Hi:

You could probably do:

# mt -t /dev/rmt/0mn rew

...and examine the return code ($?).

when i run the mt -t /dev/rmt/0m rew command, getting output like

mt -t /dev/rmt/0m rew
/dev/rmt/0m: No such device or address
# mt -t /dev/rmt/0mb rew
/dev/rmt/0mb: No such device or address

Hi (again):

> when i run the mt -t /dev/rmt/0m rew command, getting output like

/dev/rmt/0m: No such device or address
# mt -t /dev/rmt/0mb rew
/dev/rmt/0mb: No such device or address

First, use a Berkley, no-rewind device, like '/dev/rmt/0mnb'.

An 'ioscan -kfnC tape' will show your available tape devices.

You need to substitue the correct device file for your tape device. You can find this with the "ioscan -kfnCtape" command. The most common mistake is typing the letter O (oh) instead of 0 (zero). I can't tell from your posting if maybe that's what you've done or not.

ioscan -fnC tape

mt -f /dev/rmt0mn rewind

for more information (man mt)

Hi,

First do (to know about the tapes in the server)

# ioscan -fnC tape

then, with the correct device name, perform

# mt -f /dev/rmt/?mn rew

# mt -f /dev/rmt/?mn stat

where ? should be replaced with your correct tape drive name.

1) "mt -f /dev/rmt...." note that at 10.20, the "status" command wasn't available. It was added to 11.0 with later patches, and should have been there out of the box with current OS releases

2) can you read or write /dev/rmt/0mn with something like tar?

what does "ls -l /dev/rmt" show?
