Increase LUN size in AIX with VIOS and HACMP

Hello!

I have this infraestructure:
- 1 POWER7 with single VIOS on Site A.
- 1 POWER6 with single VIOS on Site B.
- 1 LPAR called NodeA as primary node for PowerHA 6.1 on Site A.
- 1 LPAR called NodeB as secondary (cold) node for PowerHA 6.1 on SiteB.
- 1 Storage DS4700 on Site A.
- 1 Storage DS4700 on Site B.
- All VIOS versions are 2.2.0.13-FP24 SP-03.
- All AIX versions are 6.1.6.5.
- Power version is 6.1 SP3.
- Data VG is configured as LVM Cross Site, using one disk from each storage.
- Both disks are configured with reserve_policy=no_reserve in all VIOS an LPARs.
- queue_depth attribute is the same (10) in all VIOS and LPARs for this disks too.

My problem is that I can't increase the size of my data VG.

I increased the LUN size. Then I run cfgdev in both VIOS and cfgmgr in both LPARs. Also chvg -g datavg returns: "0516-1382 chvg: Volume group is not changed. None of the disks in the volume group have grown in size."

I've tried several ways to do this without luck.

Any suggestions?

Thanks!

OPTIONS

       The complete set of command-line options for octave is available by running the following command from the shell.

	   octave --help

DOCUMENTATION

       The primary documentation for Octave is written using Texinfo, the GNU documentation system, which allows the same source files to be  used
       to produce on-line and printed versions of the manual.

       You can read the on-line copy of the Octave documentation by issuing the following command from within octave.

	   octave:1> doc

FILES

       Upon startup Octave looks for four initialization files.  Each file may contain any number of valid Octave commands.

       octave-home/share/octave/site/m/startup/octaverc
	      Site-wide  initialization file which changes options for all users.  octave-home is the directory where Octave was installed such as
	      /usr/local.
