HP Superdome 2 Partitioning Administrator Guide (5900-1801, August 2011)

Setting the mode using the OA CLI

• parmodify -p <npar_name> [-N] next_boot_mode

where:

next_boot_mode has the value of either vPars or nPars

Specifies whether the nPartition has to be booted as a single partition (nPars mode) capable

of running only a single operating system (OS) instance or as one or more virtual partitions

(vPars mode) as defined in the virtual partition database in the partition specification, each

capable of running its own OS instance.

Booting from the CLI

To set the vPars environment, you must set the nPartition into vPars mode so that the next

nPartition boot allows you to boot into vPars mode. To set the nPartition mode:

1. Set the nPartition in vPar mode.

# parmodify –p <npar_name> -N vpars

2. Do one of the following:

a. poweron partition {nPartition identifier}[:{vPar identifier}]

(Not specifying a vPar will result in all of the vPars in the nPartition to be booted.)

b. Use the pe command to prompt you for the partition to activate:

Example 4 Booting a vPar

This command controls power enable to a partition.
