VxVM disk/lun grow

hi,
i have a volume on a LUN of an EMC-storage and i need to increase the
size.
i could increase the size of the LUN on the EMC, i could increase the
size of the disk for solaris, but how can i tell the veritas volume
manager that the disk is larger now?

what i've done:

1. LUN on EMC
2. in the format menue i' ve chosen the type to autoconfigure, i can see
the bigger disk in solaris, then in the partitions menu i've created the
VTOC like before, only one slice on 7 (and 2 for backup, like before) for
the whole space.
but VxVM still means
# vxassist -g datadg maxsize
VxVM vxassist ERROR V-5-1-752 No volume can be created within the given
constraints
# vxassist -g datadg maxgrow datavol
VxVM vxassist ERROR V-5-1-1178 Volume datavol cannot be extend within the
given constraints

so i tried "vxdctl enable", but still the same... but i can still work
with the volume.. it must be written in the privatregion somewhere...
any ideas?

V440, solaris9 (09/05), VxVM 4.1, VxFS 4.1

thanks in advance,

vgrestore

vgrestore(1M)															     vgrestore(1M)

NAME

       vgrestore - restore a VxVM disk group back to an LVM volume group

SYNOPSIS

       /etc/vx/bin/vgrestore vg_name

DESCRIPTION

       The  vgrestore command restores a Logical Volume Manager (LVM) volume group that was previously converted to a VxVM disk group by the vxvm-
       convert utility.

ARGUMENTS

       vg_name
	    Specifies the name of a volume group that was converted to a VxVM disk group by the vxvmconvert utility.

EXIT CODES

       vgrestore exits with one of the following values:

	0   Successful completion.

       >0   Failure; an error occurred.

WARNINGS

       vgrestore functions only on VxVM disk groups that were converted from LVM volume groups by the vxvmconvert command.

       It is a good idea to back up user data before running vgrestore, and restore it after  the  vgrestore  completes,  as  vgrestore  can  only
       restore	a logical volume back to the state it was in before conversion to VxVM.  If data changed on the volume while it was a VxVM volume,
       the changes won't be reflected on the volume after being restored to LVM.

       As part of the original conversion process, applications that once referenced the now-converted LVM volume's path names may have changed to
       reference  VxVM	volume special device file names.  Alternatively, special device file path names originally representing the now-converted
       LVM volumes may have changed to symbolic links pointing to the VxVM volume path names.  Be sure to undo these actions when  restoring  back
       to LVM.

       Do  not	use vgrestore unless you are certain that you want to restore LVM volume groups.  After vgrestore this is run, the VxVM disks will
       no longer exist.

EXAMPLES

       To restore the LVM volume group vg03 that was converted by vxvmconvert to the VxVM disk group dg03, enter:

	      vgcfgrestore vg03
