Updating HP-UX

HP-UX 10.20 System Requirements

For general system requirements for updating, please see “HP-UX 10.20

System Requirements” in Chapter 1, “Before You Install.”

Update and Upgrade

Paths

You can use the SD-UX tools to update your OS to HP-UX 10.20 from

either 10.10 or 10.01. For upgrades 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

Space Requirements

• HP-UX 10.20, including NFS and LAN/9000, requires 16 MB of RAM.

• Before you begin the update, you should be sure your target disk has

the space needed to accommodate the new OS as well as your data

ﬁles and all needed backups on disk. HP-UX 10.20 requires 271 MB,

including NFS, LAN software and X Windows. This means you should

plan on a minimum of 525 MB for a standalone workstation. Disk

usage numbers will vary with the SD-UX installation by a factor of

20%.

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.

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

After setting this variable, export it, and kill and restart the

swagentd process.
