Not knowing how megaraid exports a virtual disk I'm not sure what LUN it might assign, or maybe it presents it as a new ID number instead of a new LUN.

Thanks for all that info! In this situation, I could unload and reload the driver but in future I won't be able to. Looking at that file gives me the following:
[root@host ~]# cat /proc/scsi/scsi Attached devices: Host: scsi0 Channel: 00 Id: 00 Lun: 00 Vendor: ATA Model: ST3160812AS Rev: 3.AA Type: Direct-Access ANSI SCSI revision: 05 Host: scsi1 Channel: 00 Id: 00 Lun: 00 Vendor: ATA Model: ST3160812AS Rev: 3.AA Type: Direct-Access ANSI SCSI revision: 05 Host: scsi2 Channel: 02 Id: 00 Lun: 00 Vendor: LSI Model: MegaRAID 8888ELP Rev: 1.12 Type: Direct-Access ANSI SCSI revision: 05
So I can see echo "scsi add-single-device 2 2 0 0" >/proc/scsi/scsi would have been what I needed, correct? In the future once I start using this system I won't be able to reboot it, so I will get a handle on how this controller adds virtual discs.
Shame there isn't a way to simply rescan the bus without knowing what you are expecting:)
Thanks! jlc
