Clustered Data ONTAP procedure to bring system down
1. disconnect and shut down all the connected CIFS/NFS clients 2. if there are any hosts that have FCP or iSCSI-based LUNS, shut them down before shutting down NetAPP 3. for 2-node cluster (useful for us) ::> cluster ha modify –configured false ::> storage failover modify –node * -enabled false for 4 +-node cluster ::> storage failover modify -node * -enabled false 4. halt node : : > system node halt -node trustnetic-cluster-01 -inhibit-takeover true -skip-lif-migration-before-shutdown true -reason "power maintenance" : : > system node halt -node trustnetic-cluster-02 -inhibit-takeover true -skip-lif-migration-before-shutdown true -reason "power maintenance" 5. Physically power down the head, then all the attached disk shelves as needed. 6. Physically unplug the cables from power supplies on the back of the storage systems and shelves, to avoid any electrical issues when external power is restored.
Procedure to bring the system back online
1. Reconnect all the power cables if previously disconnected. 2. Power on core switches. 3. Physically power up all disk shelves first. Wait until 30 seconds after the last disk shelf is powered on, then power on the storage system head so that all disks will be available when they are required by Data ONTAP. 4. Verify the storage system is up, all services are running, and network connectivity is present. 5. For clustered ONTAP systems, check cluster show and storage failover show to confirm CFO/SFO is configured/enabled. - If on version prior to 8.2 in which cluster ha and/or storage failover were disabled, run the following commands: ::> cluster ha modify –configured true ::> storage failover modify –node * –enabled true
Verify and check status
cluster show aggr show lun show system node show vserver show cifs show volume show igroup show cf status system health status show system health subsystem show
