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.
Note the update process will check the disk space requirements. If the system doesn't meet the
requirements, the update will not proceed.

This higher limit is supported only with LVM volume group version 2.2 (and later).
Note that the Ignite-UX product from the respective release (or later versions) is required when boot
with a higher limit disk size is attempted. For example, the Ignite-UX product from March 2011
(or later version) is required when install or recovery is attempted on a 2 TB disk. The attempted
use of disks, physical volumes, or logical volumes with sizes higher than supported limits as HP-UX
boot devices will result in errors or failures.
