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.
Check if any VMs are using the storage from the cluster. It is recommended to power off the VMs before powering off the cluster.
When the cluster is powered off, you have no access to the UI, 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
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
NOTE:TLC flash drives retain data for up to 90 days while powered off. Data corruption may occur if the drives are powered off for more than 90 days or if they are stored in temperatures above 40° C (104° F).
NOTE: QLC flash drives retain data for up to 30 days while powered off. Data corruption may occur if the drives are powered off for more than 30 days or if they are stored in temperatures above 40° C (104° F).
Steps
In
PowerStore Manager, select the
Settings icon, and then select
Power Down in the
Cluster section.
Click
Power Down Cluster.
The
Validation window opens.
Click
Perform validation.
Review any errors, warnings, and recommendations. If the cluster passes all the validation checks, click
Next. If there are remaining errors that can safely be ignored, select
Ignore errors and proceed, regardless of possible data loss, and then click
Next.
The
Active Objects window opens.
Review the list of objects on the appliance that had I/O activity during the last five minutes.
Click
Next.
The
Confirm window opens.
Enter the service password, and click
Power Down.
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.
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.
Disconnect the power cables from each of the associated expansion enclosures to power them down, if required.
If your cluster has more than one appliance, repeat the previous two steps to disconnect power from the remaining appliances in the cluster.
