How to configure/deconfigure CPU's online on rx7620 HP-UX 11i v2?

[Luk Vandenbussche]

Hi,

Why do you need to do this?

At harware failure CPU gets automaticly deconfigured.

At vpar level you can move a CPU online if it is not bound.

Can you give some extra info please.

Hi,

I think this only possible if you use vpar ot prm software otherwise cpu's can be configured in the efi shell command (not online)

Hope this helps,

should be npar.

Cell hot-plug
The HP Integrity rx7620-16 and rx8620-32 Servers support cell hot-plug. Coupled with the serversâ partitioning capability1, cell hot-plug allows for the servicing of cell boards within a single partition while the other partition continues normal operation. Any number of configuration changes can be made to the partition being serviced, including replacing the complete cell board, adding or deleting CPUs and memory, or even increasing or decreasing the number of cells in that partition. (Cell hot-plug is supported only in systems with two or more partitions.)

[Torsten. · Accepted solution]

config/deconfig is made during boot. But you can allocate/deallocate a CPU online, this means no process will run on that cpu if it is deallocated. You can allocate/deallocate or mark for configure/deconfigure (will happen on next reboot) using work load manager or diagnostics. But also the system is able to mark CPUs deconfig if an error orrured.
As mentioned above, in a vPar environment you can add or delete CPUs to/from a vPar, it's just like allocate/deallocate in a non-Vpar environment.
