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.
