3928336

Description: In CTYunOS 23.01 , which includes MLNX_OFED drivers as part of the OS repository, the DOCA-HOST repository should be enabled before installation to avoid any installation issues.

Workaround: Run:

            

            
yum --enablerepo=doca install
        

Keyword: CTYunOS; installation

Reported in version: 2.5.2

3631257

Description: When installing DOCA for host on a SLES15.5 system that uses NVMe storage (e.g., NVMe disk) and a non-default kernel that requires rebuilding the kernel, the script doca-kernel-support builds and installs the mlnx-nvme drivers that override standard NVMe kernel drivers, which renders the system unbootable.

Workaround: After installing doca-extra, edit the doca-kernel-extra script before running it to avoid it building mlnx-nvme modules. The option --without-mlnx-nvme must be added to the invocation of install.pl:

            

            
sed -i -e '/install\.pl/a\\t--without-mlnx-nvme \\' /opt/mellanox/doca/tools/doca-kernel-support
        

Keyword: NVMe; SLES

Reported in version: 2.5.0
