We are working on trying out some new HA and/or recovery techniques with SLES
11 SP3 and our new SVC hardware. One thing that I would like to try is
setting up mirroring via the SVC of a LUN that has mysql data on it. This
LUN is dedicated to a SLES 11 SP3 server on our z114, but it is also part
I recommend that you follow the UUIDs and let LVM do the hard part for you.
Each PV in a VG has a unique unit ID. In practice, they truly are
unique. Think of it like a label, but better. The logical volume
manager finds what meta-data it needs on each PV to know what VG it
belongs to and what

Either way, I don't see any reason why you shouldn't use the SVC itself to
mirror the disk(s).
I'd second this approach. One less thing to deal with in software configuration
management.
