HP-UX Update Requirements

Update and Upgrade You can use the SD-UX tools to update your OS to a later version of
Paths
HP-UX, from 10.01, 10.10, or 10.20. For upgrades to 10.x from 9.0x, see
the manual Upgrading from HP-UX 9.x to 10.01. You can also use SD-UX
to install or update applications.
Memory and Disk • HP-UX (after 10.20), including NFS, LAN/9000, and CDE, requires

the space needed to accommodate the new OS as well as your data
files and all needed backups on disk. HP-UX (after 10.20) requires
271 MB, including NFS, LAN/9000, CDE, and the X Window System.
This means you should plan on a minimum of one GB for a general
workstation. Disk usage numbers will vary by a factor of 20%,
depending on the SD-UX installation.
In general, the Disk Space Analysis phase of swinstall will warn
you if disk space is insufficient. However, Disk Space Analysis does
not currently check /var/adm/sw, where the database is kept, for
temporary space usage.
If you are running your system as LVM and /var comprises a single
volume, be sure you have configured adequate space in the /var
volume to accommodate the update files. Update requires a minimum
amount of free disk space of at least 20 MB to allow for the generation
of the installed software database, among other things. Note that
other LVM volume sizes may also need to be increased to allow
updating. You may need to observe the result of the disk space
analysis step and adjust the volume sizes as needed.
1. Determine your free disk space in /var by running bdf /var and
bdf /var/tmp. The default temporary directory is /var/tmp.
2. Delete any files in this volume that you don't need.
3. If necessary, set the environment variable TMPDIR to point to a
directory that has sufficient space. For example (for a directory
dir):
TMPDIR=/dir
