Fibre Channel Storage System
You receive I/O errors and warnings when you load the Fibre Channel
HBA driver module
The HBA driver, BIOS, or firmware must be updated.
Check the Solution Deliverable List (SDL) on the Dell|Oracle Tested and
Validated Configurations website at dell.com/oracle for the supported
versions. Update as required the driver, BIOS, and firmware for the
Fibre Channel HBAs.
Operating System
When you add a new peripheral device to your Dell PowerEdge system,
the operating system does not recognize the device
The problem occurs when Kudzu is disabled.
Run Kudzu manually after you add the new peripheral to your system.
Using Dell DKMS Drivers After Upgrading the Kernel
If the kernel is upgraded in a system where the DKMS driver is installed, then
after the kernel upgrade perform the following procedure to ensure that the
updated DKMS driver is installed for the latest kernel.
•
If the module version of the updated kernel is higher than the dkms driver
version, then continue using the native driver.
•
If the module version in the updated kernel is lesser than the DKMS driver
version, then use the DKMS driver. Create a file in /etc/depmod.d with the
filename dkms_module_name.conf with an entry as below:
override module_name kernel_version
modules_directory
For example, for the bnx2 driver, create a file bnx2.conf in /etc/depmod.d/
with the below contents:
override bnx2 2.6.18-x.el5 weak-updates
Run the depmod -a command
For more information on DKMS, see the DKMS main page on your system.
