I have an linux server with an LSI MegaRaid 320-2X SCSI Controller. It works fine and I have a bunch of disks being used by the operating system so the card and driver works fine.

I have added some new disks, initialized them etc and the lsi management software can see the disks and regards them as online, but the operating system cannot see them

There is not much point in having a hot-swap controller if the operating system can't make use of of though.

Is there any way to force the operating system to see the new disks...?
