RHEL6 不重启扫描新添加硬盘

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.
