Hi,
We have business copies running on our server which somehow gets the data over from another server. None of the mounts are in /etc/fstab and it all seems to run via scripts based in /opt/emc. (emc being the storage).
However we need to initially create the structure on the destination server. (dehp022c is source server and dehp022a is destination server)
Here are the details of the volume group (there is just the one):
dehp022c
Disk Name – /dev/disk/disk99
Volume Group - vg011af2pr06
Lun Name - 0041B
WWN - 60000970000297900683533030343142
dehp022a
Disk Name – /dev/disk/disk246
Lun Name - 0052E
WWN - 60000970000297900683533030343142
So what is the procedure I need to use. The disk on destination server (246) is obviously synced in with the disk on source server (disk99) [so vg011af2pr06 needs to be on /dev/disk/disk246 on destination server (dehp022a)].
Many thanks.
Solved! Go to Solution.

SolutionSince the VG has already been created, all you need to do is import the disk on the destination:
# vgimport -p -v vg011af2pr06 /dev/disk/disk246
The -p option will preview the task.
Run again without -p to import the VG.
Note that the VGname is local to this node so it doesn't have to match the source system.
Very important: sharing this VG must be read-only on the destination. LVM, filesystem structures and file
data must not be changed by the destination system.
There are many pieces of information that are kept in memory but will be unknown by the destination system.
This is nothing like an NFS import.
Importing a business copy is normally used for data recovery.
