If working in Azure, review the following document describing how to attach a second disk to an instance.

https://docs.microsoft.com/en-us/azure/virtual-machines/linux/attach-disk-portal

Create /datakeeper Folder

Check the Available Disks on node-a

Confirm the disk to mount using lsblk. As seen in the screenshot below, the storage device sdc is not mounted to the instance yet.

Use parted to prepare the partition, then use mkfs to prepare the file system.

Run lsblk again, now /dev/sdc1 should be available to mount.

Now you are ready to create the Data Replication Resource using LifeKeeper / DataKeeper.
