You will need to read more about LVM. Physical volumes running out of space is not problem always. It does not affect user diectly. The user will be affected when his fileystem [ the one which is made using a logical volume ] fills up. You find it out by a df command.

So , AIX storage in simple words go as follows, One or more Physical Volumes [PV , a physical disk or a LUN from SAN] make a Volume Group [ VG ]. A VG can then be sliced to Logical volumes [ LV ] of whatever size the VG can accomodate. LV's are formated [then called a filesystem] and mounted on a mount point so the user can access.

vxdestroy_lvmroot

vxdestroy_lvmroot(1M)													     vxdestroy_lvmroot(1M)

NAME

       vxdestroy_lvmroot - remove LVM root disk and associated LVM volume group

SYNOPSIS

       vxdestroy_lvmroot [-v] [-b] lvm_root_disk

DESCRIPTION

       The  vxdestroy_lvmroot  command	tears  down  and removes the LVM volume group associated with the specified physical disk. This is done by
       removing the volumes in the volume group and then removing the volume group.

OPTIONS

       -b	 Invokes the setboot command to change the primary boot disk to the VxVM root disk from which the system was booted (if  the  pri-
		 mary  boot  disk is not already set to this disk).  The alternate boot device remains unchanged.  If the -v option is also speci-
		 fied, the settings of the primary and alternate boot devices are displayed.

       -v	 Outputs verbose messages including a timestamp that indicates major operations being performed.

ARGUMENTS

       lvm_root_disk
	    Specifies the device name of the LVM root disk that is to be destroyed, along with its entire volume group.

EXAMPLES

       This example shows the vxdestroy_lvmroot command invoked in its simpliest form:

       /etc/vx/bin/vxdestroy_lvmroot c5t1d0

       # /etc/vx/bin/vxdestroy_lvmroot -v -b c3t0d0
       Are you sure about destroying c3t0d0 (imported on VG /dev/vg02) ? YES
