Move internal HDD with HP-UX from one server to another !

[N A Khan]

Hi Friends,

We would like to take internal HDD (containg a running HP-UX) out from one server (HP9000 rp5470) and insert in another similar server (rp5470) with similar peripherals. Do you forsee any problem ? Will the HDD boot with same old HP-UX environment ?

best regards

Hi
what are the differences between them???
Becuse if I/O cards are in different slots - sorry it will not work, but if differents are in amount of RAM it will work, so be carefull.

You won't have any problems with the internal disk as long as it goes into the same slot and has the same address as the old box. Just make sure that the primary boot path matches the disk in the new system. Memory is always handled automatically. External disks, tapes, etc, will be the only concern but the system should boot OK. HP-UX will discover new addresses for peripherals at bootup and create the required device files. For peripherals that don't match I/O locations, delete the devices using rmsf. The device file names for external disks and tapes may change if they aren't at the same address so you'll need to verify those names. Use ioscan -fn (make a paper copy) on each machine and compare the results.

What about SW_ID???

Hello,

It would be a lot better if you used Ignite make_tape_recovery to archive the current system, then move the drive over to the new system, boot from the make_tape_recovery and restore on the disk. This will remove any issues with hardware instance numbers changing, differences in cpu_id, drivers etc., etc.

A little more work up front but a lot better chance at success.

Thanks for participating in the forums,

Many Thanks to you All who contributed in this discusssion.
We could do the task successfully - as we ensured the peripherals, thier quantity and location in the new server exaclty match with old server.
very best regards
