hd5 is the boot partition...only used during boot. it will always be closed
when the system is running. Bear in mind that to fully mirror rootvg and be
able to boot, you need to do bosboot -a -d hdisk0 and bosboot -a -d hdisk1
(assuming those are your drive names). it won't do you any good to mirror
your boot drive, but not put a boot block on.
I would remove one of the copies of hd6, though, you don't want to mirror
your swap. i'd add a second swap, the same size as the first on the other
spindle. email me direct if you need more help (just finished doing this on
two boxes today).

Subject: Mirror rootvg questions
Hi folks,
My system: AIX 5.1 running on a 6H1.
I just mirrored the rootvg. There was no problem during the process. The
system came up okay after the reboot. My question is why the LV STATE on
hd5
is different than others. Is this normal?
My other question is that I did not 'mklvcopy' on lg_dumplv. Do I need to?
Finally, how can I be sure the mirroring is working? Can I tell by this
"lsvg -
l rootvg' command?
TIA
# lsvg -l rootvg
rootvg:
LV NAME TYPE LPs PPs PVs LV STATE MOUNT POINT
hd5 boot 1 2 2 closed/syncd N/A
hd6 paging 32 64 2 open/syncd N/A
