lvextend: Not enough free physical extents available. PVG-Strict or Distributed allocation policies.

[Gustavo Venturini deLim]

Hello Everyone.
I'm using a HP-UX 11.00 and a VA7100.
Need to extend and lvol and the lvextend comes back and tells me:

§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§
lvextend -L 302976 /dev/vg16/lvvg16
lvextend: Not enough free physical extents available.
Logical volume "/dev/vg16/lvvg16" could not be extended.
Failure possibly caused by PVG-Strict or Distributed allocation policies.
§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§§

I've add 2 disks devices (/dev/dsk/c30t1d0 and /dev/dsk/c40t0d7), both whit 8Gb and now I want to use this free space.

I'm in doubt about the "Alternate Link" showed on the vgdisplay... Don't know if maybe that's the problem...

Just warning that the thread have a attachment with the outputs...

lvdisplay /dev/vg16/lvvg16

Does it say strict under policy?/ If yes, you will have to change it and then proceed. Also is enough fee extends available?? vgdisplay /dev/vgxx

RAC, the outputs are in the previous message.

Hi

Just want to make sure the 2 disks where added to the same vg and also

vgdisplay -v /dev/vg16 to see if you have enough free PE.

Your answer lies in your lvdisplay output. Your policy is PVG-strict/distributed.

You need to add same no. of disks as they are in that PVG group.

Hello,

Im not sure, but if you use policy pvg-strict you should add the new volumes to a (new) pvg. Because of policy distributed i suggest a second pvg.
Try
vgextend -g pvg16-2 /dev/vg16 /dev/dsk/c30t1d0 /dev/dsk/c40t0d7
or edit /etc/lvmpvg.
Then use
lvextend -L 302976 /dev/vg16/lvvg16 pvg16-2

Alternative Link means both of your disk controllers (c30, c40) see the same (physical) disk(s).
You should probably do
vgextend /dev/vg16 /dev/dsk/c40t1d0 /dev/dsk/c30t0d7
too.

Best regards,
Thomas
