I've got a Sun Blade 2000 with Solaris 10 update 5. It has a pair of
internal 137 GB SCSI disks (FC-AL) which are not mirrored and a pair of
1 TB USB external drives which are mirrored to create a single 1 TB
volume (actually 914 GB, but that is marketing for you).

Is it possible to create snapshots of the SCSI disks (which I intend
using for most tasks) and putting the snapshots onto the
cheaper/slower/larger USB drives?


The SCSI disks are close to full capacity, so I am not going to get many
snapshots on them, whereas I have tons of space on the pool made from
the external USB disks.
