Hello:
This may not be the right place for this so if not let me know where I
should send it.
Question:
I've got an HP 4mm DAT Autochanger here (Scsi detection shown below
from boot)...what I'm wondering is this: Is there a way to tell WHICH
ONE of the 6 tapes is in the actual tape drive from the OS? And if so,
a way to make it load a specific tape (1-6 or maybe 0-5 I'm not sure
what the numbering is) I know I can look at the LCD on the drive but
that doesn't help if I'm 90 miles away in another city trying to
tell...main reason I want to do this is after it starts to write on
tape 5 and finished there is a cleaning tape in slot 6 that I'd like
to force to load then eject the magazine so that it can get changed by
the operator next morning....if they don't see it sticking out they
forget to change it and the backup fails the next day since there is
no tape in the drive due to #5 filling up and when it loads 6 its a
cleaner which runs and unloads but obviously doesn't write data so the
job fails....does this make any sense??
Here's the boot output:
