Forcing 64bit 11 install on K570

[Mike Seerden]

Ok, I originally installed HP-UX 11 from scratch. It installed as 32bit. I posted here and followed some suggestions on upgrading the OS to 64 bit. Nothing worked. So I am going to reload from scratch again. The system is a K570 with 200MHz PA8x00 chips. The firmware is above recommended levels for a 64bit install. Now the question. How do I make sure it loads 64 bit during the install instead od 32bit. Thanks for your help.

As far as I know , K570 supports both 32 and 64 bit Hp-UX OS. So when you start the install you should get the option by default to select either 32 or 64 bit HP-UX 11 . This is just in the second or third menu I guess.
Hope this helps.

The install process will present you with a choice of 23 or 64 bits aas long as the hardware identifies itself as 64-bit capable. The 570 is certainly 64-bit capable. However, if the 64-bit choice is missing, then the processor ROMs have not been setup correctly, perhaps due to a previous repair that wasn't completely finished.

K570 does support installation of 32 and 64 bits OS.
(see file /etc/.supported_bits)
But this file seems to no more exist in HP-UX 11i.
So, another way to check it, is to execute :
# getconf KERNEL_BITS
32/64

But some CPU need a firmware update to support 64 bit OS.
If you type :
# getconf HW_32_64_CAPABLE
and it returns "2" : 32 bit only capable !
it returns "3" : 32 AND 64 bit capable !
In the first case, you might need a firmware update (see patch database)

Another getconf command that may be useful is...

getconf HW_CPU_SUPP_BITS


it will display a 32 or 64...this represents what the CPU will support...

Mike,

We recently went through the circle of trying to load 64-bit UX 11.0 onto two K460's. During the OS install we only had the choice of 32-bit. We found that one system was an 800 series instead of a 889. To check your system, do a uname -a. It must ID as a 9000/889 to run 64-bit. If it isn't 889 and you have H/P Hardware contract, they can upgrade the system ID, through configuration software.
