32-bit to 64-bit on D370

[Remy_1]

Hi,

I have a D370 machine running HP-UX 11.0, but only supporting 32-bit. Is it possible to convert it to 64-bit without a clean install?

Thanks,
Remy

Remy,

If you could, I would not suggest it, because you could end up spending more time trying to fix things. A clean install ensures that you get all of the proper libraries, utilities, and drivers needed to support 64bit.

You need to upgrade firmware on D-Class before you upgrade it to 64 bit. A clean installation of 64 bit would be ideal way to upgrade.

Agreed, 110 percent.

Have never performed an upgrade to 64 bit, always a re-install of OS & Application followed by customisation/configuration of applications. Smooth as silk every time!

If you are concerned about reversion strategy if it all goes wrong, why not ask for some new servers, then build and cutover to the new server, then cascade the servers down the line upgrading each system in turn!

Share and Enjoy! Ian

There are actually just a couple of dozen files that change for a 64 bit upgrade. It's important to inventory your I/O cards (hint: ioscan -kf) and look for EISA cards. Most EISA cards are no longer supported in 64bit HP-UX. Check the /usr/share/doc/11.00RelNotes.

Hi,

In my environment, we had a D250/1 (32-bit) upgraded to a D380/2 (64-bit).

Apart from the EISA to PCI bus migration mentioned above, there is also the graphics card you will want to take special notice of. The graphics card in my D250 was not compatible during the upgrade to D380. Both the hardware engineer and me burnt an overnight to identify the cause. No one had factored in this into the hardware requirements.

There had been other issues during the upgrade but they were fixed fairly quickly, unlike the graphics card which we had no notion that it was incompatible. The lesson learnt is that make sure you perform a complete preparation groundwork before embarking on the upgrade.

Hope this helps. Regards.

Hi,

currently I'm in need to dig out this old thread, as it describes my problem.
I have a D370/2 which only offers 32-Bit during clean installation, regardless if I'm using 11.00 oder 11.11.
What could be the reason for it?
Unsupported EISA cards in 64-Bit?

Thanks,
Ebbi

It is probably a firmware issue. I believe there is a minimum firmware version that is required for for 64-bit HP-UX.

Hmm...
I regard that as nearly impossible, as I already have the latest (last) version 42.11.
