AIX increase LP's

Procedure to increase the number of LP's available
Assume we receive an error that the maximum number of LP's had been exceeded, and the maximum number of LP's defined was 1100:

#lsvg , to show the total PP's available in the volume group =1250
#lsvg -l , to show the total PP's used in all logical volumes in that volume group (showed sys1log, the jfs log was using 2 PP's)
#chlv -x 1248 , to change the maximum number of LP's from 1100 to 1248 (1250 PP's in the volume group - 2 PP's used by the jfs log = 1248 available)
