You will do best if you configure the raid controller to JBOD.
Problem: HP's storage controller doesn't support that mode.
It does, ish. It forces you to create a bunch of single disk raid 0 logical
drives. It's what we do at work on our HP servers running ZFS.
that's different. Among other things, it won't allow tools like
smartctl to work.
The bigger problem is that you have to script around a disk failure, as the
array won't bring a non-redundant logicaldrive back online after a disk
failure without being kicked (which is a good thing in general, but annoying
for ZFS).
How do you replace a bad disk then? Is there some userland tool for
opensolaris which can tell the HP array to bring that disk back up? Or
do you have to restart the server, go to BIOS, and enable it there?
hpacucli will do it (usually /opt/HPQacucli/sbin/hpacucli). You need to:
# Wipe the new disk. Not strictly necessary, but I'm paranoid
hpacucli crtl slot=$n physicaldrive $fixeddrive modify erase
# And online the LD...
hpacucli ctrl slot=$n logicaldrive $ld modify reenable forced
