[ILUG] SCSI

[Wynne, Conor]

Does it have a hot-plug drive cage? Just because its on a raid chipset, does
not mean the drives are hot-plug. Be carefull.

Does anybody have any experience of adding/removing a SCSI drive to a
system without rebooting.

This is a system with a RAID controller in it.
So it does support adding drives.

But how do I get Linux to see the drive.

I have found that you can use
echo "scsi add-single-device host channel ID LUN " > /proc/scsi/scsi

The biggest problem I have with this is I'm not sure of the info I need
to put in for host channel ID LUN.

The RAID card I'm using is a PERC QC card as shipped from DELL.

Please note I'm not trying to add a drive to an existing RAID setup.
But an extra drive under Linux.

A second related question can anybody tell me if it is possible to get
Linux to reconise that a Drive has grown in size so there is now space
at the end of a drive.(i.e. if I add an extra drive to a RAID array)

Thanks in Advance for any help.
