Ill keep it brief, I have an HP Ultrium 1 in a server currently running CA ArcServe r11.1.
I have 5 daily backup tapes, each of which are new. 3 of the 5 work fine without intervention but 2 of them stop at varying points through the backup asking for a new tape, even though that tape is not full. The way I have found around this is to switch the tape drive offline for 10 minutes then switch it back online, whilst the backup is still running.
Has anyone ever seen this before? If so, any ideas how to permanently fix this.
If all else fails just some pointers in the right direction.
