SSSU / Unix scripting for snapshots. HP-UX & EVA3000

[David Fanning]

Hi All,

We have an HP-UX server with Virtual Disks presented to it by an EVA3000.

I need to write an SSSU / UNIX script to run each day to:-
- Delete perious days snapshot(so that it's not seen by the EVA or Unix)
- Pause Database
- Flush the Unix cache
- Take the Snapshot
- Present snapshot to the Unix server
- Resume Database
- Unix commands to mount /make available the snapshot
- Backup the snapshot to tape.

Could anyone help with some example scripts with the appropiate SSSU and UNIX commands to get me started.
Any help would be much apreciated.
David.

I don't have any scripts, but you better create the new snapshot and then trigger the deletion of the old one.

David,
First of all i want to say that what you are talking about just really complex but probable...
Last year, i realized it with my HP support
:-))
and nowadays i will modify it (because i
want to do some advance tests)
when i finished then i really promise you
to realize it on your env.
i can not send these scripts now because
first i have to test...
so keep this thread open you may also received some best solutions from the other
members who did it and still use.
Good Luck,

Hello David,

I include some fragments of scripts that you need.

to delete vdisk

SELECT MANAGER SWMA1 USER=administrator PASSWORD=administrator
SELECT SYSTEM "EVA1"
DELETE LUN "\Hosts\unix1\10"
DELETE VDISK "\Virtual Disks\data\snap_vdisk1\ACTIVE" WAIT_FOR_COMPLETION

you have to set up your Data Base in begin backup mode before start the snapshot.

to create snapshot

SELECT MANAGER SWMA1 USER=administrator PASSWORD=administrator
SELECT SYSTEM "EVA1"
ADD SNAPSHOT snap_vdisk1 VDISK="\Virtual Disks\data\vdisk1\ACTIVE" DISKGROUP="\Disk Groups\snap"
ADD LUN 1 VDISK="\Virtual Disks\data\snap_vdisk1\ACTIVE" HOST="\Hosts\unix1\10"

I expect this information can help you to built the script.

Goor Luck.

I confirm that the SSSU part is fine because I used to use it on Solaris systems. However I have problems to mount the snapshot on an HP-UX system...


It's telling me 'vxfs mount: /dev/vg09/snapshot is corrupted. needs checking'
