install question

[navin]

Hello,
Actually i wanted to be careful for any future hp installs . As last time the remaining space of the root disk was added to / .And i was not able to inclease any other file system as there is no space available.So please let me know how i can make sure of having space available for any future increase on the other file systems(except / and stand).
Much appreciated

Hi:

1. Plan ahead. Follow the guidelines for filesystem sizes given in the release notes for the operating system level. Be generous with space for '/var', '/opt' and '/usr' to allow log space, optional HP-UX products and open-source (including from the HP-UX porting center).

2. Put additional secondary swap on a non-vg00 volume, leaving your primary device swap relatively small. Primary device swap can be much less than total physical memory with secondary swap accomodating your needs.

Regards!

In general, the amount of disk spaced needed by HP-UX is ~11 GB, plus or minus. Less is needed for the older versions like 10.20. More is needed for the newer versions like 11.3#.

In today's world of HUGE disks, how did you run out of 11 GB? Even a small pair of old 36 GB disks is much more than enough.

Are you use the o/s disk for data? Bad, bad idea. If you're doing this and storing application or database data on your O/S disks then not only will your performance be awful but you open yourself up to additional risk.

You should not be doing this.
