Ignite from L2000 on L1000

I have an L2000 running HP-UX 10.20 (I can't upgrade for application support reasons). In the event of a disaster I have a spare L1000 that I would like to restore an Ignite backup on to. Will there be any compatibility issues doing this as the machines are different?

Hi,

It should work if you don't have non-standard cards (network, SCSI) in L1000, but in any case it's worth to check. 8)))

Hi Ian,

If I remember correct, the first L-class was both 32 and 64 bits capable, later models included a firmware version making the L-class 64 bits only.

If your L2000 is running 10.20 you should first have a look at the firmware and compare that revision with the firmware revision on the L1000.

Have a look at below document.

If you are running 10.20 I do not think 64-bit would exist in the equation.

I vote that this should work find,( all disclaimers apply due to the age of the OS ).

Your best bet is to just try it.

Hi
As say Victor, you must test your restore before a possible crash, you and your boss 'll can sleep better after ;)
Except a pbs on /dev/dsk names files whose are different with /etc/checklist it should work.

Cloning a model to a different one with a recovery image can be tricky, but these are close enough that it should work OK.

As with most ignite tasks, try it and see.

Re: Ignite from L2000 on L1000

L2000 with 10.20 - unlikely!
run
# model
# uname -a
and post!
General advise:
take a backup, restore to the other system, adjust the IP and test - you will be sure.

Hope this helps!
Regards
Torsten.

Re: Ignite from L2000 on L1000

Torsten already replied by saying unlikely to a L2000 running HP-UX 10.20 but it's better to call it impossible.
L-Class systems run HP-UX 11.00 and higher (not the latest 11i v3 though) and certainly not 10.20
I think it's best to check first what type of system(s) you have exactly and make really sure which HP-UX you're running.

Re: Ignite from L2000 on L1000

you have a special L2000 ore a special 10.20 version, because normal L2000 can not run 10.20...
To check if you 10.20 version is on 64 bids please run:
getconf KERNEL_BITS
to check if you have a special L2000 that can run 32 bids please run a
/var/opt/ignite/local/host.info
If you do this on your L1000/L2000 class and it shows can_run_32bit=TRUE

It shoult be save, testing is ofcause always the best way to sleep ok....

Please post the
/var/opt/ignite/local/host.info
of the two nodes?

Re: Ignite from L2000 on L1000

Thanks for your help.
I agree that the only way to be sure is to try it out and that is what I plan to do. I just wanted to check beforehand that there were no show shoppers that would mean I was wasting my time.
As for the L2000 on HP-UX 10.20, I need to check that out. I do not have access to the servers at the moment and was just going on what I was told was running on the box. I guess I shouldn't be so trusting in the future.

Re: Ignite from L2000 on L1000

If you don't know the type of both systems involved you're still risking a showstopper and wasting time by just trying.

Suppose the 10.20 system really exists and it's let's say a D or K-Class.
Let's also suppose the other system really is a L1000.
Just like the L2000 the L1000 is not capable of running 10.20 so you would still be wasting time....

If you want to know beforehand how big a risk you have of wasting time you need to know at least what kind of systems are involved.
