Boot||Shut: Using Primary and Alternate Boot Paths
You can set the primary and alternate boot paths of a virtual partition by using the HP-UX setboot
command or the vPars command vparmodify and the BOOT and ALTBOOT attributes.
NOTE Like many other HP-UX applications, MirrorDisk/UX software is supported. However, vPars
does not have a knowledge of the mirror configuration. If your boot disk is mirrored, you may
want to explicitly configure the mirror disk as the alternate boot path. Also, on Integrity
systems, after creating a mirrored boot disk, you will have to do either a 'setboot -[p|a|t]
<path> or vparefiutil -u to be able to boot from the mirror later.
To modify the paths in stable storage, you must go to the BCH for PA-RISC or EFI Shell for
Integrity systems.
For Integrity systems, including using the parmodify command in vPars mode and EFI
variables and booting, see also “EFI and Integrity Notes” on page 35.
For more information on how setboot works on a vPars server, see “Boot||Shut: Setboot and
System-wide Stable Storage” on page 135. For more information on the IO attributes, see
vparresources (5) manpage.
The boot path setting for HAA (High-Availability Alternate) is not supported for vPars
instances. For more information on HAA, see the HP System Partitions Guide.
Autoboot and Autosearch Attributes
Beginning with vPars A.03.02, there is a new attribute called autosearch, in addition to the existing autoboot
attribute. The autosearch attribute has the value of either search or nosearch (the default is nosearch). See
the table below for the results of the combination of possible values. For further information on the attributes,
see the vparcreate (1M) or vparmodify (1M) manpages. For information on setting these attributes, see
“Managing: Modifying Attributes of a Virtual Partition” on page 126.

nPartitionable servers: do not attempt to boot the primary path; attempt to
boot the alternate path. These actions match the nPartitionable firmware
actions. For more information, see the setboot (1M) manpage.
