Replacing the E2800 controller

You might need to replace the E2800 controller if it is not functioning optimally or if it has failed.

• You have downloaded the instructions for replacing the simplex configuration of a failed E2800
controller canister.

perform a specific step. Do not rely on the E-Series instructions to replace a controller in the
StorageGRID appliance, because the procedures are not the same.

replacement procedure, which include downloading and installing E-Series SANtricity Storage

key.
• You must have specific access permissions. For details, see the instructions for administering
StorageGRID.
• You must be signed in to the Grid Manager using a supported browser.
About this task
You can determine if you have a failed controller canister in two ways:
• The Recovery Guru in SANtricity System Manager directs you to replace the controller.
• The amber Attention LED on the controller is on, indicating that the controller has a fault.
The appliance Storage Node will not be accessible when you replace the controller. If the E2800
controller is functioning sufficiently, you can place the E5700SG controller into maintenance mode.
Putting a StorageGRID appliance into maintenance mode might make the appliance unavailable for
remote access.
When you replace a controller, you must remove the battery from the original controller and install it
in the replacement controller.
Note: The E2800 controller in the appliance does not include a host interface card (HIC).
Steps
1. Follow the instructions in the E2800 controller replacement procedure to prepare to remove the
controller.
You use SANtricity System Manager to perform these steps.
a. Make a note of which version of SANtricity OS software is currently installed on the
controller.
b. Make a note of which version of NVSRAM is currently installed.
