Re: Transfer some frre memory
If vg01 consist of multiple PVs, you can vgreduce(1M)a PV from vg01 and vgextend(1M) it into vg00. But don't forget to make backup of /hpws3_dsk1, because data on it probably will be corrupted. The safest way to reconfigure disk space is to make ignite tape and assign VGs parameters in interactive restore.

man vgreduce(1m), vgextend(1m), lvreduce(1m), lvextend(1m), extendfs(1m) and fsadm(1m).

Re: Transfer some frre memory
There are some basic rules of logical volume manager. First rule is that one disk can not be part of more then one Volume group because of this you can not share PEs across volume groups.
If bot logical volumes are in same volume group then you can reduce one volume and assign these PE's to anothe voulmes.
For this you have to reduce first file system by lvreduce and extend other one using lvextend.
this is not as simple as i said above.
when you reduce your volume you may loose your data in that volume. you have to have Online JFS product for this.

Re: Transfer some frre memory
You do have a 2.5GB / filesystem. That is rather big.
In HPUX you can not resize / online. This has to be done with an "ignite tape" and ignite is the recommended method. You might want to look at finding space in the filesystem. There might be some clutter.
Is this your full bdf listing ?
