Thanks a lot, glad you liked it :)

Yes I agree, using older, slower disks in this way for backups seems a nice way 
to reuse old kit for something useful.

There's one nasty problem I've seen with making a pool from an iSCSI disk 
hosted on a different machine, and that is that if you turn off the hosting 
machine, if you then shutdown the machine using the iSCSI disk in the pool, it 
takes ages to shutdown. Seems like it tries forever (or a long time anyway) to 
connect with the iSCSI disk and finds it can't, obviously. I think there's a 
bug report for this, and I thought it was fixed but, as of SXCE build 85, it 
seems not as I saw the problem occur again yesterday.

The solution is to do a 'zpool export pool_importing_iSCSI_disks' before 
shutting down the machine and then it will shutdown normally without trying to 
connect to the iSCSI target(s).

This guy seems to have had lots of fun with iSCSI :)

I wonder how many of his problems were due to using a non-Solaris iSCSI target? 
My experience of mixing iSCSI targets & initiators from different OS's was not 
very good, but I didn't do very much with it.
