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.
•
You have labels to identify each cable that is connected to the controller.
•
If all drives are secured, you have reviewed the steps in the simplex E2800 controller
replacement procedure, which include downloading and installing E-Series SANtricity Storage
Manager from the NetApp Support Site and then using the Enterprise Management Window
(EMW) to unlock the secured drives after you have replaced the controller.
Attention: You will not be able to use the appliance
until you unlock the drives with the saved 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. Before changing the link configuration, you must place the E5700SG controller 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.
c. If the Drive Security feature is enabled, be sure a saved key exists and that you know the
pass phrase required to install it.
Attention: Possible loss of data access – If all
drives in the appliance are security enabled, the
new controller will not be able to access the
appliance until you unlock the secured drives
using the Enterprise Management Window in
SANtricity Storage Manager.
d. Back up the configuration database.
If a problem occurs when you remove a controller, you can use the saved file to restore
your configuration.
e. Collect support data for the appliance.
