twice the swap space (1024) that I have (512).
I tried SAM to increase the space but the message :
can not umount the system to increase space because devices is busy:
or not enough "extendts" to increase the space
Solved! Go to Solution.

Re: HPUX 10.20
There are previous posts that detail the steps involved in creating the swap. Can do a search withing the forums using the keyword of "swap"

Solutionswap need to be contigous. You should check: if you have space in vg00, if you have unallocated physical extends just next after swap. (ex. swap's last extend is 0070, you have to have 0071 and up unallocated...; run lvdispay -v /dev/vg00/lvol02 (what ever is swap lv called); lvdisplay -v /dev/vg00/lvol3). If you have the required contiguous space, you have to go in single user mode and from command line use lvextend command. (if you choose to go with this, and you need help come back with details about output from lvdispay).
But, you can try to create a secondary swap device, creating a new lvol and allocate it as swap (that is possible using either sam or command line).
You can use a file system as swap as well (I would not do it except emergency or/and limited time).

A good description of using sam to add swap is in

To answer to your secondary question, well, when a fs is busy you can not mount it.
When a fs is busy? When a running process is touching it. (the application that resides in the fs is running, or a file from that fs is in use (read, write). You can get "fs busy" even if a user is sitting (cd in) one directory from that fs.
So, using fuser command you can identify the processes that are touching that fs. It is your choice to stop the application or kill the process. fuser has a option to kill directly the processes. After that fs is not in use, you can umount it....
