RedHat Kernel 2.6.9-42.0.3 qla2xxx_conf warning.

[NIGEL WHITE_2]

I updated the Kernel yesterday using up2date as advised via RHN Erata, and since rebooting the system cant see the SAN??

While installing the kernel I received the following message:
WARNING:No module qla2xxx_conf found for kernel 2.6.9-42.0.3.EL continuing anyway.

What do I have to do to get this new Kernel working off the SAN???

Please help.

Shalom,

I have the very same kernel on a DL380 with qlogic cards.

It sees the SAN just fine.

Hi,

I'm pretty sure we came across this when we upgraded our kernel.

From memory I think you have to reload the packages rpm -Uvh --replacepkgs whatever.rpm
into the new kernel.

We are using emc and powerpath and this worked for us.

Hi,

There may be a problem with the module for the QLogic card.

1) Which SAN storage are you using.
2) Kindly confirm the kernel version.
3) Also confirm the "gcc" version using "gcc -v".
4) Also make sure that you have got the RDAC driver installed.
5) Check with the command -- "dmesg | grep QL".
6) You can also check with "lsmod | grep ql"
7) Check whether you have the module for qla2xxx in "/proc/scsi" directory.

Paul,

Which packages? Kernel or Qlogic packages?

Old Kernel 2.6.9-22.0.2.EL (SAN is fine)

New Kernel 2.6.9.42.0.3.EL (Problems booting)

gcc version = 3.4.6

Found this in the emc documentation.

Upgrading a Linux kernel results in the deletion of the installed
PowerPath drivers.
Red Hat AS/ES 4.0 To upgrade Linux on Red Hat AS/ES 4.0:
1. Install the new errata version.
2. Boot to the new kernel.
3. Reinstall the supported HBA driver.
4. Replace the PowerPath package to copy the PowerPath drivers to the new Linux kernel directory. Use the following command to
replace PowerPath after you have upgraded your Linux kernel:
rpm -Uvh --replacepkgs EMCpower.LINUX-4.5.0-..rpm

Paul,

If this was the case, how does the old kernel boot when I rollback using Grub?

I have discovered a serious flaw with the 2.6.9-42.0.3 kernel and RHCS.

I recommend the following steps:

1) Download the previous kernel 2.6.9.42.0.2 kernel to a local directory.

2) rpm -e this kernel

3) rpm -ivh the one you downloaded.

Reboot.

Thanks again.
