Need to extend lvol3 to 6GB
Unable to do that ....can someone please suggest how can I do this?

lvextend: Not enough free physical extents available. ----> not possible, beacuse of lot so free space
Logical volume "/dev/vg00/lvol3" could not be extended.
Failure possibly caused by contiguous allocation policy.
Failure possibly caused by strict allocation policy

Can not change to non-contiguous allocation policy Logical Volume "/dev/vg00/lvol3" must be contiguous.

One way is/was to use ignite and make a a recovery tape or perhaps a net recovery, boot from that and make changes to the root logical volumes at that point.
If you have a spare disk, it can be accomplished with DRD. The steps are outlined in this document:

>>Need to extend lvol3 to 6GB
The first question is "WHY"? That seems awfully large for your '/' volume.
The "/" volume MUST be contiguously allocated. There is no way to get around that requirement.
The "easiest" way is to use Ignite/UX to do this, as mentioned above.
Another option, though it is a bit of work and you have to be REALLY careful, is to move the logical volumes that occurr after lvol3 on the disk so that you can then extend lvol3.

well, I HAVE to extend :-( as per the document.
All servers have been built as per that spec. Tis particular server, may be due to human error has been alloted less space
this is a vmhost on a bl860 blade
11.31 VSE OE
two local disks
H/W RAID mirrored..now just one disk can be seen - 550GB
Rest of the disks seen in this VM host are from SAN..used to create hpvm guests
free space in this local disk where OS is installed is over 300GB
move logical volumes after lvol3 to where? same disk? or some other disk?
will also be interested to hear more on ignite for this lvol3 extesion.

Can I please request ..
can I have a step by step procedure to take the sytem full back up ?
I have an ignite server with enough space....
and have the network connectivity too between this vm host and ignite
I have concluded that ignite is the way to go. DRD amy not work out as the disk size in this host is 550GB and I may not get that big LUN to clone.

The chapter # 15 of Ignite-UX Administration Guide at http://h20000.www2.hp.com/bizsupport/TechSupport/D
After having created a recovery archive, you may modify the root file system size at the time of recovery from the Ignite-UX user interface at the console.
