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. 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. 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. 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. • Access level/Bay level: OA Administrator, OA Operator • Restriction: You must be connected to the monarch OA.

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.
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. 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.
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.
