To use ANA (Asymmetric Namespace Access) on SUSE Enterprise Linux, it is essential to verify two key components. First, you need to ensure that the ANA driver is installed because it is vital for handling multipath configurations inherent to ANA. Second, verifying the version of ONTAP is crucial as different versions provide varying levels of support and compatibility for ANA functionalities. Ensuring the correct ONTAP version supports ANA under your specific SUSE Enterprise Linux setup will prevent potential configuration and operational issues.
