netapp nodes refresh, - need plan

[KD2]

Hello All,

We are planning to do  the netapp node refresh, in our environment, the below steps suggested by some one else, who involved the discussion, but the resource moved out . so need help to complete the task.

1. add the new nodes to the cluster

2. volume migration

3. lif migration

Environment : one cluster 4 nodes, 2 AFF & 2 FAS (refresh to AFF), in the cluster all protocols used (NAS, ISCSI & FC)

Need clarity for the below points:

1. what are the steps need to follow the node addition, after node added to the cluster, data lif  need to create or existing data lifs will migrate

2. what is the steps & pr-requestee need to follow the migrate NAS, ISCSI & FC lif 's

1、This section describes how to configure nodes after a cluster is added

https://docs.netapp.com/us-en/element-software-125/setup/concept_setup_configure_a_storage_node.html 

2、Here are some articles about NAS and SAN migration

https://docs.netapp.com/us-en/netapp-solutions/xcp/xcp-bp-migration-workflow-overview.html 

https://docs.netapp.com/zh-cn/ontap-fli/san-migration/concept_data_migration_program_overview.html

Hope these help you

Best regards.

Preparation:

• Check Cluster Health: Ensure all existing nodes in the cluster are healthy using the cluster show command
• Gather Information: Collect the necessary information for the new node's management LIF, including port, IP address, netmask, and default gateway

.           Power On the New Node:

• Boot the Node: Power on the new node and start the Node Setup wizard

.           Join the Cluster:

• Cluster Setup Wizard: Use the cluster setup command to start the Cluster Setup wizard
• Join Existing Cluster: When prompted, choose to join an existing cluster

.The Above Steps can be referred from the article below.

https://docs.netapp.com/us-en/ontap/system-admin/add-nodes-cluster-concept.html

            Add the Node:

• Add Node Command: Use the cluster add-node command to add the new node to the cluster

.

Data LIFs After Node Addition:

• Existing Data LIFs: Typically, existing data LIFs will remain on their current nodes unless manually migrated. Data LIFs can be migrated to the new no...
• Creating New Data LIFs: If you need to create new data LIFs on the new node, use the network interface create command. Specify the vserver, LIF name, ...

.

Example Command to Create a Data LIF:

network interface create -vserver <vserver_name> -lif <lif_name> -role data -data-protocol nfs -home-node <node_name> -home-port <port_name> -address <IP_address> -netmask <netmask> -firewall-policy data -auto-revert true
