Question about Linux HBA driver verion upgrade

[Gary L]

Stupid machine and Kernel.

Just now, I gave kernel 2.4.21-27.ELsmp the last chance: boot from it see if it has something change, if no then remove it. Do you believe it, so far ELsmp run good, no error, no reboot, SAN devices are all good...

What's going on?

Hi Don

As you know, we have over 10 SAN linux servers, just one has the 2.4.21-50 kernel installation ( I have no idea what's happened on it and by whom ). yes, it meets the min requirments of the HBA driver upgrade. I have already upgraded it complelete to 7.07.05.02. Rest of the SAN server, I think I will give up driver update because the OS version too low and update risk is too high, like above case. Upgrade doen't work but server crashed ( atuo reboot every 2 min).

Thanks for your kindly help.

Have a great day.

Gary -
I am not positive, but you may be able to upgrade just ONE of the servers to run the current SANSurfer tool, and then install the SANSurfer agents ONLY on the other hosts - and monitor ALL of them from the one server.

But I appreciate your caution. Be sure to read all the compatibility information before trying to upgrade anything else!

Glad I could help in some way...

Thanks for your suggestions.
I will check every release note before do the upgrade task.

Thanks again.

a HBA driver should not update anyhting on the grub.conf which is meant for kernel install/upgarde. So i would say that is a bogus entry. The driver change might on the same old kernel. (Boot thorough the same old kernel; make the grub.conf acordingly)

Interms of kernel upgrade..We rcently upgraded kernel to kernel-smp-2.4.21-53.EL[Red Hat Enterprise Linux AS release 3 (Taroon Update 9)]

Thanks Santhosh

The new entries that added in grub.conf were wrong.
The reason why HBA driver upgrde failure is OS version lower than mini requirements.

I will update the OS first.
