DKMS Considerations for Red Hat Linux
Dynamic Kernel Module Support (DKMS) is required on systems where a precompiled binary kernel module is not available, such as on a
system running a custom Linux kernel.
The HIT/Linux installation script will attempt to install all required Linux packages. However, DKMS is not available in the default Red Hat
repositories; extra steps are required to obtain and install DKMS. All other prerequisite packages are installed.
Note the following considerations:
•
If your system is configured to use the Extra Packages for Enterprise Linux (epel) repository. DKMS is automatically installed by the
HIT/Linux installation script. No further action is needed.
•
To install DKMS manually, download the package from
https://github.com/dell/dkms
. Dell recommends using version 2.2.0.1 or later.
•
To verify if your system is using the correct DKMS version or the prebuilt binary version, enter the following command:
# rpm -q equallogic-host-tools-kernel
•
If the result shows that the equallogic-host-tools-kernel package is installed, then you are using a DKMS-based installation.
•
If DKMS is not installed, entering the
ehcmcli status
command will produce the following error message:
ERROR: dm-switch kernel module is not present Resolution:
Ensure the kernel module package appropriate for your system is
installed, and use 'modprobe -v dm-switch' to verify the module can
be loaded.
•
If DKMS is loaded but contains incompatible module versions (for example, the HIT/Linux
dm-switch
module is still resident in the
kernel), entering the
ehcmcli status
command will produce the following error message:
ERROR: Incompatible version of dm-switch kernel module
detected Resolution: Ensure the kernel module package appropriate
for your system is up to date, and that any conflicting versions
of the 'dm-switch' module are removed.
DKMS requires several other packages:
kernel-devel
,
glibc-headers
,
glibc-devel
,
libgomp
, and
gcc
. The installation script
automatically installs these packages. No further action is required.
