HP-UX Virtual Partitions Administrator Guide (includes A.05.08) (5900-1312, March 2011)

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 www.hp.com/go/hpux-core-docs.
• 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” (page 36).
For more information on how setboot works on a vPars server, see “Setboot and System-wide
Stable Storage ” (page 156). 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” (page 152).

Setting the Primary or Alternate Boot Paths
In the examples below, suppose you want the virtual partition winona2 to have its primary boot
disk at 0/8/0/0.5.0 and its alternate boot path at 0/8/0/0.2.0.
Using setboot
Because setboot affects only the virtual partition from which you execute the command, execute
these commands from winona2.
