Re: Script to check LVM mirror consistency

Here's a 2 minute bit of korn shell to get you started (apologies about

for VG in $(lsvg -o); do

print -n "$LV :"
lslv -m $LV | awk '{print $3" "$5}' | uniq

Hope this helps.

Has anybody a fast script (perl, ksh or whatever) that can
check the output of

# lslv -m {lvname_xx}

of all logical volumes on all volume groups on an lpar?

A mirror is only consistent, when PP1 and PP2 are on
different physical volumes.

f.e.

root@lpar1:/home>lslv -m hd2
hd2:/usr
LP PP1 PV1 PP2 PV2 PP3 PV3

That's very nice, if you know by the name, to what "side" hdiskx belongs.
A compare of the PVIDs of the hdiskx would show if the mirror-copy is
on the other "hdisk"-side.
Think of two storage systems on two locatitions, which both
have named their pvs "hdiskx".
