vgcfgbackup: Invalid LVMREC on Physical Volume /dev/rdsk/c6t11d2

[John McWilliams_1]

We had a disk fail on a L1000 connected to an EMC symmetrix. Before I was notified the failed disk was replaced.

I am now unable to get the new disk working. ioscan shows the disk and it is listed in the vgdisplay.
I have tried pvcreate but get an error about needing the whole disk.
How do I remove the disk from the volume group and recreate it now the original is gone?

thanks John

Hi,

I think you should run vgcfgrestore command.

vgcfgrestore -f /dev/your_vgname pv_path

for details look at man page.

[mirco_1]

use :

# vgreduce vgXX /dev/dsk/c6t11d2

# pvcreate -f /dev/rdsk/c6t11d2

# vgextend vgXX /dev/rdsk/c6t11d2

end then vgchange and vgcfgrestore

Hi,

of course vgcfgrestore -n instead of -f

Hi John,

One more better way of doing it is to boot the system in single user mode then run vgcfgrestore.

hi,

please do the following steps you can use the disk....

1. vgreduce /dev/vgxx /dev/dsk/c6t11d2

2. pvcreate -f /dev/rdsk/c6t11d2

3. vgextend /dev/vgxx /dev/dsk/c6t11d2


thats it.. then you can create lvol's and use it...

Hello All. thank you for your replys.
I was missing one vital step.
First I had to do lvremove to all the logical volumes on the reported disk. Then I was able to do a vgreduce to remove the disk from the volume group.

Next I did pvremove on the disk.

I was then able to do the following steps

pvcreate
vgextend
lvcreate - to make the 3 missing logical volumes
newfs to put the file systems back on.

Regards John

The key to fixing this was the lvremove
