Power off a node using a service script

Prerequisites

Obtain the following information:
  • Management IP address of the appliance that contains the node. In PowerStore Manager, go to Settings > Networking > Network IPs > Management. Review the Management IPs table to identify the management IP address associated with the appliance.
  • Service account credentials
NOTE:Do not power off or reboot a node, if the peer node is not operating normally. If the peer node is experiencing any major issues, associated alerts and events appear in PowerStore Manager.

Also, to avoid service interruptions, ensure that there are sufficient and healthy paths from all connected hosts to the peer node.

About this task

NOTE:TLC flash drives retain data for up to 90 days while powered off. Data corruption may occur if the drives are powered off for more than 90 days or if they are stored in temperatures above 40° C (104° F).
NOTE: QLC flash drives retain data for up to 30 days while powered off. Data corruption may occur if the drives are powered off for more than 30 days or if they are stored in temperatures above 40° C (104° F).

Steps

  1. Launch an SSH client, and connect to the appliance using the management IP address.
    NOTE:External SSH management access must be enabled on the appliance.
  2. Enter the username and password that is associated with the service account, and log in.
    The login prompt indicates the node that you are logged into. For example, the letter "A" in the prompt [SVC:user@DST5467-A~]$ indicates that you are logged into node A.
  3. Based on the node you are logged into, run one of the following commands:
    • svc_node shutdown local to power off the node you are logged into.
    • svc_node shutdown peer to power off the peer node.

Next steps

To verify that the node has powered off, check the status of the LEDs in the rear of chassis. Other than the LEDs for the power supply unit, management port, and service port, all LEDs on the node must be OFF. The Unsafe to Remove LED on the active or peer node is ON.
