Manually installing the ENA drivers
This manual installation of ENA drivers is required while recovering VMware virtual machines to AWS cloud data center. For recovery from AWS region to AWS region, the source virtual machine in AWS data center might have this driver pre-installed, in such case driver installation is not required.
Steps to manually install the ENA drivers based on the operating system environments:
To install ENA drivers on the Linux operating systems:
Download aws_ena_linux.tar from URL:
Open the archive and navigate to the appropriate Linux distribution.
For example: If you are using Rhel7.0, navigate to the RHEL7.0 folder
Locate the ena.ko file from the distribution folder and copy it on directory of your choice on the workload you want to configure for DR operation.
Execute the following commands where the ena.ko file is located:
sudo cp ena.ko /lib/modules/`uname -r
sudo echo "ena" >> /etc/modules.load.d/ena.conf
sudo echo "nvme" >> /etc/modules.load.d/ena.conf
insmod /lib/modules/`uname -r`/ena.ko depmod
The workload is then ready to perform DR operation.
To enable NVME drivers on Linux:
Ensure nvme driver is listed in initrd folder.
You can use Dracut to update the initrd configuration. Execute the following command:
echo "add_drivers += \" nvme \" " > /etc/dracut.conf.d/ena.conf dracut -f -v
