About Online Dynamic Lun Expansion in HP-UX 11.23

[compiler]

Hi, I would like to know if it's possible to do ONLINE DLE under HP-UX 11.23.

DLE's pdf documentation says that "the vgmodify command line interface is available under v2 with PHCO_35524 installed".

Also, this thread says that "some of the dynamic LUN expansion features of LVM in 11iv3 (through the vgmodify command) have now been back-ported to 11iv2.":

But I have installed 2 patches that supersede PHCO_35524 and PHKL_36244 (PHKL_36745 y PHCO_36744 installed in my system) and my vgmodify doesn't show -a and -E flags:

# vgmodify
Usage: vgmodify
[-e MaxPhysicalExtents]
[-p MaxPhysicalVolumes]
[-l MaxLogicalVolumes]
[-v]
[-n]
[-r]
[-B bootable]
VolumeGroupName {[pv_path] [pv_path] (...)

Is ONLINE DLE ***only*** available under v3?

Thanks.

I've read it about 6-7 times before posting :-)

The above document makes the following reference to v2:

"""The vgmodify command interface is available on HP-UX 11i v2 with the PHCO_35524 patch and 11i v3."""

But I have PATCH PHCO_36744 (that it supossed to supersede PHCO_35524 at least according to HP's website) and my vgmodify has not -a or -E options.

I think you answreed your own question really didn't you?

Anyway just for confirmation - this is from the man page for vgmodify on 11iv2:

The volume group can be active when reporting the configuration (-r)
or displaying a table of available settings (-t). The volume group
must be de-activated before vgmodify can perform any configuration
changes (see vgchange(1M)).


You won't see this on the man page for 11iv3

Thanks a lot for your answers. I don't really think (please, no offense) it's clear enough in the documentation. I did really thought that "DLE backported to v2" meant "all DLE options", not just offline resizing.

Anyway, another time thanks a lot for your answers :-)

I'm new to HP-UX but I'm starting to feel more comfortable thanks to all you :-)

HP-UX v2 doesn't support ONLINE Dynamic Lun Expansion.
