Converting an HA pair to a fabric-attached MetroCluster configuration
With the correct hardware, you can reconfigure an HA pair with DS14mk4 FC disk shelves to a fabric-attached MetroCluster configuration.
- If you are upgrading an existing HA pair to a MetroCluster configuration, you must upgrade disk firmware to the latest version.
After upgrading disk firmware, you must power-cycle the affected disk drives to ensure that they work correctly in a fabric-attached MetroCluster configuration. You can download the latest disk firmware from the NetApp Support Site.
- If you are upgrading a 31xx, 32xx, and 62xx dual controller systems, the resulting upgraded system can only have one controller in each chassis.
If you have a chassis with two controllers, you must move one controller to a new chassis to form the partner node of the MetroCluster configuration. You must also obtain and install the FC-VI interconnect card on both systems.
- For details about this conversion process, see TR-3548, Best Practices for MetroCluster Design and Implementation, at the NetApp Support Site.
- If you are converting an HA pair that has SAS disk shelves to a fabric-attached MetroCluster configuration, see Configuring a MetroCluster system with SAS disk shelves and FibreBridge 6500N bridges at the NetApp Support Site.
- Update Data ONTAP, storage system firmware, and disk firmware, as described in the Data ONTAP Upgrade and Revert/Downgrade Guide for 7-Mode, making sure to shut down the nodes to the boot prompt.
- Remove any ATA drives in the configuration. ATA drives are not supported in a MetroCluster configuration.
- Move the NVRAM adapter and FC-VI adapter to the correct slots for your model, as shown by the Hardware Universe at the NetApp Support Site.
- Determine your switch and general configuration by completing the planning worksheet.
Set up and configure the local switches, and verify your switch licenses, as described in the Fabric-attached MetroCluster Systems Brocade Switch Configuration Guide and Fabric-attached MetroCluster Systems Cisco Switch Configuration Guide.
Note: The configuration and firmware requirements for Brocade and Cisco switches in a MetroCluster environment are different from the requirements for switches used in SAN environments. Always refer to MetroCluster documentation when installing and configuring your switches for a MetroCluster configuration.
- Cable the local node.
Enable the Data ONTAP licenses in the following order:
- cf.mode Set the mode to ha
- cf.remote_syncmirror.enable Set the option to on
Configure the local node depending on the type of HA pair:
If you are converting a... Then... Standard HA pair Set up mirroring and configure the local node. Stretch MetroCluster configuration Configure the local node.
- Transport the partner node, disk shelves, and switches to the remote location.
- Set up the remote node, disk shelves, and switches.
