swap help

[lawrenzo_1]

Hello,

I am getting quite confused whilst following a company procedure to install hpux to an n400 server. Can some explain the following;

I have configured a seperate swap device in the basic tab, then two dump devices and also /var/adm/crash filesystem under the filesystem tab in the cfg menu,

i know the purpose of swap but don't understand this config - can someone help?

THANX

The separate dump space is used if/when your system crashes. During the crash the contents of RAM get written to the dump space.

Then when the machine is booting back up, the dump space is read and the crash dump is compressed and written to /var/adm/crash.

That is actually a very good way to set it up. The one thing I would do differently is to not have the dump space on the OS disk/disks. Dump space can be any kind of cheap disk. It is not used often and there is no reason, really to use the OS disk or an high end disk array for it.
