how to backup up a HPVM Guest OS

[yokus]

hi,all
I　using the DP to backup the file,now I hope to backup a HPVM guest OS to the tape and then restore the HPVM.
can anyone show me the tips?
best regards.

[yokus]

I want to use the DP to backup the files,
but I don't know which file have to be backup?

[Torsten.]

Why not backup the guest directly from itself like a "normal" system?

[yokus]

Torsten,thankyou for answer this question.
I backup the backing store files which under
/myhpvm/vg00/
it including the following file and directory:
vm1.vdk
lost+found
my guest os was install on the vm1.vdk.

when I restored these file,I recreated a HPVM,
and using the following command to add vm1.vdk
$hpvmmodify -P vm1 -a disk:scsi::file:/myhpvm/vg00/vm1.vdk

and then I restart the HPVM
$hpvmstart -P vm1
it is nice but my hpvmstatus tell me that
ON(EFI)ï¼ it indicated me that the OS didn't boot successfully.

what should I do now?

[Torsten.]

I would ignite the guest system like a "normal" system.

[yokus]

Torsten,thank you again.
your opinion is right.
but our customer will face more than 50 guest
OS and they hope the the backup can be outside
the guest OS ,which means they don't want to
use the make_tape_recover or ignite ,or just
make a snapclone /snapshot at their EVA which
storage the guest os's disk.

To backup the OS i would let Ignite do it.

make_tape_recovery if you've got a tape drive, or make_net_recovery if you have two separate systems to configure as Ignite Server and Client.

I agree, make_net_recovery is made for this.

thank you,but my customers only allow using the DP.
so I have to keep on finding the solutions.

[Marcel Burggraeve · Accepted solution]

Personally I would really try to convince the customer to make an ignite backup as well.
Besides that I would also make a normal file backup making it easier to restore seperate files if needed.

Do you shutdown the guest when you make this backup ?
I guess as long as the guest is running you're basically making an open file backup.

Basically this is just the same as people who only backup the vmdk files of a vmware esx server :-)
Same kind of discussions going on there.

[yokus]

thanks Marcel
you are deeply right.
it should shutdown the guest before you backup,I did it before I backup.

But still I fail to boot the guest os,I added the log file to yours.please kindly to have a look.

the main reason I think it is the following warning:
----------------
System Console is on the Built-In Serial Interface
WARNING: ROOT device 0x1f010002 is a non-LVM partition, disallowed on LVM disk.
WARNING: ROOT device 0x1f010002 has been deconfigured (set to 0xffffffff).
----------------
by the way,I can boot the system with the mode:

$hpvm -lm

I am wondering if I need to converse this non-lvm boot disk to LVM boot disk.

but first,please tell me the collect way to backup and restore a GUEST OS.
thanks all

In my humble opinion you can't backup HP-UX with DP. If it was Windows, you would have got a chance. But HP-UX - forget it.

Even if you are that goog and succeed to hack the code to get it working, remember you will be doing it the unsupported way, so you'll have to forget you can get help from HP support if your HP-UX crashes.

They called it Dataprotector for a reason, and not OSprotector. That's why they developed Ignite-UX. And I don't see a reason why your customer wouldn't agree to use Ignite. It's a free software.

I've seen this error before on Itanium systems and haven't found a solution yet.
However, that was without HPVM involved.

In short when I've seen it :
From a running OS we create a new VG including all logical volumes.
From a previous made full backup with fbackup ( written to disk ) we restore the OS to the new VG.
With this procedure we're able to create a clean test system really fast.
This used to work for all HP-UX versions starting at 10.20 and ending at 11i V3.
VG's created with 11i V3 and being used to restore 11i V2 will give the same error you just showed in the attachment.
