Issue with increasing size of SAN disks on AIX

HI, I have had an issue last night while trying to extend a filesystsem . chvg -g <vg> command cameback with an error

0516-1790 chvg: Failed bootinfo -s hdisk9. 
        Ensure the physical volume is available and try again. 
0516-732 chvg: Unable to change volume group u01vg.

the VG has 1 filesystem

lslv -l <LV> command
PV                COPIES        IN BAND       DISTRIBUTION 
hdisk9            2659:000:000  20%           533:533:532:532:529 
hdisk10           2658:000:000  20%           533:533:532:532:528 
hdisk36           2658:000:000  20%           533:533:532:532:528 
hdisk37           2658:000:000  20%           533:533:532:532:528

I have tried umounting the filesystem and varying off and on the VG but same issue.

its a production DB2 database so i really cant easily get outages like this. Any ideas anyone.

Off the top of my head:

Is this VG part of a HACMP resource group? If yes, it most certainly is varied on in EC mode and "chvg -g" will not work then.

Is hdisk9 available? "bootinfo" will fail if the disk is only in defined state.

I hope this helps.
