Unable to add volume groups

[Joe Robinson_1]

I've posted this in the storage area as well.

I've added two Seagate FW SCSI drives to an external cabinet in order to add disk onto a test box (why buy it when I already have it?); the problem is both drives were used previously and I am unable to add a vg to the system as there are still physical extents being utilized. How can I remove that "image" and start over on these disks?

pvcreate -f each disk before vgcreate.

Hi Joe,

Do a pvcreate -f on both drives first.

e.g. pvcreate -f /dev/rdsk/c2t6d0
pvcreate -f /dev/rdsk/c2t5do

Use the appropriate device path.

You should then be able to do a vgcreate.

As soon as I saw that, I remembered using the force flag; but in doing that, I'm getting "physical volume /dev/dsk/c0t2d0 is already recorded in /etc/lvmtabl". This isn't a file to be manually edited, so... ???

Hi again,

Evidently you didn't do a vgexport to properly clean up. Do a strings /etc/lvmtab and look for the volume group which has the unused/unwanted devices. e.g. vg02

Then, vgexport /dev/vg02

You can also cp /etc/lvmtab /etc/lvmtab.old and do a vgscan to recreate it.
