FC switch zoning is the process of assigning a set of WWPNs to a zone, which is a group of ports that can communicate with each other. Zoning is required for FC SAN hosts to access LUNs on the SVM. If the zoning is not done correctly, the host might not be able to discover the LUNs or might see LUNs that belong to other hosts. Therefore, FC switch zoning is a possible cause of the issue with SVM eplc_fcp when mapping a namespace to a host. References :- Configure an SVM for FC, Configure FC protocol and FCoE protocol on SVMs with System Manager

The igroup is a logical grouping of initiators that can access a set of LUNs. The igroup must contain the IQNs (iSCSI Qualified Names) or WWPNs (World Wide Port Names) of the initiators that need to access the LUNs. In this scenario, the igroup named “ESX” has the iSCSI protocol and the VMware OS type, but it does not have any initiators listed. This means that the VMware hosts cannot authenticate and connect to the LUNs in the SVM. To resolve this issue, the igroup must be populated with the correct initiators that match the VMware hosts. This can be done by using the igroup add command or the System Manager GUI12. References :- Create an igroup, Add initiators to an igroup

 To configure data-at-rest encryption for your NetApp ONTAP 9.8 cluster without KMIP services, you need to enable onboard key management and cluster-wide FIPS-compliant mode. Onboard key management allows you to use a passphrase to generate and protect the cluster-wide encryption key, which is used to encrypt the disk encryption keys. Cluster-wide FIPS-compliant mode ensures that the encryption algorithms and modules used by ONTAP are compliant with the Federal Information Processing Standard (FIPS) 140-2. These two actions will satisfy the requirements of data security and passphrase protection for your cluster. References :- NetApp Encryption overview, Configure onboard key management, Enable cluster-wide FIPS-compliant mode

To set up a new SnapMirror SVM replication (SVM DR) relationship, you need to have the following SVM subtypes in the source and target clusters:

• The target SVM subtype must be dp-destination, which means that the SVM is a destination for a SnapMirror SVM replication relationship. The dp-destination SVM is a read-only copy of the source SVM and cannot serve data to clients. It can be used for disaster recovery purposes or for cloning data sets1.
• The source SVM subtype must be default, which means that the SVM is a regular SVM that can serve data to clients using various protocols. The default SVM can be the source for a SnapMirror SVM replication relationship, as well as for other types of SnapMirror relationships1.
• The target SVM subtype cannot be sync-destination, as this subtype is used for SnapMirror Synchronous relationships, which are different from SnapMirror SVM replication relationships. SnapMirror Synchronous is a feature that enables zero-recovery point objective (RPO) replication between two volumes on different clusters, while SnapMirror SVM replication is a feature that enables replication of the entire SVM configuration and data between two clusters23.
• The source SVM subtype cannot be sync-source, as this subtype is also used for SnapMirror Synchronous relationships, not for SnapMirror SVM replication relationships23. References :- SVM subtypes, SnapMirror Synchronous overview, About SnapMirror SVM replication.
