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
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.
