How to check network LIF in CVO-HA Azure and what's their purpose?
Applies to
- Microsoft Azure
- NetApp Cloud Volume ONTAP(CVO-HA)
Answer
- The NIC/port(LIF) on the CVO-HA and usage are as the following:
| Azure Portal | CVO |
| NIC0 | e0a: Management LIF - Use for Cluster/Node management |
| e0a: Data LIF - Used for iSCSI/NFS/CIFS access | |
| e0a: Intercluster IP -Use for SnapMirror | |
| e0a: SVM management IP - Use for SnapCenter | |
| NIC1 | e0b: Cluster network IP -Use for communication between nodes |
| NIC2 | e0c: Cluster Interconnect IP (HA IC) - Use to mirror NVRAM between two nodes |
| NIC3 | e0d: Pageblob NIC IP (disk access) - Use for accessing Blob storage |
- These NIC/LIF info can be checked on BlueXP/Azure portal and CLI:
- BlueXP: Double click CVO->View Additional Information->Access (Only e0a's LIF can be shown)
- Example:
- BlueXP: Double click CVO->View Additional Information->Access (Only e0a's LIF can be shown)
- CLI via SSH CVO:
