We have HPUX 11.11 and have room on the disks of our EVA 4400 to extend some LVs. I have OnlineJFS and would like to do this through SAM. Here are my questions:
- Can I safely do this through SAM?
- Will SAM do the lvextend as well as the fsadm portions of the tasks?
- Will unmounting or re-booting be required?
Thanks in advance.

Re: Extending LV through SAM
Kind of thought so, just wondered if there were any gotchas.

Re: Extending LV through SAM
don't count on SAM, for anything, always seems to have something broken...
lvextend -L XXXX /dev/vgname/lvolname
fsadm -b XXXXm /mountpoint
(XXXX is a number in MB)
if you need to add another lun to the vg then add do that first then extend the lvol.
pvcreate /dev/rdsk/cxtxdx
vgextend /dev/vganem /dev/dsk/cxtdxdx

Re: Extending LV through SAM
In fact Tim, you caused me to re-think that perhaps just to be on the safe side, I may want to do it manually.
Thanks

Re: Extending LV through SAM
You need to create new vdisks and add them to your existing VGs.
This is an easy task and even SAM can do it.
But it's no problem to do it manually - just pvcreate the new LUN, vgextend, lvextend and finally extend the file system.
Check if you use striping before you begin, maybe you need to add more than 1 LUN.
Hope this helps!
Regards
Torsten.
