Also, can someone double check my procedure:
1) Grow LUN on EVA. Check
2) Expand physical volumes?
3) Expand volume group (vgextend vg04 /dev/rdsk/c8t0d3)
4) Expand LVMs (lvextend -l 7680 /dev/vg01/lvm1)
5) Grow the VxFS file system (fsadm -F vxfs -b 614400 /z01)
Thanks,
Geoff

Re: Growing a file system from an EVA
I believe HPUX didn't support if you grow the LUN size on EVA. What you should do:
1. Create a new LUN on EVA
2. Present the LUN to the server
3. pvcreate the disk and then vgextend the vg
4. extend the LV
5. extend the filesystem
regards,
Sandy

Re: Growing a file system from an EVA
1. Do you increase the existing lun or Create a new LUN? if you extend the existing, it doesn't possible. If you create a new disk please note: the new disk can't bigger than existing disk. you will have problem about that.
2. please check max pe per pv.

Re: Growing a file system from an EVA
Since years this question was not important, because non of the HP arrays were able to increase a LUN size. For this reason the only way out was delete the LUN and create a new and bigger one. Of course this was followed by creating new devices with "pvcreate" etc. Another possibility was and is to create a new LUN and leave the old LUN in place and vgextend the VG with the new LUN.
Now with the EVA this is different.
I still guess you cannot increase the size of a physical device (from the LVM point of view), but I was wondering about the "pvcreate" manpage:
"-x extensibility Set the allocation permission to add physical extents to the physical volume pv_path. extensibility can have the following values:
y Allow allocation of additional physical extents on the physical volume. This is the default."
No idea what the meaning is. Somebody?
Hope this helps!
Regards
Torsten.

SolutionOnly VMS, Windows and possibly Linux support LUN size expansion on the EVAs.

Re: Growing a file system from an EVA
This '-x' option of vgextend sounds very interesting. Does anyone know if HP-UX 11.31 supports extending a physical volume (ie allocating additional physical extents to a physical volume) in LVM? What about 11.23?
Strange that it would appear in an 11.23 man page, yet apparently not be supported on the platform?
Has anyone played around with the -x option?
This would certainly be a useful feature since adding disk space to a volume group can get messy over time when you keep adding small LUN's over time to accomodate the VG growth. Adding larger LUN's instead of smaller ones doesn't solve the problem either, it merely defers it. So it would certainly be handy to be able to extend PV's.
Thanks all.
