the latest 3-ware PCI-X cards need a later 3ware driver
variant than centOS and their upstream presently ship. One
installs with the driver disk (dd) option; one may also also
need to make a custom initrd with the altered module. If not
needed at boot time, one may be able to wait and let the usual
module probing call it in as well, when a mount occurs.
I doco the custom mkinitrd part generally at:
http://www.owlriver.com/tips/driver-modules/
I'll turn this piece into another 'tip' when it comes back
around in my email spool.
Additionally it turns out that the sources for the later
3-ware version are available from 3-ware, so that one may
compile and add it to the tree traversed by the depmod, after
moving the unwanted one away to another name:
as root:
... poke around a bit to see what is loaded
335 modprobe 3w-9xxx
336 locate 3w-9xxx
... examine and inventory what is present as to size and
datestamp
337 ls -al \
/lib/modules/2.6.18-8.1.8.el5/kernel/drivers/scsi/3w-9xxx.ko \
/lib/modules/2.6.18-8.1.8.el5/updates/3w-9xxx.ko \
/lib/modules/2.6.18-8.el5/kernel/drivers/scsi/3w-9xxx.ko \
/lib/modules/2.6.18-8.el5/updates/3w-9xxx.ko
338 lsmod | grep 3w
339 rmmod 3w_9xxx
340 lsmod | grep 3w
341 mv \
/lib/modules/2.6.18-8.1.8.el5/kernel/drivers/scsi/3w-9xxx.ko \
/lib/modules/2.6.18-8.1.8.el5/kernel/drivers/scsi/3w-9xxx.ko_
342 depmod -a
as non-root:
273 ls
274 less 3w-9xxx-2.6.16kernel_9.4.1.2.tgz
... this was pulled from the 3-ware support site
275 tar zxf 3w-9xxx-2.6.16kernel_9.4.1.2.tgz
276 ls
277 cd driver/
278 ls
279 make
... the make dies because I needed the 'kernel-devel' package
which was not present for some headers
280 ls
281 less Makefile
282 rpm -qa | grep kernel
283 rpm -ql kernel-headers
284 make
285 sudo yum provides 'source/drivers/scsi'
286 sudo yum -y install kernel-devel
... so I install the build dependency
287 ls
288 make
289 ls
290 history
291 find -name *.ko
... and a new kernel module results:
292 uname -a
which I move into the proper location for the depmod to find:
293 sudo scp ./3w-9xxx.ko /lib/modules/2.6.18-8.1.8.el5/updates/
295 sudo depmod -a
296 sudo /sbin/depmod -a
297 sudo /sbin/depmod -a -v
Then, back as root:
[root@hostname modules]# uname -a
Linux hostname.yyy.lan 2.6.18-8.1.8.el5 #1 SMP Tue Jul
10 06:39:17 EDT 2007 x86_64 x86_64 x86_64 GNU/Linux
[root@hostname modules]# find -name '3w-9xxx*' | grep '2.6.18-8.1.8.el5'
./2.6.18-8.1.8.el5/kernel/drivers/scsi/3w-9xxx.ko_
./2.6.18-8.1.8.el5/updates/3w-9xxx.ko
[root@hostname modules]#
Note that the last line is the one we just built.
... and all is well, and we verify with a hands off reboot
that it 'just works'
