Restore a rootvg WPAR into another AIX server

Question & Answer


Question

When restoring a rootvg wpar image into another LPAR, we face a device ID erros

Cause

The cause for this issue is the wpar.spec file is using the source LPAR disk UUID in the new destination LPAR restore operation

Answer

To overcome the UUID issue, The following procedures should be followed:

1) Backup the WPAR from source LPAR_1:
LPAR_1# savewpar -f /tmp/WPAR.img WPAR_NAME

2) Copy /tmp/WPAR.img image and /tmp/wpardata/LPAR_1/wpar.spec files
To the destination LPAR_2 new directory: /tmp/LPAR_2

3) Edit the /tmp/LPAR_2/wpar.spec file on the destination LPAR_2
And change disk device devid's to the new disk devid's on the destination LPAR_2:
# vi /tmp/LPAR_2/wpar.spec
Step_3 is the most important one, since the most difference between LPAR_1
And LPAR_2 is the disk UUID.

4) Change networks to new IP addresses if necessary.

5) Now issue the restwpar command:
LPAR_2# restwpar -a -M "-L ignore_maps=yes ignore_lvs=yes" -f /tmp/LPAR_2/WPAR.img -w /tmp/LPAR_2/wpar.spec


Thank you for taking time to read through this note.
