Before upgrading to an HA pair, you must verify that your system meets all requirements and that you have all of the necessary information. |
Before upgrading to an HA pair, you must verify that your system meets all requirements and that you have all of the necessary information.
-
Identify unassigned disks or spare disks that you can assign to the new controller module using the following commands:
-
storage disk show -container-type spare
-
storage disk show -container-type unassigned
-
-
Complete the following substeps:
-
Determine where the aggregates for the existing node are located:
storage aggregate show
-
If disk ownership automatic assignment is on, turn it off:
storage disk option modify -node node_name -autoassign off
-
Remove ownership on disks that do not have aggregates on them:
storage disk removeowner disk_name
-
Repeat the previous step for as many disks as you need for the new node.
-
-
Verify that you have cables ready for the following connections:
-
Cluster connections
If you are creating a two-node switchless cluster, you require two cables to connect the controller modules. Otherwise, you require a minimum of four cables, two for each controller module connection to the cluster-network switch. Other systems (like the 80xx series) have defaults of either four or six cluster connections.
-
HA interconnect connections, if the system is in a dual-chassis HA pair
-
-
Verify that you have a serial port console available for the controller modules.
-
Verify that your environment meets the site and system requirements.
-
Gather all of the IP addresses and other network parameters for the new controller module.
