My machine has the following configuration:
HP COMPAQ PROLIANT ML350 G3
4 PROCESSORS OF 3057.460 MHz
2 DISKS OF 80 GB
CONTROLLING COMPAQ SMART ARRAY 641 (WITH 256MB OF CACHE)
2 PLATES OF NET BROADCOM NETXTREME GIGABIT
SCSI AHA-3960D/AIC-7899A U160/m
I tried other versions of RedHat, but only the last had drivers for my
controlling SmartArray (other distributions SUSE and CONECTIVA also had
support with Kernel above the 2.6). Conectiva suggests that the option
O_DIRECT fcntl is used instead of rawdevice, but I don't know as using. I
already researched but I didn't find.
Bye,
Urbano.

2 PLACAS DE REDE BROADCOM NETXTREME GIGABIT
SCSI AHA-3960D/AIC-7899A U160/m
Eu tentei outras versões do RedHat, mas somente a última tinha drivers para
a minha controladora SmartArray (outras distribuições SUSE e CONECTIVA
também tinham suporte com o Kernel acima do 2.6). O Conectiva sugere que se
utilize a opção O_DIRECT fcntl ao invés de rawdevice, mas não sei como
utilizar. Já pesquisei mas não encontrei.

Please, could you give the hardware configuration
of your machines ?
What do you really mean with controlled smart array
? We are installing an HP Proliant server connected to
an EMC Storage Area Network and perhaps we could have
the same problem in the next future.
Bye.
