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!
