Create the Fail Safe Network in PowerStore Manager

Once you have configured the ToR switches with the networks required to create a Fail Safe Network (FSN) for NAS, you will need to create the Fail Safe Network in PowerStore Manager.

1. Create the Link Aggregation in PowerStore Manager for the LACP bond you configured on the switch as the primary network in your Fail Safe Network.
   1. From PowerStore Manager, go to the Hardware page and select the appliance for which you configured the bond.
   2. Open the Ports card.
   3. Select the two ports on Node A which were configured for the bond on Node A.
   4. Click Link Aggregation > Aggregate Links.
      PowerStore Manager automatically creates a name for the bond using the following format: "BaseEnclosure-<Node>-<nextLACPbondcreated>" where:

      • BaseEnclosure is constant
      • Node is the node displayed in the Node-Module-Name list.
      • nextLACPbondcreated is the numbered by the order in which the bond was created in PowerStore Manager, starting with 0 for the first created.

      For example, the second LACP bond created in PowerStore Manager on Node A would be named: BaseEnclosure-NodeA-Bond1.

   5. Optionally, provide a Description of the bond.
      It is recommended to put the name of the bond created on the switch that maps to this bond.
      The same LACP bond is configured on the opposite node. For example if you configured the LACP bond on Node A, then the same LACP bond would be configured on Node B.
2. Repeat step 1 for the LACP bond you configured on the switch for secondary network in your Fail Safe Network.
   NOTE: Our example uses an LACP bond for the secondary (standby) network. You can skip this step if you are using a single port for the secondary network.
   The same LACP bond is configured on the opposite node. For example if you configured the LACP bond on Node A, then the same LACP bond would be configured on Node B.
3. Select the Link Aggregations you created in steps 1 and 2, and click FSN > Create FSN.
4. Select the Link Aggregation that will be used as the primary network.
   NOTE: The primary port cannot be changed once is used to create a NAS Server.
5. Optionally, add a description of the Fail Safe Network.
6. Click Create.
   PowerStore Manager automatically creates a name for the Fail Safe Network using the following format: "BaseEnclosure-<Node>-fsn<nextLACPbondcreated>" where:

   • BaseEnclosure is constant
   • Node is the node displayed in the Node-Module-Name list.
   • nextLACPbondcreated is the numbered by the order in which the bond was created in PowerStore Manager, starting with 0 for the first created.

   For example, the first FSN created in PowerStore Manager on Node A would be named: BaseEnclosure-NodeA-FSN0.

   The same Fail Safe Network (FSN) is configured on the opposite node. For example if you configured the FSN on Node A, then the same FSN would be configured on Node B.
7. Create a NAS server with the Fail Safe Network.
   The Fail Safe Network is applied to the NAS server while creating the NAS server in PowerStore Manager. See the PowerStore Configuring NFS Guide or the PowerStore Configuring SMB Guide for detailed steps.
