I just discovered that a new port has been submited already on June
22nd by Gerrit Beine. ports/82512: New port: sysutils/megaraid. I
don't see it in my latest cvsup of the ports tree, so I'm guessing it
hasn't been committed into the tree yet.
Thanks,

I found some interesting information tonight that will help us all
out.

Basically, LSI now supports FreeBSD and 5.4 seems to have the
updated drivers... so what does this mean?
Well, I discovered that the PERC 4e/Di Raid card is the same thing
as the LSI MegaRAID 320-2X. So if you go to www.lsilogic.com and
go to the download section and find the downloads for the "LSI
MegaRAID 320-2x" you will see that there is a "driver" for FreeBSD.
Download this file and unzip the contents. Inside there is a file
called "MegaRC 1.04.zip" Unzip that and you will have a file
called "megarc" make the file executable "chmod +x megarc" and run
the command "./megarc -option"
This will give you some options that you can play with.
So far I've discovered the following useful information:
./megarc -AllAdpInfo
This shows all your supported adapters. In my case it found
the following:
AdapterNo FirmwareType CardType
00 40LD/8SPAN PERC 4/DC
I then did this to display the status/configuration of the controller:
./megarc -dispCfg -a0

Might I say... EXCITING times for Dell SCSI RAID owners

Subject: Dell PowerEge 2850 and RAID
I'd really like to get some concrete information about RAID
management
under FreeBSD/i386 (5.4) on a Dell PowerEdge 2850. I don't have this
machine, but it is looking very likely that a client will be
getting one
and I'd like to have positive things to say about running FreeBSD
on it.
My major concern is how to monitor the RAID status without
resorting to
looking at the LEDs flash on the disks (*). Ideally, I'd like to be
able to run something from a cron job which told me that
everything was
OK. If errors were logged to /var/log/messages or similar, that
would
be a nice plus.
As far as I can tell, the machine could have either an LSI 53C1030
controller or a Dell PERC 4e/Di controller.
For the LSI I can see that it is supported by the mtp driver, but can
find nothing else.
For the Dell PERC 4e/Di (a different LSI, I believe) it seems to be
supported by the amr driver and I have found various references out
there to these working under FreeBSD, but nothing specifically about
monitoring the RAID.
If anyone can provide some concrete information, I'd be grateful. I
have also explored the Dell and LSI sites, but neither appear to
let you
browse their downloads unless you are a registered customer.
Thanks,
--Alex
