Is my box 64-bit capable?

[Barry O Flanagan]

I have a R-class (R380/810) currently running 10.20 and I would like to upgrade to 11.0 but I would like to know if my box is 64-bit capable. I believe the R-class can ship with either 32-bit or 64-bit processors?

How can I tell :
1. Which type of CPU my box has?
2. Does it matter what type of CPU I have?
3. If my machine is 64-bit capable with 11.0?

Thanks....

getconf HW_32_64_CAPABLE
will tell you

Later,

... and that returns a 1 or a 0 - I presume that a 1 is yes in this case??

sorry to be so brief, but man getconf for lots of other info on CPU and so on..
Have a good weekend,

The R380 is a system that will support 64 bit HP-UX.
The normal place to look for the information you are after is :
/usr/lib/sched.models in 10.20 or
/usr/sam/lib/mo/sched.models in 11.x

This shows the system to be PARISC 2.0 processors.

If you look in /etc/.supported_bits, you will find the R380 shows as 32/64 bit capable.
One word of warning though!!
If your system has ANY ESIA cards currently in use, you will not be able to use tham on the 64 bit kernel, as there are NO drivers for any EISA card in the 64 bit version. You would have to use 32bit to use the EISA cards.

Hi Barry:

# grep `model|awk -F/ '{print $3}` /usr/sam/lib/mo/sched.models

...will return the PA RISC levels and model you seek.

SAM's cumulative patch provides the file above so this works well on 10.20 as well as 11.0

You will see that your server supports both 32-bit and 64-bit HP-UX.

'getconf HW_32_64_CAPABLE' is not valid until you are running 11.x.
