[SATLUG] Solaris 9 Partitions and Linux

Actually Solaris on x86 can't read partitions that were created on
Sparc because of endian issues. I found a discussion on it, and the
developers said it won't happen. Luckily the Linux UFS driver does
I found the real issue: the LUNs were part of a RAID, not single
disks. I thought I was looking at 12 single disks, but it's really 2
RAID5 arrays. For some dumb reason they presented single disks to the
Solaris servers then built a RAID across them from the host instead of
doing it on the SAN. Either that, or the SAN driver is messed up and
is showing single disks instead of RAIDs.
