You didn't state your AIX version, but the extract from the AIX 5.2
Redbook SG245765 section 4.2.11 goes like this:
========
For example, to increase the size of a LUN in a FAStT 500 storage
subsystemand make AIX aware of this change, the following steps need to
be performed:
1. Change the size of the LUN in the FAStT 500 storage subsystem.
2. Unmount all file systems in the affected volume group for every file
systemusing the following command:
umount /filesystem
3. Vary off the volume group, using the following command:
varyoffvg vgname
4. Vary on the volume group, using the following command:
varyonvg vgname
5. Mount all the file systems unmounted in step 2, using the following
command:
mount /filesystem
6. Add the new PPs to the volume group using the following command:
chvg -g vgname
The growing of disks in the rootvg and in activated concurrent VGs is
not supported. The change of the chvg command is reflected in Web-based
System Manager.
========
HTH,
Andy.
