RE: Adaptec SCSI RAID 2000S



I don't think that recompiling the kernel will be an option over here
either, for a number of reasons I don't think are worth going into.

I've now also tried CentOS 5, but get exactly the same behaviour as with
RHEL5.

I did get a response from Red Hat support  (after booting into rescue
mode and generating an sosreport to send to them), which I'll try next:

"It seems that anaconda fails to detect/install  the second stage grub
boot loader, In order to confirm this, could you please try the below
method from grub> prompt,

grub>  root (hd0,0)    -> Then hit Enter key

grub>  kernel /vmlinuz-2.6.18-8.el5 ro root=/dev/VolGroup00/root
-> Then hit Enter key

grub>  initrd /initrd-2.6.18-8.el5.img	 -> Then hit Enter key

grub> boot		-> Then hit Enter key

The above method would try to boot the system in to the default
runlevel.  Update us with your findings."

Just a note, a kernel compilation sounds a lot scarier than it is.
There are not too many steps involved and after you've done it once or
twice, it's quite straight forward.

My controller is an Adaptec SCSI RAID 2000S.  I did try manually
selecting the Aic79xx driver too, but that didn't work at all - was a
bit of a desperate attempt, but hey...

I've logged a support case with Red Hat, so will see if they can maybe
help.

Recompiling kernels...well, I'll have to look into that.  That's way
outside of my current knowledge/experience :)

I see what you mean:  It does appear as if the driver is present, but
something is amiss somewhere.

Thanks very much for your advice.

Johan

Hello,

I recently had a similar problem installing RHEL5.0 on a box with an
Adaptec 7901x controller.

To resolve I had to select "linux noprobe" during the install and
explicitly select the required Drivers. In my case I needed the
following drivers to get the kernel to recognize the scsi device:

I2o_block
Aic79xx (because my controller was a 7901x)  

And also the tg3 (network driver, but didn't work, see below)

After this the kernel could see the scsi driver and enabled me to
install onto the scsi device.
However the same problem then emerged with the network driver and I
couldn't seem to resolve This by explicitly specifying the tg3 driver
during install, so I installed RHEL5 anyway minus network.
To resolve this I downloaded the latest kernel source from kernel.org
and recompiled it enabling both the Requisite drivers for the network
card and the scsi device by compiling the drivers into the kernel Itself
- as opposed to LKM's.

So to summarise, the linux noprobe method allowed me to install the
RHEL5 operating system onto
The scsi device by explicitly selecting the requisite scsi drivers (but
without network), and a kernel recompile of a generic kernel was
necessary to get the network drivers to install as well as the scsi
drivers.

This was as interesting problem that despite logging a job with Redhat,
the problem was unable to be Resolved using the Redhat kernel even
though I also unpacked the initrd image and verified that All the
drivers I needed were indeed contained in the image.

Let me know how you get on, and if you need more help with anything
above.

Regards,
Geofrey Rainey.

I don't think management over here will go for CentOS.  Besides, if
CentOS is the same as Red Hat, I assume that it too will not have the
driver I need..?

Thanks for the suggestion, though!

You should do fine with CentOS5 as a replacement for RHEL5. CentOS is
binary compatible, a clone if you want, of RHEL. Only real difference
(and the one I can care slightly about) is that CentOS has had all the
RHEL-logos etc stripped and that it uses yum for updating instead of
RHEL's up2date and the RHN.

I use CentOS myself for trying out stuff before deploying to our RHEL3/4
machines. So far so good. I also like the fact that CentOS is supported
as long as RHEL is. Redhat will support v5 until 2011?), and since
CentOS is basically the same thing as RHEL, the same will be true for
support and updates for CentOS.

See this thread on the CentOS forums, it might help you decide:
http://www.centos.org/modules/newbb/viewtopic.php?topic_id=3107&forum=35
. 8-)

[off-track]
I used Fedora before to try out stuff before, but thought the fast
update-cycle was a bit too bleeding edge. I searched around a while and
came across CentOS and haven't looked back since.

HTH.
