AIX - LVM - Extend Logical Volume

If we want to increase LV size using extendlv command
#lslv newlv

The above command shows LV size, no of LP’s and some other information about LV,
suppose LV has 10 LP’s and usage is up to 95% full,
that time we can increase the LV size online by adding no of LP’s in newlv i.e.

#extendlv newlv 5
After executing the above command 5 PP’s added with newlv,
then some additional space will available in newlv.
Suppose you want to see this changes again use the lslv command

#lslv newlv (it will show no of LV’s is 15 and some additional space)
