A Fail-Safe Network (FSN) should be created when the Top-of-Rack (ToR) switches have not been configured with an MC-Lag interconnect. An FSN extends link failover into the network by providing switch level redundancy. An FSN can be configured on a port, a link aggregation, or any combination of the two.
Steps
Select
Hardware > [Appliance] > Ports.
If you plan to use aggregated links for the FSN, first create the Link Aggregation Groups. For details, see
Create LACP bonds for NAS traffic.
From the list, select two ports or two link aggregations, or a combination of a port and a link aggregation group that you want to use for the FSN on node A and select
FSN > Create FSN.
In the
Create FSN panel, select which ports or link aggregation to use as the primary (active) network.
NOTE:The primary port cannot be modified once it is used to create a NAS server.
Optionally, add a description of the Fail-Safe Network.
Click
Create.
PowerStore Manager automatically creates a name for the Fail-Safe Network using the format: "BaseEnclosure-<Node>-fsn<nextLACPbondcreated>"
BaseEnclosure is constant.
Node is the node that is displayed in the
Node-Module-Name list.
nextLACPbondcreated is a numeral value that is determined by the order in which the bond was created in
PowerStore Manager, starting with zero for the first created bond.
The first FSN created in
PowerStore Manager on node A would be named BaseEnclosure-NodeA-FSN0.
The same FSN is configured on the opposite node. For example, if you configured the FSN on node A, the same FSN would be configured on node B.
