HP-UX Virtual Partitions Release Notes (A.04.01)

vPars Release Notes

Switching Modes between vPars and nPars on Integrity Systems

Chapter 1 9

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.04.01 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
