VG activation error after Server is migrated from 1 DC to another, with 3par disk replication

[3r]

Hi Team,

I have a server rx6600 with HPUX 11.31, that was ship and lift from one DC to another. There are 3par luns configured in the server, which are replicated to both DC 1 and 2. Now that server is in new DC2 coming from DC1, the vg disk information was change as stated below.. Thus we cannot activate the vgs.

vgchange -a y /dev/vgcldp01
vgchange: Warning: Couldn't attach to the volume group physical volume "/dev/disk/disk30":
The path of the physical volume refers to a device that does not
exist, or is not configured into the kernel.

if you have different special device files now, you need to vgexport/vgimport the VG.

Hi Torsten,

Please see specific error below, the old disks that was save from map files are /dev/disk/disk30, /dev/disk/disk31 and /dev/disk/disk32 and since the server was move from another DC. This disks are now not available, and the replicated disk from local storage is /dev/disk/disk109. Now the question is how can I add this new disk that holds its data to activate the VG.

Will the below option from man page, could sove the issue:

Restore LVM configuration information stored for /dev/rdsk/c0t7d0 in
default configuration file vg01.conf to physical volume
/dev/rdsk/c0t6d0:

vgcfgrestore -n /dev/vg01 -o /dev/rdsk/c0t7d0 /dev/rdsk/c0t6d0

Hi Torsten,

I think the main issue is that the disk was renumbered from the vg, since the server was transfered from one DC to another with different storage, But the disks from storage are replicated to keep data consistent to different DC, now the question is how to activate the VG with the new disk and is it possible to still have the data intact?

Hi Torsten,

vexport/vgimport did work but for some it had an error like below. Hope you can help me on this.

vgimport -s -m /tmp/vgDP.map /dev/vgDP /dev/rdisk/disk71 /dev/rdisk/disk72 /dev/rdisk/disk73 /dev/rdisk/disk74 /dev/rdisk/disk75 /dev/rdisk/disk76 /dev/rdisk/disk57

Couldn't access the list of physical volumes for volume group "/dev/vgDP"

# vgchange -a y /dev/vgcldp01_3par
vgchange: Couldn't activate volume group "/dev/vgcldp01_3par":

just to start, run

vgscan -p -v

and tell the result.

hi Torsten, 

For issue: 

# vgimport -s -m /tmp/vgDP.map /dev/vgDP
Couldn't access the list of physical volumes for volume group "/dev/vgDP".

below is the vgscan -p -v output:
