AIX - LVM - Mirror Volume Group

AIX - LVM - Mirror Volume Group

We can do mirroring in AIX, using mirrorvg command and we can create max of three copy of mirror.

If we have two PV’s in rootvg, now we want mirror, Data and OS installed in hdisk0 and now we want to mirror hdisk0 to hdisk1. Then your command will be

#mirrorvg –S –m rootvg hdisk1

S – Backgroup mirror
-m - exact (force) mirror

NOTE: in mirrored VG quorum should be off line because quorum is not recommended for mirror.
