Setting up ONTAP in a MetroCluster configuration with array LUNs
After connecting the devices in the MetroCluster configuration, you must set up the ONTAP systems to use the storage on the storage array. You must also configure any required ONTAP feature.
Verifying and configuring the HA state of components in Maintenance mode When configuring a storage system in a MetroCluster configuration, you must make sure that the high-availability (HA) state of the controller module and chassis components is mcc or mcc-2n so that these components boot properly.
Configuring ONTAP on a system that uses only array LUNs
If you want to configure ONTAP for use with array LUNs, you must configure the root aggregate and root volume, reserve space for diagnostics and recovery operations, and set up the cluster.
Setting up the cluster
Setting up the cluster involves setting up each node, creating the cluster on the first node, and joining any remaining nodes to the cluster.
Configuring FC-VI ports on a X1132A-R6 quad-port card on FAS8020 systems
If you are using the X1132A-R6 quad-port card on a FAS8020 system, you can enter Maintenance mode to configure the 1a and 1b ports for FC-VI and initiator usage. This is not required on MetroCluster systems received from the factory, in which the ports are set appropriately for your configuration.
Assigning ownership of array LUNs Array LUNs must be owned by a node before they can be added to an aggregate to be used as storage.
Peering the clusters
The clusters in the MetroCluster configuration must be in a peer relationship so that they can communicate with each other and perform the data mirroring essential to MetroCluster disaster recovery.
Mirroring the root aggregates
You must mirror the root aggregates in your MetroCluster configuration to ensure data protection.
