Switching Modes between vPars and nPars on Integrity Systems

Chapter 214

Switching Modes between vPars and nPars on Integrity

Systems

This section regarding modes and the new vPars commands for use on Integrity systems is

included in Chapter 5 of the Installing and Managing HP-UX Virtual Partitions document but

is duplicated here so that users are aware of this for vPars A.04.01 when using Integrity

systems. Please see Chapter 2 for further information on using vPars A.04.xx on Integrity

systems, including other Integrity-only specifics.

Usage Scenarios

• If you are running HP-UX in nPars mode (standalone), use the following vPars command

to switch to vPars mode:

OS-Prompt> vparenv -m vPars /* sets the mode for the next nPartition reboot */

OS-Prompt> reboot /* to reboot the system into vPars mode */

• If you are at the Monitor prompt, use the following Monitor command to switch to nPars

mode:

MON> reboot nPars /* sets the mode and reboots the system */

• If you are at EFI shell prompt, use the following EFI utility to switch to either nPars or

vPars mode:

Shell:> fs

:> vparconfig reboot nPars|vPars

Since vparconfig is not a built-in EFI shell command, you must go to the disk to execute

vparconfig. For example, to switch to vPars mode:

Shell:> fs0: /* go to the EFI partition of the disk */

fs0:> vparconfig reboot vPars /* sets the mode and reboots the system */

Note: vparconfig is an EFI utility which gets installed in the EFI partition during the

installation of the vPars product.

• If you are at EFI shell prompt in vPars mode and you do not have vPars installed on any

of your disks, you can use the built-in EFI command parconfig to switch to nPars mode:

Shell:> parconfig nPars

Shell:> parconfig reset
