First, you need to fix you SAN issues, with or without clustering SQL really
likes to have its disks online at all times.
Have you separated your Databases and Transaction Log files? RAID 1 or 10
for the Logs. Raid 5 or 10 for the Databases. Quorum & MSDTC (if required)
on its own disk subsystems of 1 GB in size.
Cheers,
