but at last it is showing below error,

You don't have a device file named

/dev/rmt/0mn

Your drive C5683A doesn't have a device file like x_mn at all, so I would try to remove and re-create the device files for H/W path

0/0/1/1/1.1.0

using rmsf -H ... and insf -e -H ...

Shalom,

You direct the job to tape device /dev/rmt/0mn

No device by that path/name exists on your system.

Try /dev/rmt/2mn

Hi Ahmad,

Since you do not have the device file /dev/rmt/0mn, use the below command,

#/opt/ignite/bin/make_tape_recovery -Av -a /dev/rmt/2mn

or

Create the device file at hardware path 0/0/1/1/1.1.0 as Torstan speficied.

Hi,

You have spotted your mistake correctly.
You do not have tape drive with device name as 0mn - It seems you have 2 drives.
1 - DAT drive (0/0/1/1/1.1.0) and other is LTO 2 drive (0/0/10/1/0/4/0).

Ideally there are some more device names like /dev/rmt/1m , 1mn , 1mb and 1mnb associated apart from the BEST and DDS names. - not sure why they are not appearing in your case.

But you can tyr using the device names shown in your ioscan - /dev/rmt/c1t1d0DDS for the DAT drive or /dev/rmt/2m for your LTO2 drive.

Ninad

Hi,
You have 2 tape drives in your server,
But, the device file you specified in the command is not pointing to any of the device.
You can try # /opt/ignite/bin/make_tape_recovery -Av -a /dev/rmt/2mn
The command will take ignite backup on your second tape drive (2 0/0/10/1/0/4/0.1.29.255.0.0.0)

If you want to take backup on your first tape drive, first you have to create the device files. Follow the steps given by Torsten.
#rmsf -H 9 0/0/1/1
#insf -e -H 9 0/0/1/1

Then find the corresponding device file name from ioscan, and take backup.

i tried to recreate the device file, but the device name doesn't changed. i also tried with below shown location "/dev/rmt/c1t1d0BESTn", but it again failed with the same error.

kindly suggest.

Hi,

Have you removed the device files, using rmsf? If not, please remove, and then recreate.....

hi, i have removed and recreated the device file but still the tape drive name doesn't changed.

[sreekanthtm]

Hi,
Can you post the o/p of # ioscan -fnC tape
because ioscan -kfnC will show the cache.

and what about the other tape drive? Did you tried with that??

Meanwhile you can try this:

# /opt/ignite/bin/make_tape_recovery -Av -a /dev/rmt/c1t1d0BESTn

Please post

# ll /dev/rmt

The existing device files in /dev/rmt and your devices don't fit together.

I would try to manually delete all the 0m* 1m* and 3m* file and try "insf -e -C tape" again.

[sreekanthtm]

Try this

# /opt/ignite/bin/make_tape_recovery -Av -a /dev/rmt/2mn

What error msg you are getting here??

Since the DAT drive is to be used for the ignite backup - pls try using /dev/rmt/c1t1d0BESTn device.

Yes After changing the Drive path backup was completed.

Thanks everybody.
