What is the proper way to shut down and power on an ONTAP Select cluster?

Graceful shutdown:

1. Sign in to the ONTAP command line interface and halt the node(s).

• Single Node Cluster:

Example:

Single::> halt
(system node halt)
Warning: Are you sure you want to halt node "Single"? {y|n}: y

• Select-HA (two or more node) Cluster:

Example:

HA::> halt -node * -skip-lif-migration-before-shutdown true -inhibit-takeover true -ignore-quorum-warnings true
(system node halt)
Warning: Are you sure you want to halt node "HA-01"? {y|n}: y
Warning: Are you sure you want to halt node "HA-02"? {y|n}: y

2. Check in vCenter and verify the node(s) is/are powered off.

Power on:

1. Prior to booting the ONTAP Select cluster, ensure that the ESXi hosts are healthy (e.g., network ports are up, disks and datastores are fully initialized, and there are no critical/error alerts).
2. Boot up the ONTAP Deploy VM first. This is required because when the ONTAP Select nodes boot up, they need to communicate with the Deploy VM to verify their configuration and licensing status. Additionally, for 2-node HA clusters, the Deploy VM serves as the mediator for storage failover. If the Deploy VM is not available, this process could fail or be delayed.
3. Boot up the ONTAP Select VMs. Once the boot-up is successful, the nodes will reach the login prompt.
4. After the Select nodes are booted, perform a Cluster Refresh using the Select Deploy VM to make sure the powered on Select VMs are recognized correctly.
