Hereby i post the new version of the HBA auto lunbalancing script version 2.1
It doesn't matter if you have 2 4 6 or 8 storage paths to your LUNs this will balance it automaticly for you to spread the load.

It doesn't matter if you have 2 4 6 or 8 storage paths to your LUNs this will balance it automaticly for you to spread the load.
for PATHS in 2 4 6 8
do
STPATHS=${PATHS}
COUNTER="1"
for LUN in $(esxcfg-mpath -l | grep "has ${STPATHS} paths" | awk '{print $2}')

COUNT=`expr ${COUNTER} + 1`
COUNTER=${COUNT}
if [[ ${COUNTER} -gt ${STPATHS} ]]
then
