HP Superdome 2 Partitioning Administrator Guide (5900-2540, December 2012)

When any of the 2-letter equivalents for POWERON/POWEROFF/TOC/REBOOT (namely, pe, tc, and rs respectively)

are executed without any arguments, a list of available partitions on which the command may be excercised are displayed.

POWEROFF PARTITION

From the CLI

• Command:

POWEROFF PARTITION {{nPartition number or name} [:vPartition number

or name] [FORCE] [OVERRIDE] | ALL [FORCE]}

• Description:

Gracefully shuts down any OS running on the specified nPartition or vPar and brings it to an

inactive state. The active blades and IO interconnects in the nPartition are powered off if the

specified target is an nPartition.

The OVERRIDE argument shuts down all virtual partitions in the specified nPartition.

CAUTION: The POWEROFF PARTITION ALL command requires the FORCE argument and

ungracefully shuts down all partitions. This can cause a partition to lose data and possibly

become unstable. On the other hand, if a partition is at EFI, the FORCE argument is required

to shut it down.

NOTE: An OVERRIDE option is required to affect a change in mode or when a destructive

operation needs to be applied to all vPars in an nPartition. HP Superdome 2 partition

management supports two modes of operation for an nPartition: the “nPars” mode and the

“vPars” mode. The mode is an attribute of the nPartition. When in nPars mode, an nPartition

normally boots up as a single OS instance (or HPVM host). When in vPars mode, an nPartition

normally boots up a set of explicitly defined virtual partitions, each running its own OS instance.

The mode of operation can be switched between the two using partition CLI commands and

takes effect only when the nPartition is rebooted.

When in nPars mode, vPar definitions may or may not exist; they are not used if they do exist.

There are some deviations from the normal policy in certain scenarios to facilitate a better

customer experience. Normal behavior is to disallow vPars operations when in nPars mode

and to disallow nPartition operations when in vPars mode, unless the command is given with

the OVERRIDE option. The OVERRIDE option works only when the nPar is in RUN_VPARS

mode. If the nPar is in EFI state and the mode is changed to vPars, OVERRIDE option must

be given. If the nPar is already in RUN_VPARS mode, then OVERRIDE option is must. For

example, if an operation is targeted at a vPar while in nPars mode, the command is rejected

with appropriate error message explaining the reason for the failure. The OVERRIDE option

overrides this normal behavior, and can result in a change in mode or can apply a destructive

operation to all vPars in an nPar.

The FORCE argument shuts down the specified partition ungracefully. If an OS is not running

on the partition, the FORCE argument is required to power off the partition.

IMPORTANT: When ALL option is used with OVERRIDE option, it is not supported. This

brings down all the partitions in the complex to the DOWN state.
