Please correct any of the following that are wrong:
I assume the SAN is separate & only needs to be connected to server2.
I assume that server2 is also a single drive unit & which is at least 80 GB.
You mention "vg00" in 2 contexts: server1 & the SAN storage connected to it. Are these 2 different LVM systems, or are they 2 PV's assigned to a single VG? (I hope the former.)
I have seen Clonezilla
do a bare metal restore to the orig. h/w, I don't know if it can restore to different h/w.
Did you consider putting server2's HD temporarily in an external enclosure & dd
'ing server1's (80 GB) HD to it?
