HP-UX 11i v3 Installation and Update Guide, March 2014

The list below provides additional hints and information to help you determine your disk needs for
HP-UX 11i v3. If you need more disk space, be sure to order the equipment and plan on installing
it after backing up your current system.
• Record the hardware path to the DVD drive.
• Develop a clear configuration plan, including:
file system sizes◦
◦ Swap space size
◦ Dump device
◦ Disk and file system parameters
◦ Mirroring information
• If installing application programs other than those supplied within an HP-UX 11i v3 Operating
Environment (OE), consider the vendor’s size recommendations.
• When planning disk space, see the HP-UX System Administrator’s Guide. Composed of five
volumes, this guide is available on the Instant Information DVD and at http://www.hp.com/
go/hpux-core-docs-11iv3.
Disk space requirements for a cold-install
The disk space requirements listed in Table 3 (page 13) are estimates only. Requirements might
vary depending on the size of your disk, your type of server, and your Operating Environment.
HP strongly advises you install all OS content on one disk, except for mirrors. That disk must be at
least 30 GB.
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 30).
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.
