HP-UX 11.00 upgrade to 11iv1

[catastro]

Hi to all. I have to make a cold install in a server next week and about the tasks I have to do for doing it, I have some questions about some.
- First, how can I review the kernel parameters when the new system is up and change them for making them to be at a minimum for the system? And how can I list them in the old system for having a view of the of the parameters?
- Second, I know how to create a swap lvol, but how can I choose the priority 0 or 1?
- Third, I know how to make the mirror of different lvols with lvextend, but can I do the same with an entire vg with vgextend at once? I am looking to the man, but can not find it.
Thanks for your help.

Hi,

have a look into this file
/stand/system

You should use SAM to adjust the values on the new system.

The "lvextend" is the only command to set-up a mirror, vgextend doesn't work to mirror LVOLs.

The procedure is here:

Hi,
to set the priority
see "man 1M swapon"

Hello catastro.

For reviewing the kernel parameters you can run the sysdef command.

sysdef will show you every kernel tunable parameter

you car redirect the uotput of this command to a text file for example.

Hope this helps and buena suerte amigo :D
