Mounting DLT Tape...

[Hazem Mahmoud_3]

I'm having trouble mounting a DLT tape to perform a Veritas restore, can someone give me the syntax. A bunny for whoever helps me here! Here is the error I get:
# mount /dev/rmt/0mn /tmp_mnt
mount: /dev/rmt/0mn is an invalid operand

Below is the ioscan output:

# ioscan -funC tape

Here is what i get:
# mount -ro /dev/rmt/1mn /tmp_mnt
mount: /tmp_mnt was either ignored or not found in /etc/fstab

Depends on how the tape was created...what tool created it? Netbackup/omniback/fbackup?


fbackup/frecover
frecover -rNv -f /dev/rmt/0m > /tmp/listing


or Use Omniback if you have that tool can tell you a lot about the tape

[Hazem Mahmoud_3]

Netbackup.

Then you can use the Netbackup gui or command line to restore the data you wish...

Of course you must have Netbackup loaded on your server.

Thanks, I'm just going to use fbackup/frecover instead of Veritas. It's too complicated for what I need to do:) Thanks for your help though!

I have the same problem, I cannot mount tape. I tried the mount -ro /dev/rmt/0m and got the invalid operand. I looked at the script, it was done with a tar command. I tried tar -tvf to look at it. It hung. Any ideas how to mount? Thanks.

You do NOT mount a tape with the mount command. It just isn't possible.

To restore from a tape, you put the tape in the drive and then run whatever the appropriate command is to restore.

If your tape drive is /dev/rmt/0m and the tape was created with tar, then you do:

1) Put the tape in the drive. Wait until the light turns green and the tape is finished loadking.

2) Do this command:

# tar -tvf /dev/rmt/0m

If it doesn't respond or errors, then a) the tape was not created with tar, or b) your tape is messed up and you have very little hope of restoring.
