hi vince... thank you for the advice.
i did update my ports and install the 1.01.40 version...
i have the linux-base installed and the linprocfs and linsysfs mounted..
but still nothing substantial happening:
# megacli -adpCount
Controller Count: 0.
any other ideas?!
thanks...

sorry for the double posting.... just to update:
i installed also the linux-megamgr same result:
Failed to open driver node /dev/megadev0
after linking megadev0 to mfi0 it can not see the version... it gets
more and more pathetic by the minute...
odd that it wouldnt install as it did for me just now. Is your ports
tree up to date? I'm guessing not since the latest version reference in
ports is 1.01.40 and you found and got the 1.01.09 rpm/zip
try updating your ports to the latest tree (portsnap is my method of
choice but csup works fine too :) then try
cd /usr/ports/sysutils/linux-megacli && make install clean
Be sure to pay attention to the post-install message as it tells you
about whats needed in the way of kernel modules and sysctl variables as
well as what periodic config is available.
We do have a server at work using the LSI Logic / Symbios Logic MegaRAID
SAS 1078 which hosts 40 VPS's running quite happily in a RAID 1+0
config, each VPS running web/mail/ftp for a number between 1 and 100
websites, so they seem to perform well enough, this is a linux server
though.
If you've been sold a RAID1 array i'd imagine thats what you have
unless you have reason to believe otherwise. It will appear as a singe
block device (/dev/mfid0) to the operating system though as you have see.

thanks Vince... i didnt wanted to install the linux base because a
lot of kids will be running some 'cool' boards or blogs that probably
have cool linux holes too. but just for the hell of it and for he
purpose to get to the controller i did. it took a while to find the
Linux_MegaCli_1.01.09.zip. it's not on the freebsd site and not on the
LSI site (anymore) either.. anyway after a lot of rpm downloads and
patching and variable changing and fs mountings i get this:
# /usr/local/sbin/megacli -adpCount
ERROR:Could not detect controller.
Controller Count: 0.
pretty neat system...
now what?!

?!?!?! does that mean that there is no raid? why then the df
output? the machine is supposed to have 4 250gig SAS drives.
Its more likely that megarc doesnt support the newer controllers
which is a shame. you might have more luck with
sysutils/linux-megacli since that explicitly mentions LSI MegaRAID
SAS, I wish they would make the util open source though. Will mean
you need the linux-base port installed and linux.ko loaded.
A RAID1 config shoudl suit a busy webserver well.

hi all...
a hosting facility build a new dedicated server for me and looking
at the dmesg i see:

i asked for raid1. i cant find too much information about the mfi
driver. just that it works with freebsd 7.
you might want to look at sysutils/megarc and possibly
sysutils/linux-megamgr so you can more closely monitor/investigate
your array.
Vince
i'll keep looking but - has anybody successfully deployed
production servers using the LSI MegaSAS 1078 in RAID1 on a very
busy web server?
is there any loss in performance using that hardware in RAID1?
any performance loss in RAID1 at all?
thanks...
