[CentOS] Megraid SAS virtual disc question

[John R Pierce]

ah....  for 2.6 systems (rhel5, etc)...

    # echo “- - -” > /sys/class/scsi_host/hostH/scan

scans for all devices on channel hostH



    # *echo “1” > /sys/class/scsi_host/hostH/device//H:B:T:L//delete
deletes device H:B:T:L from channel hostH

*

**

*
	# echo “/B T L/” > /sys/class/scsi_host/hostH/scan*

adds device B T L to hostH ...

this is for scsi or fiberchannel, AFAIK.
