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
107.
● 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.
● 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 or
cluster requires operations in the associated VMware vCenter server. See the VMware documentation for more information
about the vCenter server commands.
● 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.
○ For a PowerStore T model node, this command reboots the node itself.
○ For a PowerStore X model node, only the PowerStore controller VM gets rebooted.
Once rebooted, the node returns to normal mode.
NOTE: The svc_node service script, with reboot and shutdown arguments, is typically used in the context of
rebooting or powering off a PowerStore T model node.
Use the VMware vCenter server commands to reboot or power off a PowerStore X model node. In PowerStore
X model nodes, running the svc_node service script with reboot or shutdown arguments only affects the
PowerStore controller VM.
Unless specifically directed by your service provider, for PowerStore X model appliances, use the svc_node service
script only for the following purposes:
○ Go out of service mode (reboot argument).
