Working with volume groups that have the same name (cloned disk, recoveries, etc)

First, we attach the vmdk to the vm and then scan the bus to see it in linux:
# echo “- – -” > /sys/class/scsi_host/host0/scan

In this scenario, /dev/sda2 and /dev/sdb2 have the same volume group name of VolGroup00, let’s rename /dev/sdb2 to VolGroup01:
# vgimportclone –basevgname VolGroup01 /dev/sdb2

next let’s find the new VolumeGroup:
# vgscan
# vgchange -a y

Now let’s mount the LV we want from the new volume group:
# mount /dev/VolGroup01/LogVol02 /mnt/restore/

Once we’re done, we want to unmount the LV and remove reference to the VG
# umount /mnt/restore
# vgchange -an VolGroup01 (make VG unavailable)
# sync

Remove the drive, wait a few minutes and let’s do a rescan:
# vgscan
