We have FAS 8040
Below are the Ports details:
e0a-e0d is a cluster ports
eoe/oe-e0h/0h ports (CNA ports)
e0i-e0l Gigabit Ethernet
Roles of LIFs
Node Management LIF:
This is LIF to manage particular node separarately and this can be configurigure during creating or Joining a cluster.
Example: e0M port is used for this function
This is used to manage entire cluster and its nodes that are associated to the cluster.
These lifs are used for NFS,CIFS,FC,FCOE,ISCSI traffic to their clients and This LIF is associated with a Vserver. Data ports are eoe/oe-e0h/0h ports and e0i-e0l Gigabit Ethernet
This ports are connected to another node in switchless connection or if it is switch based cluster then this ports are connected to the cluster switches and assigns IP automatical in same subnet (we can assign IP address manually when required).
The ports should be used for this role are e0a-e0d.
As per netapp document they mentioned cross-cluster communication, backup, and replication. Intercluster LIFs can be configured on data ports or intercluster ports.
These LIFs can fail over to data or intercluster ports on the same node, but they cannot be migrated or failed over to another node in the cluster.
Now my doubts are
1. What are the intercluster ports in my setup? I need to buy separate cards for this purpose. As per Netapp doc i can also use data ports but i wanted to know whare are intercluser ports.
2. what does cross-cluster communication means?
3. These LIFs can fail over to data or intercluster ports on the same node, but they cannot be migrated or failed over to another node in the cluster. What does this means could you please mention example.
Please also correct me if i understands roles wrongly.
Thanks a lot in advance.
