How to Restart a Dell Compellent Using Dell Storage Manager

Shut Down All Controllers in Storage Center

Shutting down a Storage Center creates a system outage, during which time no I/O is processed. Use this process only as directed, for example to replace hardware, to move the Storage Center to another location, or to shut down for data center power maintenance.

Prerequisites

● An outage must be scheduled so that halting I/O does not impact your network.

● I/O to the controllers must be halted.

Steps

1. If the Dell Storage Manager Client is connected to a Data Collector, select a Storage Center from the Storage view.

2. In the right pane, click Actions→ System→ Shutdown/Restart.

    The Shut Down/Restart dialog box opens. 

3. From the first drop-down menu, select Shut Down.

4. Click OK.

5. After the controllers have shut down, shut down the disk enclosures by physically turning off the power supplies.

Next steps

After the outage is complete, see the Owner’s Manual for your controller for instructions on how to start the controllers in the proper order. 

Restart All Controllers in a Storage Center

If the Storage Center has dual-controllers, the controllers can be restarted in sequence or simultaneously. 

Steps

1. If the Dell Storage Manager Client is connected to a Data Collector, select a Storage Center from the Storage view.

2. In the right pane, click Actions→ System→ Shutdown/Restart.

    The Shut Down/Restart dialog box opens.

3. From the first drop-down menu, select Restart.

4. (Dual-controllers only) From the Restart options drop-down menu, choose how you want the controllers to restart.

    ● To restart the controllers one after the other, avoiding an outage, select Restart in Sequence.

    ● To restart the controllers at the same time, causing an outage, select Restart Simultaneously.

5. Click OK. 

Shut Down a Controller

If the Storage Center has dual-controllers, the remaining controller continues to process I/O. If the Storage Center has only one controller, shutting it down creates an outage.

Steps

1. If the Dell Storage Manager Client is connected to a Data Collector, select a Storage Center from the Storage view.

2. Click the Hardware tab.

3. In the Hardware tab navigation pane, expand Controllers and select the controller.

    The Controller view is displayed.

4. In the right pane, click Shut Down/Restart Controller.

    The Shut Down/Restart Controller dialog box opens. 

5. From the drop-down menu, select Shutdown.

6. Click OK.

2. Click the Hardware tab.

3. In the Hardware tab navigation pane, expand Controllers and select the controller.

    The Controller view is displayed.
