Real time status of tape drive loaded for backup
Do we have a way in solaris to actuallyu check in real time the activity of a tape when it is loaded for backup?

I know mt -f /dev/rmt/0n stat will provide the status. If it's busy, meaning it's currrently on backup mode or someone is using it (fuser -u /dev/rmt/0n)

I wanted to check if the backup is ongoing or if there's an error because there are times when my backup is super long which I assumed that there's something happening on the tape (maybe hanging oe something else)

thank you

you can check the activity on the TAPE DRIVE by following command :

Quote:
# iostat -xn 5|egrep '%|rmt'
r/s w/s kr/s kw/s wait actv wsvc_t asvc_t %w %b device
0.0 6.5 0.0 1434.6 0.0 0.0 0.0 3.8 0 2 rmt/0

0.0 80.8 0.0 41384.0 0.0 0.6 0.0 6.8 0 55 rmt/0

In above example 4th col. is the speed of the drive.

Thanks.
