HP-UX 11i Version 1 Installation and Update Guide, December 2003

Preparing To Move To HP-UX 11i v1
Preparing your system for HP-UX 11i v1
Chapter 4 97
Preparation Tasks Before you update your system, we recommend that you take the
following actions:
Record Software Versions
To identify what software still needs updating after the OS update, print
a swlist listing of all products and bundles prior to the update. For
example, enter:
/usr/sbin/swlist | lp
Then compare it with a similar swlist executed after the update.
Update maxdsiz Configurable Kernel Parameter
If you are updating from either HP-UX 10.20 or HP-UX 11.0, you will
need to increase the maxdsiz configurable kernel parameter to at least
128MB prior to rebuilding the kernel. This will ensure that the kernel
will not run out of memory during mk_kernel after the update.
Rebuild Kernel
Your update could fail if the HP-UX kernel build fails in the starting
environment. To ensure that you have a reliable starting point, rebuild
the kernel before you update:
1. As root, run the mk_kernel (1) command.
2. Fix any problems listed in the mk_kernel output.
3. Reboot your system to ensure that your new kernel boots.
Clean Out Your Log Files
To make it easier to check for problems encountered during an update,
rename the log files before starting an update:
1. cd /var/adm/sw
2. As root, rename each log file. For example:
mv swagent.log swagent_old.log
