Power off a PowerStore X 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 www.dell.com/powerstoredocs. • Obtain the following information: ○ Site ID ○ Service tags of the appliances, and if applicable, the associated expansion enclosures ○ Address of the VMware vCenter server associated with the appliance ○ Associated vCenter server account credentials About this task NOTE: In this release, you can only have one appliance in a PowerStore X model cluster. Use the following procedure to power off (power down) a PowerStore X model cluster: Steps 1. Disable support notifications as described in Disable support notifications on page 19. 2. Log in to the associated vCenter server. 3. Shut down the user VMs on both ESXi hosts using vCenter commands. NOTE: Do not manually shut down the controller VMs on the ESXi hosts for the nodes. Controller VMs are automatically powered off when you place the ESXi host for each node in Maintenance Mode (see steps 3 and 4). 4. Place the ESXi host for node A in Maintenance Mode, and wait for the process to complete. 5. Place the ESXi host for node B in Maintenance Mode, and wait for the process to complete. 6. Once the nodes go into Maintenance Mode, shut down the ESXi hosts using the vCenter commands. 7. Monitor the vCenter server console to ensure that the ESXi hosts have shut down. 8. Wait for 5 minutes, and then, if required, disconnect the power cables from the base enclosure and expansion enclosures.

If applicable, for each appliance in the cluster, ensure that expansion enclosures are also reseated into the cabinet. 3. If applicable, for each appliance in the cluster, reconnect the power cables to each expansion enclosure in the following order: • Expansion enclosure 0 • Expansion enclosure 1 • Expansion enclosure 2 Power control procedures 17

Power off a PowerStore X 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

.
•
Obtain the following information:
○
Site ID
○
Service tags of the appliances, and if applicable, the associated expansion enclosures
○
Address of the VMware vCenter server associated with the appliance
○
Associated vCenter server account credentials
About this task
NOTE:
In this release, you can only have one appliance in a PowerStore X model cluster.
Use the following procedure to power off (power down) a PowerStore X model cluster:
Steps
1.
Disable support notifications as described in
Disable support notifications
on page 19.
2.
Log in to the associated vCenter server.
3.
Shut down the user VMs on both ESXi hosts using vCenter commands.
NOTE:
Do not manually shut down the controller VMs on the ESXi hosts for the nodes. Controller VMs are
automatically powered off when you place the ESXi host for each node in Maintenance Mode (see steps 3 and 4).
4.
Place the ESXi host for node A in Maintenance Mode, and wait for the process to complete.
5.
Place the ESXi host for node B in Maintenance Mode, and wait for the process to complete.
6.
Once the nodes go into Maintenance Mode, shut down the ESXi hosts using the vCenter commands.
7.
Monitor the vCenter server console to ensure that the ESXi hosts have shut down.
8.
Wait for 5 minutes, and then, if required, disconnect the power cables from the base enclosure and expansion enclosures.
