I've used several tape autoloaders during my professional life. I
recall that we can use ufsdump or tar or dd with at least some

whenever I tried it.
I'm planning to try this with a new Quantum Superloader 3 with LTO5
tape drives and zfs send. I need to migrate a Solaris 10 host on a
V440 to a new SAN. There is a 10 TB zfs pool & filesystem that is
comprised of 3 LUNs of different sizes put in the zfs pool, and it's
almost full. Rather than copying the various sized Luns from the old
SAN storage unit to the new one & getting ZFS to recognize the pool, I
thought it would be cleaner to dump the zfs filesystem to the tape
autoloader & restore it to a 10TB Lun. The users can live without
this zfs filesystem for a few days.
Why can't you just send directly to the new LUN? Create a new pool,
send the data, export the old pool and rename.
