HP-UX 11i v3 Installation and Update Guide, February 2007 (Initial Release)

System Requirements for Cold-Installing and Updating
System Requirements
Chapter 230
NOTE During installation, Ignite-UX (on the File System tab) shows a higher
percentage of disk space used than the information in Table 2-1 shows.
The minimums enforced by Ignite-UX ensure that the cold install
completes successfully without filling a file system. This difference exists
on all versions of Ignite-UX.
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 file partitions listed in Table 2-1 on
page 29, and that each partition (most importantly, /usr,/opt, and /var)
has at least 10-20 percent free space to allow for any growth.
Disk Space Allocation for File Partitions
Depending on your system’s purpose, you may need to determine how
much disk space you will need for each file partition before you
cold-install or update to HP-UX 11i v3. For example, if you plan to install
applications from other vendors, you may need to modify the size of the
/opt partition to accommodate their size. Depending on how much disk
space is available, you can change the partition size to meet your needs.
For information about modifying your file system, see the HP-UX System
Administrator’s Guide at the HP Technical Documentation Web site:
http://docs.hp.com
NOTE 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 may render your system unbootable.
Instead, use either System Management Homepage to extend the
/stand partition or Ignite-UX recovery to create a recovery image and
resize the /stand partition. You can boot from the recovery image and
resize /stand as you recover the system. For help using System
Management Homepage, refer to the smh (1M) manpages or the HP SMH
Online Help included with the product. For help creating a recovery
image, refer to the Ignite-UX Administration Guide available on the HP
Technical Documentation Web site: http://docs.hp.com
