HP-UX 11i v3 Installation and Update Guide, September 2012

Note the following:
• The table shows recommended minimums.
• Ignite-UX will enforce absolute minimums, but they are smaller than recommended sizes in
some cases.
• Ignite-UX will consider available root disk space and adjust sizes to be larger.
• The Ignite-UX UI File System tab can be used to set specific sizes.
CAUTION:
If the default size for the /stand partition is too small for your environment, do not use the
lvextend command to increase the size of the /stand partition; doing so might render your
system unbootable. Instead, use a Dynamic Root Disk (DRD) clone to create an inactive copy of
the system on which /stand can be extended, or use Ignite-UX recovery to create a recovery
image and resize the /stand partition.
To use a DRD clone to extend /stand on an LVM-managed system, see the white paper “Dynamic
Root Disk: Quick Start and Best Practices” (http://www.hp.com/go/drd-docs). Further information
on DRD is available at the DRD website: http://www.hp.com/go/drd. See also “Reducing downtime
using Dynamic Root Disk” (page 29).
You can boot from an Ignite-UX recovery image and resize /stand as you recover the system.
For help creating a recovery image, see the Ignite-UX Administration Guide available at the Ignite-UX
website: http://www.hp.com/go/ignite-ux.

Depends on application and user requirements. It might
make sense to mount a separate file system at /home.

These are recommended minimums and are estimates only. Requirements for partitions/file systems, especially /var,
might vary depending on the size of your disk, your type of server, and your Operating Environment.

In other words, you might want to put /home on a separate disk and separate volume group. This makes future recovery
and upgrade operations easier. By default, /home is created as a separate file system; however, it is part of the root
volume group.
Disk space requirements for an update
To ensure a successful update to HP-UX 11i v3, make sure that you have at least as much disk
space allocated to the partition/file system listed in Table 3 (page 12) and that each partition/file
system (most importantly, /usr, /opt, and /var) has at least 10-20 percent free space to allow for
any growth.
