B: svc_node shutdown svc_rescue_state clear
C: svc_rescue_state clear svc_node reboot Correct answer
D: svc_rescue_state normal svc_node start
Correct Answer:
C. svc_rescue_state clear svc_node reboot
Explanation

To return a Dell EMC PowerStore node from service mode to its normal operational state, a two-step process is required. First, the service mode flag, also known as the rescue state, must be cleared. This is accomplished with the svcrescuestate clear command, which instructs the node not to enter service mode on its next boot. Second, the node must be rebooted for the change to take effect. The svcnode reboot command performs this restart, allowing the node to boot into normal mode. This specific sequence is the correct and required procedure.

Why Incorrect

A: svcrescuestate start is the command used to enter service mode, which is the opposite of the desired outcome. B: The command sequence is incorrect. The rescue state must be cleared before the node is restarted; shutting it down first is improper procedure. D: svcrescuestate normal is not a valid command. The correct argument to exit service mode is clear.
