Doing an image backup on VMS5.1? Watch out for this GOTCHA!
$ backup/image disk tape
$! you fill up three tapes for one disk
$! you remove the write rings just to be safe
$ backup/image tape disk
$! at the end of restoring the first volume you get:
$! %SYSTEM-I-IVCHAN, invalid I/O channel messages by the thousands
$! you take out your sledge hammer and operate on the hardware
Solution? LEAVE THE WRITE RINGS IN THE TAPES!
Don't ask me why, but standalone backup wants write
access to that tape. Any comments from other poor souls
who have seen this error? Is it fixed in VMS5.3?

Are you doing a standalone-backup, ie. shutdown the system and reboot a standalone-vmb (micro-vms) OR are you doing an image-backup on a running system. I must say I've *NEVER* seen BACKUP behave like this. -------------------------------------------------------------------------------- Flemming Jensen UUCP : dafj@vaxa.aud.auc.dk University of Aalborg (AUD) Internet : dafj@vax87.auc.dk Fredrik Bajersvej 5 Telephone : + 4598158522 - 4032 9200 Aalborg 0 Telefax : + 4598117016 DENMARK X.25 : 238302121245:dafj --------------------------------------------------------------------------------
