Merging volume groups

[stawolg]

I have two non rootvg volume groups each with two identical PVs on my server. No I have to merge them to a single VG without loss of data. Is there any comfortable method to do this instead of FS backup followed by delete vg, extendvg and restore of FS?

You could copy logical volumes from old volume group to new volume group using the following method:
Step 1: umount [filesystem]

Step 2: cp [oldLV] [newLV]
cplv –v VG(destination) –y [newLV] [sourceLV]

Step 3: chfs to recognize [newLV]
chfs –a dev=/dev/[newLV] –a log=/dev/[logdev] /[filesystem]

Step 4: fsck –p /dev/[newLV]

Step 5: mount [filesystem]

Step 6: rm [oldLV]
rm [oldLV]

I know an uncomfortable way to do it. If the above does not work, let me know. IBM Certified -- AIX 4.3 Obfuscation
