Some doubts about resizing fs's in HP-UX

Hello,

I'm new to HP-UX and I'm not sure about some concepts related to resizing fs's under this OS.

First of all I'm only asking about resizing ONLINE, it means, without having to umount the fs nor rebooting, etc.

Q1. I've read that in order to resize a fs online there are 2 requirements:
1.1 the fs type must be vxfs <- Is that correct or under hp-ux there are more fs types that can be resized online?
1.2 JFSOnline is needed <- What's better to know if I have this feature: /usr/sbin/vxlicrep and see if HP_OnlineJFS = Enabled OR swlist | grep -i onlinejfs ? Is it possible to have the license but not the sw? and viceversa?

Q2. Then, there are 2 types (or more?) of underlying volume managers: LVM and VxVM.
2.2 How do I know if the fs's underlying VM is one or the other?
2.3 Case LVM and jfsonline -> I can resize fs online using lvextend + fsadm. Ok but lvextend and fsadm interpret sizes in powers of 2 or 10?
2.4 Lvextend -L XXX ... <- XXX is the new total size you want to achieve, not the size you want to add to the filesystem?
2.4 Case VxVM and jfsonline -> I can resize fs online using vxresize without having to worry about the underlying lvol?
2.5 if VM is VxVM can I use lvextend + fsadm and if i have LVM can i use vxresize?

Thank you!

Is there a way to take space from the /opt slice (/dev/dsk/c1t0d0s5) and then put it in the /var (/dev/dsk/c1t0d0s1)? In theory, I should be able to ufsdump /opt and /var to another drive. Use disk label to resize those two slices (ex. take 10G from opt and add to /var) and then newfs and dump back...
