To scan all SCSI buses for hardware changes enter the following:
echo “- – -” >/sys/class/scsi_host/host0/scan # “dash space dash space dash space”
I did this on CentOS 5 to discover a new disk I added, but did not want to reboot the server.
Note: You might have to use one of the other host directories. In Ubuntu, I had to use host2 before the drive would show up.
Hi, thanks for this, first time iislatlnng CentOS (always been Ubuntu up til now, wanted to try something else). Ran into this problem. installed 3.6 as above via network. 30Mb line. Not too slow at all
