Clarification requested.
You have two disks in the one vios lpar and two disks in the other vios
lpar, right?
And you are mirroring disk 1 of vios 1 to disk 2 of vios 1, and,
disk 1 of vios2 to disk 2 of vios2?
Or, you created one storage pool on vios for IBMiLpar and started that,
then
you created another storage pool on vios for IBMiLpar but this second one
is just for a mirror of the first storage pool?
Never tried mirroring at the storage pool level. Normally I use mirroring
at the vios level because of the small number of disks and RAID 5 or 6 at
the IBM i level. And I use IBM i to host internal disk.
We did try hosting IBM i from internal disks using VIOS. Was a
performance dog!!!! Initialized the whole damn thing and started over -
it was that bad. Hosting IBM i from Vios disk is only recommended for
external storage, such as a SAN.
Your situation may be different though. Maybe you're trying to get two
redundant mirrored Vios lpars going both hosting IBM i and trying to do
that with a minimum number of disk drives figuring they are so darned big
nowadays that it seems like a waste of space for just vios.
