Unable to use cstm on a HPVM

[Daniel Hadland]

Hi, I'm trying to use cstm on a HPVM (11.31) running on an rx8620 host (11.31) and HPVM 4.0.

I can run cstm and get to a prompt however when I run cstm>info I get the following message:

cstm>info
^-- (Information) is currently disabled. --

Does anyone know if this just a limitation of using VM's?

Thanks, Dan

Do you mean in a VM guest?

So cstm is an interface to the hardware diagnostics.

HPVM is a fully virtualised environment. You would never want to look at hardware diagnostics in a VM guest.

On the VM host it should work though. You have to select a device first though. If you just run csrtm and type info you will get vthe message you see.

Determine what device you want info on from the map command and then select it using the "sel dev n" command when n is the device number reported by map.

Then run info, and if there is an informational tool for it, you should see it running when you re-run map

Hi Duncan,

Thanks for the reply. Yes I am trying to run it on the VM having identified the device etc, guess the hardware doesn't get virtualised to the extent that cstm would see it.

Thanks for the help,

Dan,

See the manual:

http://docs.hp.com/en/T2767-90141/ch01s05.html

Specifically:

-----------------------------
Do not run the following types of applications on a guest:

-Integrity VM software

-Hardware diagnostic tools and support tools (should be run on the VM Host)

-----------------------------

Thanks for the pointer, answers my questions :)

I know it is not support, but I need to try it anyway - just to see it is not useful.

# model
ia64 hp server Integrity Virtual Machine

# echo "sel dev all;info;wait;il"|cstm

You can see some virtual devices, but there is no really useful information (as expected). I would be surprised to see any real errors in virtual devices ... ;-))
