Using HugeMem kernel with FCA2214 drivers

Has anyone used the Fiber Channel drivers (i.e. hp_qla2x00src-7.07.03p3-19) with RHEL 3.0 HugeMem Kernel?

If so, did you have to re-link the driver?

We use the hp_qla2x00src-7.07.03p4-20 on RHEL 3.0 with a hugemem kernel. Currently we are running on kernel version 2.4.21 errata 47.

The RPM post-install compiles the QLA driver and rebuilds the initrd without problems.
Is that what you mean with relinking?

If you run into errors, please supply some output.

Forgot one details, we have currently running the standard kernel. So when we switch to HugeMem Kernel. I would have to re-install or re-run post-install to create an new initrd.

And if things go wrong and we switch back to the standard Kernel, I would have to re-run the post-install again.

If you got to /opt/hp/src/hp_qla2x00src and use the script compile_all_kernels the QLA driver wil be build for every kernel installed.

After running compile_all_kernels, verify that all modules and initrd's on your system are updated.

You might want to use the following commands:

QLA modules:
find /lib/modules/ -type f -name "qla2300*.o" -exec ls -altr {} \;

Initrd files:
find /boot/ -type f -name "initrd*.img" -exec ls -altr {} \;

(check the output on recent timestamps)

Switching between kernels shouldn't be a problem, because you built the modules and initrd's for all installed kernels.

Excellent!

Thank you very much!
