Power control procedure considerations
Note the following before you get started:
● Powering off a node, appliance, or cluster can take several minutes to complete.
● In a true emergency power off situation, turn the cabinet power switches to the off position to immediately remove power
from the all cabinet components.
● Working with hardware may cause electrostatic discharge that could damage your hardware. Before working with any
hardware, take precautions around handling replaceable units. See Safety precautions for handling replaceable units on page
53.
● If you are relocating or replacing hardware, to help identify associated enclosures when you are ready to cable and power on:
○ Ensure that you make a note of the cabling between enclosures and the appliances. If you used cable labels at the time of
initial installation, reconnecting the cables is easier.
○ Ensure that you also record the Dell service tag numbers of all enclosures in your cluster.
● Nodes in the appliance power on into the same mode they were in before the appliance was powered off. If a node powers
on in service mode:
1. Log in to the appliance from an SSH client.
2. Run the svc_rescue_state clear command to clear the boot mode.
3. Run the svc_node reboot command.
Once rebooted, the node returns to normal mode.
For more information about the service scripts, see the PowerStore Service Scripts Guide.
● If both nodes in an appliance reboot in service mode, always return Node A to normal mode first to avoid management
software conflicts. After Node A is operating normally, you can return Node B to normal mode.
