I understand that the superdome I have is conected to HP EVA for OS,app disks and XP12000 for data.

I need to understand the above output..

When asked, I can provide the information here..I want to know about the cellboards, cores,.max amount of memory in a cell, CPU and core relations etc..
Thank you very much.

Hi,
you can start with parstatus command.
# parstatus

Check the man page.

[Torsten.]

The virtual USB bus is always present, even if there is no USB.

Don't worry about this - just ignore.


For the other questions you should read the owners manual available from hp.com/go/bsc

I followed this path:

Discover and use a product
HP Integrity servers
HP Integrity Superdome SX2000 Servers

Not sure what to look out for here...

As I said, I like to understand my superdome better. I have access to login into it.
It has a few nPars and vPars.
I want to understand how they have been built etc etc.

to start off....
How can see the firmware version of my superdome?

Turgay
attached the parstatus output
nPar1 and nPar2 have 11iV2
nPar3 and nPar4 have 11iv3
vPar-rac1 and vPar-rac2 each have six vpars in them(a few vPars have 11iV2 and other have 11iV3 too)

In the output of parstatus, you can see cell/cpu/ram configs. You have 8 cells, each cell has 8 cores and 64GB RAM.

To see firmware revision you have to log on MP, in the command mode use "sysrev" command.

Shalom,

Quick summary for those who dislike documents.

superdomes are paritioned in layers.

On the hardware layer, you assign cells to a hardware partition, called an npar.

On a software layer you actually have two choices. You can build HP-UX systems with vpar, and you can build Linux, Windows and HP-UX systems with hpvm technology.

Pretty cool actually.

Your best bet is to NOT use the shortcut but to read enough how Cell Based servers work.
I also found below link quite useful but give it enough time to read and visualize:

docs.hp.com/en/B2355-90702/B2355-90702.pdf

"How can see the firmware version of my superdome?"
----->Go to MP->Command Mode and enter sysrev

I will read of your links, docs, login and see for my self and comeback again in a couple of days. Thank you.
