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.
•
If you are relocating or replacing hardware, to help identifying 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 will be easier.
•
Ensure that you also record the Dell service tag numbers of all enclosures in your cluster.
•
Nodes in the appliance power on in the same mode that they were in when 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. Then, run the
svc_node reboot
command to reboot the node and return it 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.
•
A PowerStore X model appliance consists of two ESXi host nodes (node A and node B), running VMware ESXi version 6.7, and a
controller VM on each that runs the PowerStore operating environment. Powering off a PowerStore X model node, appliance, or
cluster requires operations in the associated VMware vCenter server. See the VMware documentation for more information about the
vCenter server commands.
