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 stable storage, you must either:
— go into standalone/nPars mode and use setboot or parmodify
— use parmodify for PA-RISC nPartitionable servers (parmodify is not supported from
within the vPars environment on Integrity servers)
— go to the BCH for PA-RISC or EFI Shell for Integrity systems
For more information on using the above firmware and HP-UX commands, see the
document HP System Partitions Guide, Managing Systems and Workgroups (11.11, 11.23)
or HP-UX Systems Administrator’s Guide (11.31), available at http://docs.hp.com.
• 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.
• For Integrity systems, including using the parmodify command in vPars mode and EFI
variables and booting, see also “EFI and Integrity Notes” on page 40.
For more information on how setboot works on a vPars server, see “Setboot and
System-wide Stable Storage” on page 164. For more information on the I/O attributes, see
vparresources (5) manpage.
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 158.
