Error on Linux Host

This error is captured /var/log messages

scsi: host 0 ch 0 id 0 lun 16384 has a LUN larger than allowed by the host adapter
scsi: host 0 ch 0 id 0 lun 16385 has a LUN larger than allowed by the host adapter
scsi: host 0 ch 0 id 0 lun 16386 has a LUN larger than allowed by the host adapter
scsi: host 0 ch 0 id 0 lun 16387 has a LUN larger than allowed by the host adapter

Solution:1
                    1-Rescan the HBA for the assigned LUNS
                                         echo "- - -" > /sys/class/scsi_host/hostX/scan

                    Here hostX : host0 /host1 /host2 /host4 (HBA port number)

Solution:2

        1. Don't assign the host LUN ID more than 256 in storage . HBA can see only 256 LUNS
