quick question

[Greta Blamire]

I need to upgrade a R380 from 11.0 32 bit to 64 bit. I can't change the version yet. So I'm thinking do a make recovery tape with the -a option to get the full system for backup, then put the install cd in and boot from it. Is this right or is there a better way? I know 64 bit runs on the hardware, I'm in the process of getting the critical patches for it. Anything else I should do?

Greta,

We can upgrade the version from 32 bit to 64. But it seems to take more time than a fresh installation. So, you are always safe if you
take a make_recovery tape and backup configuration of your box like map files, network configuration files etc., onto another server before actually installing the OS.

I also would make sure that the make_recovery tape works by

1) Listing the contents of it by

mt -t /dev/rmt/0mn fsf 1
tar tvf /dev/rmt/0m
and
2) Booting from the tape but without installation. Interact with ISL and stop there so that you can cancel the installation anytime. So, you will get a good feel of the tape.

If you can attach an external disk or a different box, you can even try igniting the box on external disk or on another box to make sure you have a clone of the OS in place.

The above steps are just precautionary measures to make sure that you have a good backout in place.

Once the above two tests are done, you can go ahead and reinstall your R-class with 64bit.

Hi Greta:

A cold install from the Core OS CDROM, followed by the Application CD, DIAGNOSTICS, and General Patch Bundles is the most expedient, cleanest way to establish your system. I agree with your plan to make an Ignite 'make_tape_recovery' tape before you start as a fallback.

Don't forget to collect you configuration files and your 'vgexport' mapfiles onto a tape or a disk that you can easily get to them after the cold installation.

I would download the latest version of Ignite, and use it to make your before and after tapes.

Also be aware that if you have any EISA adapters you won't be able to use them once at 11.0 64-bit. There won't be any drivers available for them.

run getconf HW_32_64_CAPABLE and getconf HW_CPU_SUPP_BITS just to verify the hw capability.

There is an upgrade guide at www.hp.com/go/hpux11

Hi Greta,

to update your server to 64Bit HP-UX you must have PDC rev. 3840 or later
You can verify the PDC rev. in 2 ways:
- online: run info on a CPU when using the support tool manager (online diagnostics)
- during power up: interrupt boot process after system self test to enter PDC command mode or just monitor the console messages during bootup
