Important Operations for VPARs booting in vPars and nPars environments (HP-UX)

Note: These apply to VPARs versions 4.x/5.x . For the latest in case of any differences refer to the latest documents on the VPARs

Commands for the VPARs:

Switching between the vPars and nPars mode: INTEGRITY ONLY:

1) HP-UX > vparenv :

If the system is booted in the NPARs MODE

#vparenv –m vPars

#shutdown –ry 00

In the EFI SHELL, SHELL> fs0:

Fso:> boot /stand/vpmon vparload –all

If the system is having all the VPARs up and running and we need to reboot the same in the NPAR mode.

#vparenv –m nPars

Shutdown all the VPARs one by one.

#shutdown –hy 00

On the Monitor prompt VPMON

MON> reboot

EFI SHELL> fs0:

Fs0:>boot /stand/vmunix

VPMON

MON>reboot nPars

MON>reboot vPars

EFI

Fso:>vparconfig reboot vPars

Fs0:>vparconfig reboot nPars

Vparconfig is not a Built-in EFI Shell command. This is installed in the EFI Shell of the disk at the time of installing the VPARs Bundle on to the system. This has to be executed from within the EFI shell of the disk.

Vparconfig is not a Built-in EFI Shell command. This is installed in the EFI Shell of the disk at the time of installing the VPARs Bundle on to the system. This has to be executed from within the EFI shell of the disk.

parconfig:

EFI Shell>

SHELL> fs0:

Fs0:>parconfig nPars –n

Fs0:>parconfig reset

It is recommended to perform the mode changing and the reboot using the vparconfig command instead of the parconfig whenever possible.

However in the cases when the VPARs product is not installed or using the other disks for the booting purposes we can use this as this command is present on an NPAR system Disk EFI even if the VPARs Bundle is not installed.

Parconfig can not be used to set the mode of the system to the VPARs mode.

NOTE:

1) If vparconfig reboot vPars is used and before that the mode is not set to vpars using the UNIX command vparenv –m vPars it is not possible to boot the VPARs.

2) It is always recommended to set the modes using the vparenv rather than vparconfig of the Disk EFI.

3) Setting the mode to vPars for the first time we must use the command as vparenv.

4) If the desired mode is not set, it will not be possible to boot in that mode.

vparefiutil:

The vparefiutil is a UNIX command that is used to update the EFI mappings in the VPDB /stand/vpdb or in the alternate VPAR Database.

The setboot or the vparmodify command only updates the entry in the VPDB, but does not update the EFI boot paths mappings of the VPDB.

During the boot of a VPAR, the VPMON reads the VPDB and transparently provides the boot path EFI settings so that the VPAR can boot.

Whenever the boot path of a disk changes or an additional boot disk is added including the addition of a boot mirror disk, the EFI mappings within the VPDB has to be updated otherwise it shall not be possible to boot that VPAR.

So vparefiutil has to be executed in the form on all the VPARs as

#vparefiutil –u –D /stand/vpdb
