do the first option.

Hi,

As briefed above, the ones showing no LVM information are like free disks ready for use.
These are not used through LVM so far. Allthough these may be in use through some other applications as raw disks.

The one showing missing were previously configured using LVM and are not present now. This is quite possible that these are alternate links to existing disks which has been removed now and that is why you might be surprised that inspite of so many disks missing system is functioning normally.

HTH,
Devender
