Troubleshooting For AIX LVM:0516-787

Today,when i extend a lv,i got following errors:

# chfs -a size=80G /oradata
0516-787 extendlv: Maximum allocation for logical volume datalv
        is 960.

From above VG information,the dbvg has enough PPs to use,so you must increase the maximum allocation for logical volume datalv.Calculate the number of LPs needed = LV Size in MB / LP size in MB.Here,i want increase datalv to 80G,so LPs=80G*1024/64=1280.

# chlv -x 1280 datalv
# chfs -a size=80G /oradata
Filesystem size changed to 251658240
