Mpt raid 1 support?

[Moore, Eric Dean]

RAID-1 on the U320 mpt card is a function of the
firmware and hardware.  Under Linux, the mpt
driver is responsding to RAID events, such as if
you insert a drive with safte device, the driver will
do domain validation. But the driver is not having
the raid stack, its in the firmware.

You will need one of the following cards
LSI20320-R,LSI21320-R,LSI22320-R, your host adapter
should be having a sticker saying that.

Firmware download is here:

Step 1: SCSI Host Bus Adapter
Step 2: Ultra 320 Host Bus Adpater
Step 3: LSI20320-R or LSI21320-R or LSI22320-R

The IM or IME firmware is having RAID-1 support.
