• PCI OL* (On-Line Addition and Replacement)

Except for the function stated below, OL* for PCI slots works the same on a vPars server as it does on a

non-vPars server. Note that you can execute PCI OL* functions only on the PCI slots that the virtual

partition owns.

PCI doorbells (the physical attention button on the system) are supported beginning with the HP-UX

December 20003 HWE release and vPars A.03.01.

(PA-RISC only) In a vPars system, a reboot of the virtual partition does not power on a slot that was

powered off prior to the reboot. If you wish to power on the slot, you need to power on the slot manually

after the reboot using the rad command: rad -i

slot_id

For changes in the use of OLAR on HP-UX 11i v2 (11.23), please see the 11.23 OLAR documentation at

http://docs.hp.com.

• Support Tools

For information on the required version of the Support Tools package that can run on your vPars server,

see the section on Online Diagnostics in the HP-UX Virtual Partitions Ordering and Configuration Guide.

Prior to STM version A.43.00 (December 2003), in a vPars environment if the LPMC (Low Priority

Machine Check) Monitor (now known as CPU Monitor) of the Support Tools bundle deactivates a

processor, it does not automatically replace the failing processor with an iCAP (formerly known as iCOD)

processor. The processor replacement must be performed manually using the icod_modify command.

For more information, see the manual titled Instant Capacity User’s Guide at http://docs.hp.com.

Beginning with STM version A.43.00, in a vPars environment, the LPMC monitor automatically replaces

a failing processor with an iCAP processor if an iCAP processor is available.

CAUTION CPU Expert Tool is supported on vPars servers. However, using this on vPars servers may

cause unpredictable results. For complete information on using the Support Tools with

vPars, see the Support Tools document:

• CSTM’s CPU Info Tool

With STM version A.43.00, the CSTM's cpu info tool will show information about the bound processors

assigned to that partition and unbound processors not assigned to any partition. For unbound procesors

assigned to other partitions, it shows N/A.

With STM version C.48.00 (HWE0505) and later, the CSTM's CPU info tool will show information about

all the CPUs that are assigned to the current partition.

When using cstm’s info command, information is shown only for the processors that are currently owned

by the virtual partition from which the info command is run. For the CPUs which are not assigned to the

virtual partition, the information is displayed as N/A.

• ODE Diagnostic and IO Card Utilities (Integrity Only)

ODE diagnostics utilities, such as CEC, CPU, or MEM, will not operate in vPars mode. Also, the IO card

and diagnostic utilities, such as FCFUPDATE and IODIAG.efi, will not operate in vPars mode.
