RE: Adaptec SCSI RAID 2000S

Dear all,

Please help.

I can successfully complete the installation by doing 'linux noprobe' and manually choosing the i2o block device driver, but afterwards I only get 'GRUB' on the display. If I boot into rescue mode, I have to do 'linux noprobe rescue' and again manually select the i2o driver, otherwise no file system is found to be mounted under /mnt/sysimage. Then I can do 'lsmod' and see that the i2o driver does appear to have loaded:

i2o block
i2o_core i2o_block

And modprobe.conf lists the driver:
alias scsi_hostadapter i2o_block

I was thinking that if it's a problem with grub, then maybe I can try to install LILO instead. But there's no option to do that while installing RHEL5. Does anyone know how I can do this?

Otherwise, it will be acceptable if I can boot in some other way, e.g. from floppy. But the problem seems to lie with the driver not loading...so I'm not sure it that will help at all.

https://bugzilla.redhat.com/show_bug.cgi?id=159043 mentions the same kind of problem, but under RHEL4. I tried it anyway, but it doesn't work for me.

Do you need help?

In the meantime I will try CentOS, just in case it works.

Does anyone have any other suggestions?

Thanks very much.

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. [on-track]

HTH.
