This means that an OS in a virtual partition can be booted from the UEFI, just like an nPartition. Standard UEFI/loader/OS mechanisms can be used to set boot disks, specify kernel paths and kernel boot options for a vPar. NOTE: Consequently, there is no support for specifying boot disk, kernel boot path or kernel boot options in the vPar commands. OS commands like setboot now directly operate on the stable storage of the virtual partition instead of updating the vpdb (which used to be the case on earlier platforms). For example, if you are logged into virtual partition Oslo2 and execute the command: Oslo2# Oslo2# setboot -b on this would set the "autoboot" attribute to "ON" in the stable storage of virtual partition Oslo2. On Superdome 2 platforms, when running in a vPar OS, the following options of the setboot command may be used to alter boot settings on a virtual partition: -p : To set the primary boot path -a : To set the alternate boot path -b : sets the autoboot attribute for the vPar -h : sets the HA-alternate path for the vPar Alternatively, the boot options can also be managed from the UEFI Shell.

After the virtual partition is in the down state, remove the virtual partition vPar0001:
vparremove -N nPar0001 -p vPar0001 -f
CAUTION:
Involuntary use of this command leads to unforeseen consequences. Therefore, you
must confirm the operation with the
-f
(force) option.
Boot options management for partitions
On HP Superdome 2 servers, each virtual partition has its own instance of UEFI. This means that
an OS in a virtual partition can be booted from the UEFI, just like an nPartition. Standard
UEFI/loader/OS mechanisms can be used to set boot disks, specify kernel paths and kernel boot
options for a vPar.
NOTE:
Consequently, there is no support for specifying boot disk, kernel boot path or kernel
boot options in the vPar commands. OS commands like setboot now directly operate on the stable
storage of the virtual partition instead of updating the vpdb (which used to be the case on earlier
platforms).
For example, if you are logged into virtual partition
Oslo2
and execute the command:
Oslo2#
Oslo2# setboot -b on
this would set the "autoboot" attribute to "ON" in the stable storage of virtual partition Oslo2.
On Superdome 2 platforms, when running in a vPar OS, the following options of the setboot
command may be used to alter boot settings on a virtual partition:
-p : To set the primary boot path
-a : To set the alternate boot path
-b : sets the autoboot attribute for the vPar
-h : sets the HA-alternate path for the vPar
Alternatively, the boot options can also be managed from the UEFI Shell. For details on managing
boot options at the UEFI Shell, see the HP-UX Installation guide at:
