I needed a new server, and management found me an X4100 at a garage sale. Not a bad server, but it's been EOLed by Sun, and Sun either never shipped mpt tools with the box, dropped support, or they got tossed in the dumpster when Oracle moved in.

Anyway, you will probably want to monitor your LSI MPT raid if you find one, so here's how to do it if your distro does not come with the "mpt-status" command:

- Obtain mpt-status from http://freshmeat.net/projects/mptstatus/

- Obtain the X4100 resource CD from Sun. You may have to pay for this. Hopefully you got one with your box. I have an ISO file called X4100_X4200_ResourceCD_4.

- Install the mpt driver from the RPMs on the CD: mptlinux-4.00.05.00-1-rhel5.x86_64.rpm

- Activate the mptctl driver (your distro should have come with mptbase and mpt sas): "/etc/rc3.d/S99fusion.mptctl start". Set up an rc3.d link to start this driver on boot!

- You should see mptctl, mptsas, mptscsih (maybe), and mptbase in the output of lsmod at this point. If not, keep hunting for drivers.

- Also on the Sun CDROM is mptlinux-4.00.05.00-src.tar.gz. Create the directory and extract this source into /tmp/mptlinux-4.00.05.00-src.

- Extract the mpt-status source into /tmp/mpt-status-1.2.0.

- Edit the Makefile with:

KERNEL_PATH     := /usr/src/kernels/2.6.18-164.15.1.el5-x86_64/include
CFLAGS          := -Iincl -Wall -W -O2 \
                        -I${KERNEL_PATH} \
                        -I/tmp/mptlinux-4.00.05.00-src/message/fusion

- Make and - it works!
