Entering protected maintenance mode
Use the below procedure to enter protected maintenance mode using PowerFlex Manager.
About this task
PowerFlex Manager does not allow a node to enter service mode in the following scenarios:
- VMware NSX-T or NSX-V is configured.
- PowerFlex Gateway used in the service is being updated on the Resources page.
- Services that do not have switches discovered.
Steps
- Log in to PowerFlex Manager.
- On the Services page, select a service, and click View Details in the right pane.
-
Click
Enter Service mode under
Service Actions.
NOTE The service should have at least three nodes to enter into protected performance maintenance mode using PowerFlex Manager.
-
Select one or more nodes on the
Node Lists page, and click
Next.
NOTE For an environment with Fault set, PowerFlex Manager can put a single node or full fault set in protected maintenance mode. For an environment without Fault sets, PowerFlex Manager can put a four node minimum in protected maintenance mode.
- Select Protected Maintenance Mode.
- Click Enter Service Mode.
- Verify that the node shows as Service Mode (Protected Maintenance) in PowerFlex Manager.
