vPar Console

Scott Buffington — Fri, 11 Mar 2011 13:30:05 GMT

I have been working with virtualization and I have some servers that were setup prior to me taking over the servers.

I have created virtual machines from scratch and now I am looking at a server that has one of it's nPars booted in vParmode. There are three vPars running under the nPar booted in vPar mode. One of the vPars seems to have lost it's network. Is there a way to pull the vPar console up like you can do with hpvmconsole for a virtual machine?

For example, when I type vparstatus all of the vPars are listed as available, but I can no longer SSH to the last vPar in the list.

(hp9-root: /:1507)-> vparstatus
[Virtual Partition]
Boot
Virtual Partition Name State Attributes Kernel Path Opts
============================== ===== ============ ======================= =====
hp9 Up Dyn,Auto,Asr /stand/vmunix
hp12 Up Dyn,Auto,Nsr /stand/vmunix
hp13 Up Dyn,Auto,Nsr /stand/vmunix

Thanks in advance.

Only a vPar on a Superdome 2 platform has a console access and can run EFI - all other platforms cannot run EFI.

The OS console is shared on the nPars console (toggle with CTRL a).

Thanks I did not know about the cntl-a toggle. I am able to see the console prompts for each vpar.

It seems the vPar is non-responsive for some reason, I get a login prompt at the console but no response when I enter my login and press the enter key. I can successfully login to the other vPars.

Am I able to utilize the vparreset command on this vPar even though it is in an upstate? Thank you.

yes you can, simply go onto a running vpar and use the vparreset command to reset that vpar

Shalom,

parstatus will give you some more information.

I think vparreset once on console will get you where you want to go.

These are available from web based or network console.

ctrl-b is the key command to bring up the interface once connected.

Since you are using ssh, I'm assuming modern hardware, Itanium with EFI

vparstatus -A

Also a handy tool showing available resources in case you need more networking or fiber for your new or current vpars.
