If you are planning on configuring your LPARs (in a dual Virtual I/O Server environment) with AIX LVM mirroring, then you may find this tip interesting. Anyone who is already running this type of configuration is most definitely aware of the information I’m about to share with you.

Here are some scripts that can aid in "automating" the recovery process.

FYI - The "rootvg_on" script simply recovers from a missing pv in rootvg. The "fixdualvios" script does the same but also caters for MPIO, non-LVM mirroring and NIB configurations (with dual VIOS).
