SCSI Discovery
Hi,
I'm wondering if some one can tell me if this will work or not. I need to add some disk space to a DL380 G5 with SAS. If possible I don't want to shutdown the server. Adding the disks this way I think will work. I'd use the hpacucli to create the mirror but then how do I get linux to discover the new disk without unmounting existing drives, removing the driver and loading it again?
It's running RHES 4 Update 4.
Thanks

Re: SCSI Discovery
Thanks Hasan,
The link was very informative. However I needed to look into dealing with the cciss driver instead of sd devices. In case some one else is interested, you can 'echo "rescan" > /proc/driver/cciss/cciss0'. This will cause the cciss device to rescan it's bus for changes. In my case, when I created the raid set using hpacucli the hardware rescanned on it's own and linux saw the new device. It was ready to go after partitioning and formatting.
