First find your host bus number
grep mpt /sys/class/scsi_host/host?/proc_name
Which should return a line like
/sys/class/scsi_host/host0/proc_name:mptspi
where host0 is the relevant field.
use this to rescan the bus with the following command
echo "- - -" > /sys/class/scsi_host/host0/scan
In the above command the the hyphens represent controller,channel,lun,
so – – – indicates all controllers, all channels and all luns should be scanned.
