[ILUG] Linux RAID introduction

[Dave Rynne]

)  Then I added two more, initialised them in the BIOS (took poxy ages), and
) then when I booted the machine up, it didn't see a "/dev/sdb" like I'd
) expected. Any ideas what else I've to do ? The relevant dmesg output is:
) 
) scsi2 : Found a MegaRAID controller at 0xe490, IRQ: 18
) megaraid: [Uc77:1.47] detected 2 logical drives
) scsi2 : AMI MegaRAID Uc77 254 commands 16 targs 2 chans 8 luns
) scsi : 3 hosts.
) scsi2: scanning channel 1 for devices.
) scsi2: scanning channel 2 for devices.
) scsi2: scanning virtual channel for logical drives.
)   Vendor: MegaRAID  Model: LD0 RAID1  8568R  Rev: Uc77
)   Type:   Direct-Access                      ANSI SCSI revision: 02
) Detected scsi disk sda at scsi2, channel 2, id 0, lun 0
) 
)  So, it sees 2 logical drives, but only detects one ?

Is the megaraid driver compiled into the kernel or loaded as a 
module ? I've seen similar behavior when the driver was loaded 
as a module but it was able to see all the logical drives when 
compiled directly into the kernel. Meant to investigate a bit
further but never got a chance.
