Updating HP-UX
HP-UX 10.20 System Requirements
/usr/sbin/swagentd -r
4. Ensure that your system has at least 30 MB of swap enabled before
starting the update process. You can use swapinfo -mt and check
the total free MB of swap space. Or you can use SAM to see how
much swap you currently have. If you do not have enough swap,
you can enable filesystem swap for the duration of the update
(until system reboot) by using the following command:
/usr/sbin/swapon /var/tmp
The directory /var/tmp can be used if there is sufficient free
space. If /var/tmp is full, then specify a different volume that has
enough free space to satisfy the swap space requirement.
Alternatively, you can shut down unneeded programs to make
more memory and swap space available. This also improves
performance, especially in 16 MB systems.
• Before updating, you may wish to use /usr/sbin/swremove to
remove unneeded filesets from your system. You can use the
freedisk tool on a system which has been active for a time to detect
unused filesets.
