make_tape_recovery issue

Fauziah Mahdan — Tue, 10 Feb 2009 08:43:55 GMT

Hi all,
I have 1 tape drive sharing with 3 servers.
When I move the tape drive into server c and run ioscan option appear as:
Class I H/W Path Driver S/W State H/W Type Description
=====================================================================
tape 1 0/1/1/1.3.0 stape CLAIMED DEVICE HP C7438A

/dev/rmt/c3t3d0BESTb /dev/rmt/c3t3d0DDSnb

When I perform make_tape_recovery -v -I -x inc_entire=vg00 -a /dev/rmt/0m

error as

ERROR: This is not a no rewind device file.
ERROR: Check tape device failed.

The problem is I don't have option mn to choose.
Pls help.

Try this,

# mkdir /tmp/tape_backup
# mv /dev/rmt/* /tmp/tape_backup
# insf -e
# ioscan -fn tape

>> Try taking ignite backup

Hi,
Maybe is a typo, but the ioscan show the 1m tape and you perform a tape_recovery on the 0m tape.
So if you want to reinstall tape driver do what avinash write, but first check if you have the no rewind driver ll /dev/rmt/*mn

Hi,

It is always preferred to connect the tape drives when the system is powered off. If we connect the drive online then kernel may not detect the drive and leads into many issues.

First thing you need to try is reboot the system and check if all the required device files are created.

Remove the device files at hardware path 0/1/1/1.3.0 and recreate it.

#rmsf -H 0/1/1/1.3.0
#insf -e -v

Shalom,

Make sure the tape drive has power and scsi.

insf -e

Try again

Agreed that I ahve connected to the tape drive during server on.
But I have restarted the server.

What's happen now with
make_tape_recovery -v -I -x inc_entire=vg00 -a /dev/rmt/1mn

hello,

I agree with smatador. You wrote :

Where do you see a device file /dev/rmt/0m and so on ?

Hope this helps.

Make_tape_recovery still not work

Re: make_tape_recovery issue

sujit kumar singh — Tue, 10 Feb 2009 13:40:15 GMT

Hi Fauziah,

if you are using this command #make_tape_recovery -v -I -x inc_entire=vg00 -a /dev/rmt/0m

then the Ignite shall not occur because /dev/rmt/0m device-file is no more present on the system.

Instead use this command after you have loaded a media in the tape drive.

1)load the media in the tape drive properly.Wait for the Media to be stable after load and the green LED has stabilised.
2)Give the following command
#make_tape_recovery -v -I -x inc_entire=vg00 -a /dev/rmt/1mn

the reason is that the tape drive in the system now shows that this device is /dev/rmt/1mn and no more as /dev/rmt/0m.

hope i am able to point you out that correctly

regards
sujit

Re: make_tape_recovery issue

Patrick Wallek — Tue, 10 Feb 2009 13:59:52 GMT

What you need to do is use '/dev/rmt/c3t3d0DDSn'. That is the equivalent of the '1mn' device.

You command should look like this:

make_tape_recovery -v -I -x inc_entire=vg00 -a /dev/rmt/c3t3d0DDSn

Avinash20 — Tue, 10 Feb 2009 14:33:39 GMT

Hi,

As I suggested

# mkdir /tmp/tape_backup
# mv /dev/rmt/* /tmp/tape_backup
# insf -e
# ioscan -fnC tape

Re: make_tape_recovery issue

Avinash20 — Tue, 10 Feb 2009 17:03:44 GMT

From the ioscan output, after doing rmsf there are no device files available now, but the tape is CLAIMED in ioscan

Try the above commands and let me know.

I am trying to backup all the device file in /dev/rmt and then running insf to recreate the device file

Best of Luck !!

HI all,

Since I only have this option I can't perform the make_tape_recovery

Class I H/W Path Driver S/W State H/W Type Description
=====================================================================
tape 1 0/1/1/1.3.0 stape CLAIMED DEVICE HP C7438A
so I rerun another round of insf -e -v

So latest result it appear

ioscan -fnCtape

tape 1 0/1/1/1.3.0 stape CLAIMED DEVICE HP C7438A

/dev/rmt/c3t3d0BESTb /dev/rmt/c3t3d0DDSnb
/dev/rmt/c3t3d0BESTn

without /dev/rmt/1mn

so I perform this command
make_tape_recovery -v -I -x inc_entire=vg00 -a /dev/rmt/c3t3d0DDSn.
Looks like it running now at stage

What option? If you have the latest firmware, you can boot directly from tape.

Re: make_tape_recovery issue

Armin Kunaschik — Wed, 11 Feb 2009 12:07:42 GMT

This is right. Some itanium firmware releases are not able to boot from tape!

I'd suggest to use make_net_recovery, setting up an ignite server and install/maintain/recover over lan!

My 2 cents,
Armin

Ganesan R — Wed, 11 Feb 2009 12:32:58 GMT

Hi Fauziah,

If you still need /dev/rmt/1mn file, you can manually create it. It should use the same major and minor numbers of /dev/rmt/c3t3d0BESTn or /dev/rmt/c3t3d0DDSn.

#mknod /dev/rmt/1mn c 205 0x033040

ownership should be bin:bin

OldSchool — Wed, 18 Feb 2009 18:04:49 GMT

looks like you may have way more than the base OS installed in vg00.

my suggestion would be to look at /opt and identify any directories (such as /opt/IBM) that don't need to be on the ignite image. include all of vg00 and exclude the non-essential bits. those can be part of another backup tape (tar, dp or whatever)

something like:

make_tape_recovery -v -I -x inc_entire=vg00 -a /dev/rmt/c3t3d0DDSn -x exclude=/opt/IBM -x exclude=.......
