Afaik you always have LVM under AIX. You can easy enlarge the FS/LV with it online. It will grab space from unused PP from your VG.
Example:
Code:
chfs -a size=+100M /home # adds 100 MB of space to the FS/LV
Mounting mountpoints into other mountpoints is not a good style. You can get trouble with mount orders etc. especially in cluster environments when you have loads of those.

Scenario1:
VG00 lvm,not mirrored,2 disk of 36GB vg size
VG00 size is under 30G.
Is possible to remove a disk of 36GB and replace "on fly"
with a disk of 300GB on VG00?

vxvmboot
vxvmboot(1M)vxvmboot(1M)NAME
vxvmboot - prepare Veritas Volume Manager volume as a root, boot, primary swap or dump volume
SYNOPSIS
/sbin/vxvmboot [-b|-d|-r|-s] [-v] -o offset -l length rawpath
/sbin/vxvmboot -v rawpath
/sbin/vxvmboot -c
DESCRIPTION
The vxvmboot command updates information in the LABEL file for the lif disk specified by the pathname of its character (raw) device node,
rawpath. The volume at the specified offset and length becomes the boot, root, primary swap or dump volume when the system is next booted.
This command is normally invoked by the vxbootsetup utility.
OPTIONS -b Specifies the volume type as a boot volume with name standvol.
-c Is used to update the /stand/rootconf file with the offset and length of the rootvol. The usage is slightly different when the -c
argument is used. The rawpath argument is not used with this invocation. Instead the path of the boot device is extracted from
the /stand/bootconf file. Also, the -o and -l arguments are not used to specify the offset and length. Instead, the offset and
length of the rootvol are obtained from the LIF LABEL file on the boot device.
The -c option would normally be used in the sbin/ioinitrc script to update the /stand/rootconf file, when the boot disk is VxVM
rootable.
-d Specifies the volume type as a dump volume with name dumpvol.
If a dumpvol volume exists on the specified disk, the extent information from this volume is used. If no such volume exists, the
extent information of the swap volume is used instead, and swapvol performs the dual role of swap device and dump device.
-l length Specifies the length of the volume in units of 1024-byte blocks.
-o offset Specifies the start of the volume as the number of 1024-byte blocks from the beginning of the disk.
-r Specifies the volume type as a root volume with name rootvol.
-s Specifies the volume type as a swap volume with name swapvol.
-v When used with one of the options -b, -d, -r or -s, displays the contents of the updated LABEL file. Otherwise, this option may
be used to display the contents of the LABEL file on the specified lif disk.
Note: The -b, -c, -d, -r and -s options are mutually exclusive. If more than one of these options is specified, the vxvmboot com-
mand exits without performing any operation.
ARGUMENTS
rawpath Specifies the pathname of the character (raw) device node for the lif disk.
