Re: 3590 Partitioning
This is an OS support and boot issue. HP has been slow to support open SAN. This ability has only been available on AIX for a little while. Paul D.

Re: 3590 Partitioning
I hadn't thought of that but in looking at my old GC35-0154-02 IBM SCSI Tape Drive, Medium Changer, Library Device Drivers (installation user's guide) I do see where the write option of tapeutil allows you to write a file. # backup ~myfile.tar~ to tape tapeutil -f/dev/rmt0 write -s myfile.tar can then read with # restore ~myfile.tar~ from tape tapeutil -f/dev/rmt0 read -d myfile.tar all sorts of useful stuff around chapter 10 (tape subcommands on pages 89-92) which is where the above examples came from. Dang-it Steve, now I'm going to have to play around with creating a tape validation script since I see the wtest rtest commands... oh well, this old dog might as well learn a new trick or two...

Re: 3590 Partitioning
Steve, a more important question (assuming these are mksysb or sysback images) -- can you boot and restore from these partitions? At D/R, will you have a good way to tell (a) which tape has the backups, and (b) which partition is system X? I feel your pain on using an entire tape for a couple of gig -- to the point that all my AIX systems now have an internal 4 mm DDS drive used ONLY for mksysb. Even at $2500 (US) per system, I didn't have much trouble selling this to management. We have a 3584 with LTO drives for the TSM library (and no SAN yet, but it is on the way this year).

Is it even possible to boot from a fibre-attached tape drive? At DR tests with a HPUX servers, it wasn't possible to use the Ignite tape in fibre-attached tape drive.
