Problem with vgcfgbackup

[Eduardo Ayala Cortés]

Hi Friends,
I have a problem when I want backup volume group configuration, I typed the follow command:

vgcfgbackup vgname

vgcfgbackup: Invalid LVMREC on Physical Volume /dev/rdsk/c28t2d0

Thanks.

You must be a having a disk in there that does not have header informamation or a disk with bad header in that volumegroup, or a disk have been replaced.

Try pvcreate on that disk by pvcreate -f

-USA..

Is c28t2d0 supposed to belong to the VG vgname? If it is, then there is a disk problem. You could try doing a 'vgcfgrestore -n vgname /dev/rdsk/c28t2d0' and then see if you can do a 'vgcfgbackup vgname'.

Hi,

What does pvdisplay says about the disk?
If you do a "strings /etc/lvmconf/.conf"
which disks does it show?
Does the particular disk belong to ?
