how we can increase the size of swap space from 1500 to 2500 Mb?

Hi,

Swap space needs to be contiguous. The extension is an issue because most likely the space (on disk) "after" the swap space is already allocated somewhere else.

I would suggest making another (new) lvol for more swap. Create the new lvol (using lvcreate -r n -C y) and then use the swapon command.

Don't forget to add the new volume in fstab accordingly.

Cheers

Elia,
swap needs to be contiguous, but your vg00 does not have enough contiguous space to expand.
Secondary swap file can be created on a different vg.

thanks for the reply all.
it works fine.

[Steve Lewis]

I take it that you have noticed disk c1t2d0 is STALE / UNAVAILABLE in vg00, so your root disk mirror needs replacing?

[George_206]

Steve,

Can you explain a little bit what this issue is about ?

Thank you.

George.

This shows that the disk is dead.

There are two thing you should do:

1) call HP to replace the disk
2) Do some HPUX courses.

Thanks everyone.
We have called HP suppor tto replace the disk.
Thanks.
