ontape back-up/restore to remote device

I'm running OnLine 7.13 on Solaris 2.5. I'm playing around with back-ups to a remote DLT. I'm a bit green in this area as I usually do back-ups to disk. On UNIX server ubrs04 In my $ONCONFIG I have TAPEDEV set to ubns07:/dev/rmt/0n. All the rsh set up is OK, and an ontape -s writes happily to the remote DLT on ubns07. When I come to do a restore with ontape -r, the header information is read back correctly from the tape,but then the restore fails thus: Continue restore? (y/n) Do you want to back up the logs? (y/n)n Physical restore failed - function read archive backup failed code 1 errno 0 Does anyone know why, and what can be done? I'll be quite happy to be put out of my misery with a succinct RTFM - plus page reference! Thanks Neil Truby Chase Manhattan Bank Bournemouth, UK neil.truby@chase.com
