Replace Both Storage Controllers in Succession

The storage controllers in a dual-controller storage system can be replaced one at a time without shutting down the storage system.

1. Ensure that all the cables connected to the storage controller are labeled.
2. Disconnect the cables from the left storage controller.
3. Remove the battery from the left storage controller.
4. Squeeze the release lever on the top storage controller and pull the release lever away from the chassis.
   NOTE Wait until all the storage controller indicators are off before removing the storage controller.
5. Grasp the release lever, and pull the storage controller away from the chassis.

   

   1. Storage controller
   2. Release level

   CAUTION To prevent a thermal shutdown of the storage system, a storage controller must be replaced within three minutes of it being removed.
6. Locate the battery removed earlier, and insert it into the replacement storage controller.
   1. Align the battery with the slot on the storage controller.
   2. Slide the battery into the storage controller until the release tab clicks into place.
7. Insert the replacement storage controller into the chassis until it is fully seated.
8. Reconnect the cables to the storage controller.
9. Push the release lever toward the chassis until it clicks into place.
   The storage controller is powered on.

   NOTE When a storage controller is powered on, a one‐minute delay occurs while the storage controller prepares to boot. During this time, the only indication that the storage controller is powered on are the LEDs on the storage controller. After the one‐minute delay, the fans and LEDs turn on to indicate that the storage controller is starting up.
10. In the Dell Storage Manager Client, ensure that the replacement storage controller is recognized and the status is Up.
    NOTE If the Storage Center software on the replacement storage controller is older than the software on the existing storage controller, the storage system updates the replacement storage controller with the software version on the existing storage controller. The Storage Center software update on the replacement storage controller could take 15 to 45 minutes to complete.
11. Clear the swap status for the temperature sensor and I/O module.
    1. Click the Hardware tab.
    2. In the Hardware tab navigation pane, expand the enclosure.
    3. Select Temperature Sensors.
    4. In the right pane, right-click the sensor, and then click Request Swap Clear.
    5. Select I/O Modules.
    6. In the right pane, right-click the module, and then click Request Swap Clear.
    7. Click the Alerts tab.
    8. Right-click the alerts for the temperature sensor and I/O modules, and select Acknowledge.
       NOTE The alerts may not appear immediately. If the alerts do not appear, wait 10 seconds and then click Refresh.
12. Shut down the other storage controller in the storage system and repeat the previous steps to replace it.
