<br><font size=2><tt>Seth -- I just installed RHEL 4 AS, and
the 3w-9xxx is included.  But<br>
I'm suspicious.  I have _really crappy performance on my raid
array<br>
now.  I don't have any numbers with me now, but for example, it
takes<br>
about 20-25 minutes to format a 260G partition.  Read write is<br>
horrible too.  I haven't had time to troubleshoot yet (or contact
RH,<br>
since this box has support).  So the driver is there, but tweaking may<br>
be necessary.<br>

Hi Scott.
 
Can you tell me where i can find the script? 
Becuase in my file is no script to compile.
 
Or do you mean that?
http://www.3ware.com/KB/article.aspx?id=12690
But the question is work that with centos? 

What driver i must create SMP or not and what is the difference
>To build UP module, type:
>make -f Makefile.rh
>The file created is 3w-9xxx.o
>To build SMP module, type:
>make smp -f Makefile.rh
>The file created is 3w-9xxx.smp

And what i must put in to initial the ramdisk on CentOS.

Redhat from the site above 
/sbin/mkinitrd -v -f /boot/init-2.4.21-4.EL.img init-2.4.21-4.EL

Cent OS ??? 
/sbin/mkinitrd -v -f /boot/2.4.21-27.0.2.ELsmp vmlinuz-2.4.21-27.0.2.Elsmp

My kernelversion is 
root at server8 [/boot]# uname -r
2.4.21-27.0.2.ELsmp


And on this site http://www.3ware.com/KB/article.aspx?id=12706 stay that the
drivers will not work with centos.
But i don?t understand WHY. Redhat and Centos has the same architecture or
not?

Maybe anyone can told me what i must do now :) I am very confused.

Thanks for help
Sven

<br>
<br><font size=2><tt>I did it about 6 months ago, but I cant
find the perl script on their site anymore. However, if you download the driver
source for 2.4 kernels there are makefiles in there.</tt></font>
<br>

</tt></font>
<br><font size=2><tt>That should work, just double-check
filepaths. Poking around the makefile doesnt hurt either. In fact, if you run
into spinlock problems(which I did when compiling drivers for CentOS 3), there
are settings which will need to be changed(check 3ware website for symptoms and
solutions, Ive always found the answer I need there).</tt></font>
<br>
<br><font size=2><tt>>But the question is work that with

<br>
<br><font size=2><tt>Im in a farm with a few dozen servers
running CentOS and compiled-from-source 3ware drivers on 9500 cards. Theyve
worked for months, altho this is not the brand new RC1 CentOS
4.</tt></font>

<br>
<br><font size=2><tt>The knowledgebase article you mentions
says there are no drivers available for CentOS. That is correct to the extent
you CAN'T download the drivers you need and just drop them in, like other
OS's. What you CAN do is download the 2.4 source and compile your
own.</tt></font>
<br>
<br><font size=2><tt>As for the website linked in that
knowledgebase article, Ive never tried their driver.</tt></font>
<br>
<br><font size=2><tt>Don't forget to upgrade firmware!
Some of the early versions could do hideous things. 256k block sizes now
supported! w00t!</tt></font>

Kernelversion at this time is
root at server8 [/boot]# uname -r
2.4.21-27.0.2.ELsmp
