dd an ignite backup to disk. (hpvm os backup)
The vpars are basically lv's on the host machine.
I'll backup up the host machine with a network ignite.
I would set up a ignite server on the host, but I can't have nfs turned on, unless it's encrpted. And I don't think secure nfs is support until hpux 11i v3. We're going to be running hpux 11i v2.
Is it possible to recover vpar OS's by coping a make_recovery image straight to disk with dd?
My next option would be to shutdown the vpar then dd the vpar lv out to a file, then I should be able to recover the os by dd'ing the file back out to the lv.
for ex: dd if=/dev/vg00/vpar01 of=/vpar-backup/vpar01.img bs=?

You can use make_net_recovery (requires NFS) or make_sys_image .
make_sys_image makes ignite images and can go to local disk.

Re: dd an ignite backup to disk. (hpvm os backup)
I'm sure you are running HP Integrity virtual machines (HPVM), but this is NOT vPars!
The recommended backup procedure is ignite.
A "dd" might work, but you need to test this.
Hope this helps!
Regards
Torsten.

At the other hand, what is the problem ? If you can dd the tape to disk, you can probably use it also with ignite recovery.
If you have no direct tape-boot available, boot from the installation CD and read the recovery tape from there.

I'm trying to avoid having to turn insecure services on my (hpvm) host server.

Re: dd an ignite backup to disk. (hpvm os backup)
If you don't want to use ignite via network, consider to use a tape and do make_tape_recovery from the guest.
Hope this helps!

Re: dd an ignite backup to disk. (hpvm os backup)
if you have the VMs in a logical volume and can shut them down, it should be safe to use dd to backup the *raw* lvol to another disk or into a file or on a tape and to restore from there into the original rlvol.
you should use a blocksize of 256k or larger.

Bernhard
