vg00 backup

Hi All!

I have rx7620/rx8620 and rp servers. We use SAN with a tape library msl5000. How can i make a recovery tape for all the vg00(s) with this library.

Thanks

Hi Kingsley

At first check tape by

#ioscan -funC tape

Then backup full vg00 by below command

# make_tape_recovery -a /dev/rmt/?mn -I -v -x inc_entire=vg00

Hi Kingsley,

First check the tape libraray by:

#ioscan -funC tape

For the full backup of vg00 use:

# make_tape_recovery -a /dev/rmt/?mn -I -v -x inc_entire=vg00

Re: vg00 backup

Hi Kingsley,

First check the tape libraray by:

#ioscan -fnC tape

For the full backup of vg00 use:

# make_tape_recovery -a /dev/rmt/0mn -I -v -x inc_entire=vg00

If u intend to use a tape drive other than the default (/dev/rmt/0m), modify the command to point to the device you want to use, for example, a tape drive at
/dev/rmt/3mn:

# make_tape_recovery -a /dev/rmt/3mn -I -v -x inc_entire=vg00

Re: vg00 backup

Taking a backup is one thing, restore another one. You need a bootable tape in order to perform system restore and I am in doubt whether you can achieve this with a fibre-attached library.

Re: vg00 backup

You can put a tape into a drive and do a backup.

In case of restore, you need to boot from an install DVD first, in order to reach the fiber attached tape drive.

Hope this helps!

Re: vg00 backup

Hi Kingsley,

you can use the msl library to create a recovery tape, but you can't boot from the msl library so you will not be able to recover from the tape.
Consider setting up an ignite server. You can then create recovery archives for all your machines on disk and recover from them over the network.

Re: vg00 backup


Dear kingsley

u need ignite backup for the vg00 because it contains root file systems boot files etc..
so my advice please separate media for the back up etither tap or cd etc..
far better is please take in a tape.


thanks and regards

Re: vg00 backup

you can make a tape recovery on a We use SAN with a tape library msl5000, but I do not think this is usable for a bootable backup, du to that the tape library msl5000 will properly wil not have the drivers in "single user mode"
The best solution is to make the botable backup on disk just make sure you are not backing up the ignite server on the ignite server.... the ignite backups that are written to disk will work if a restore is needed... (if the setup is done fine.)

Re: vg00 backup

Hi,

please follow the steps :--

(1)kmsystem -q stape ( To check tape driver configured in kernel)

(2)Attach a tape
#insf -e

(3)ioscan -fnC tape (check the tape path /dev/rmt/xmn)

Best practice method, stop the SAP appln then

(4) /opt/ignite/bin/make_tape_recovery -x inc_entire=vg00 -I -v -a /dev/rmt/xmn ( To take the ignite backup of root vg)

Re: vg00 backup

Assuming you tape library visible to the unix boxes you can do a ignite and ensure vg00 is backed up.

man make_tape_recovery for the relevent switches.

make_net_recovery can be used for remote ignite backups if you have ignite server configured

Re: vg00 backup

Taking Ignite backup can be done, but you need to ensure that the recovery is supported.
