Backup at Disk Array - HP 10.20

Ricardo Bassoi — Thu, 22 Nov 2001 11:54:52 GMT

I have a doubt in how to do a backup on my Disk Array System.
The Disk Array is an AutoRaid Model with 8 disks with 4.3 Gb each one.
I??d like to know how to backup the data inside the Array, using tape or others devices.
Thanks.

Hi Ricardo,

What sort of data is on the array. If you have filesystem information, then use any of the standard unix backup utilities: fbackup, dump, etc., or use one of the vendor solutions, e.g. Omniback, etc.

Rgds, Robin.

Ricardo,

There is no way to perform a "RAW" array backup, mainly becuase you can't restore it, so it would be a futile effort. What you need to do, as stated by Robin, do a fbackup or a tar. If it is VG00, you can do a make_recovery -Av?

hi,

the backup strategy depends on what the disks contain.
Do they have filesystems?
raw volumes?
What vg does it belong to?

Do a ioscan -nkfCdisk and get the disk paths.
Then do a pvdisplay on the disk path to
see what Logical volume it contains and take it from there.

Regarding backup, if it is Filesystem ,you can
use tar, cpio, fbackup to back it up to tape.

Hello All,

Tks by all the prompt support !
I think that I should better explain the enviroment that the system is installed:
I have 2 server working with the MC-Service Guard ( One is the Active and the other is the Standby ) and they share one Disk Array ( vgtmnpkg - 8 disks 4.3 Gb ). This share is an exclusive one ( when one server is running the other cannot mount the disk array ).
I??d like to backup this Disk Array:
-8 Disks 4.3 Gb
-1 VG ( vgtmnpkg )

Tks again.

Hi,

Why not use what you use for other backups? Perhaps you can script this so that the backup verifies the VG is activated before continuing. Or if you don't mind errors, you can just let the backup try to backup the shared VG regardless.

Back it up using the same software you would use if it was not shared.
