shutdown

Cleanly shuts down an array.

If you shut down an array that is a group member, there is no loss of member, volume, or group configuration information and no loss of volume data residing on the member. Any volumes with data on the array will be set offline until the array is completely restarted. Once the array is restarted, it rejoins the group automatically.

Note: The shutdown command does not power off the array. To power off the array, you must turn off both power supplies after the array shuts down.

Do not repeatedly shut down and restart an array.

To access the CLI to run the shutdown command, see Running Array Management Commands.

Once connected to the array (either through a serial connection to the active control module or a network connection to an IP address assigned to a network interface), press the <Enter> key and log in to a group administration account that has read-write permission (for example, the grpadmin account). At the CLI prompt, enter the shutdown command. After confirming that you want to shut down the array, network connections are closed, and the array is shut down.

If you are using a serial connection, the following message will appear on the console when it is safe to turn off power to both power supplies:

Press any key to reboot.

However, if you are using a network connection to run the shutdown command, the session will be disconnected before the array is shut down. Therefore, confirm that the ACT LED on each control module is off (not lit) before turning off power to both power supplies.

To fully restart the array, turn on power to both power supplies. When the array restart completes, volumes will be set online.

Note: If you physically connect a serial cable to the secondary control module and run the shutdown command, only the secondary control module will be shut down. To shut down both control modules, connect the serial cable to the active control module (ACT LED will be green) and run the shutdown command.

If you have a serial connection to an array that is shut down, but still has power, pressing any key will restart only the active control module. To ensure that both control modules restart, turn off and then turn back on power to the array. Be sure to turn off and turn on both power supplies.

Format

shutdown

Example

In the following example, telnet is used to connect to the array. When you run the shutdown command and confirms the request, the network connection closes:

telnet 123.14.1.132

Trying 123.14.1.132...

Connected to 123.14.1.132.
