Powering off procedures for PowerStore cluster This section includes the following procedures: ● Power off a PowerStore T model cluster on page 16 ● Power off a PowerStore X model cluster on page 16 Power off a PowerStore T model cluster Prerequisites ● Powering off a cluster results in the mapped hosts losing access to the data on the cluster. Before you begin, ensure that you temporarily disconnect host access from all storage resources. ● When the cluster is powered off, you have no access to the GUI, API, or CLI interfaces. Print the power on instructions to ensure that you have the information you require to power on the cluster in a specific order. You can also find these instructions on https://www.dell.com/powerstoredocs. ● Obtain the following information: ○ Management IP address of the cluster ○ Service account credentials ○ Site ID ○ Service tags of the appliances ○ If applicable, service tags of the associated expansion enclosures About this task Use the following procedure to power off (power down) a PowerStore T model cluster: Steps 1. Use one of the following ways to issue a power off command: ● Using PowerStore Manager: a. Select the Settings icon, and then select Power Down in the Cluster section. b. On the confirmation prompt, enter the service password, and then click Power Down. ● Using service script: a. Launch an SSH client, and connect to the appliance using the management IP address. b. Enter the username and password that is associated with the service account, and log in. c. Run the following command to power off the appliance: svc_cluster shutdown 2. Check the status of the process by looking at the Node Power LEDs. The power off process is complete when the Node Power LEDs for all nodes in the cluster are off. 3. After confirming that the cluster has shut down, disconnect the power cables from both nodes in one of the base enclosures in the cluster, if required. Wait a few seconds and confirm that all remaining LEDs have turned off. 4. Disconnect the power cables from each of the associated expansion enclosures to power them down, if required. 5. If your cluster has more than one appliance, repeat steps 3 and 4 to disconnect power from the remaining appliances in the cluster. Power off a PowerStore X model cluster Use the following procedure to power off a single appliance cluster or a multi appliance cluster. Powering off a PowerStore X model cluster is not supported via PowerStore Manager. Prerequisites ● Powering off a cluster results in the mapped hosts losing access to the data on the cluster. Before you begin, ensure that you temporarily disconnect host access from all storage resources. ● When the cluster is powered off, you have no access to the PowerStore Manager, API, or CLI interfaces. 16 Power control procedures

b.
Enter the username and password that is associated with the service account, and log in.
c.
Run the following command to power off the appliance:
svc_cluster shutdown
2.
Check the status of the process by looking at the Node Power LEDs. The power off process is complete when the Node
Power LEDs for all nodes in the cluster are off.
3.
After confirming that the cluster has shut down, disconnect the power cables from both nodes in one of the base enclosures
in the cluster, if required. Wait a few seconds and confirm that all remaining LEDs have turned off.
4.
Disconnect the power cables from each of the associated expansion enclosures to power them down, if required.
5.
If your cluster has more than one appliance, repeat steps 3 and 4 to disconnect power from the remaining appliances in the
cluster.
Power off a PowerStore X model cluster
Use the following procedure to power off a single appliance cluster or a multi appliance cluster. Powering off a PowerStore X
model cluster is not supported via PowerStore Manager.
