Replacing controllers System maintenance
Caution: In most cases, replacing an AltaVault controller is performed by NetApp Support. Only experienced technicians should
attempt to replace a controller because of the risk of loosing data.
If you are replacing your AltaVault Controller because of a faulty appliance, NetApp recommends that you preserve
the existing disk cache so that you do not need to download large amounts of data from the cloud, which can be
expensive in terms of time, bandwidth, and costs.
When an AltaVault Controller is replaced by an RMA, you must physically swap the RAID cards between the old
controller and the new one (provided the fault is not related to the RAID card assembly). Since both models are exactly
the same, the total size of the disks remains unchanged. The disks must be installed in order, populating shelf space 1
through 11, they cannot be jumbled.
To preserve your data, ensure that you export the current configuration in your source AltaVault appliance using the
Export Configuration Wizard (choose Settings > Setup Wizard from the management console). NetApp recommends
that you export your configuration and store it in a secure location as a preventative measure against unexpected
failures.
Replacing an AltaVault controller includes the following processes:

“Shutting down and removing the controller from the chassis” on page 61

“Moving working FRUs from the controller” on page 62

“Reinstalling and connecting the controller in the chassis” on page 63
Shutting down and removing the controller from the chassis
Before shutting down the controller, you must export the controller’s current configuration, shut down the controller,
and remove it from the chassis.
To shut down the controller and remove it from the chassis:
1. Ensure that the current configuration from the source appliance has been exported. For details, see the section,
Using the Export Configuration Wizard , in the NetApp AltaVault Cloud Integrated Storage User’s Guide . Ensure
that the exported configuration from the source appliance is safe and accessible.
2. Shut down the source AltaVault appliance by selecting the following from the management console:
a. Select Settings > Reboot/Shutdown.
b. Click Shutdown .
3. If you are not already grounded, properly ground yourself.
4. Unplug the various system cables and SFPs from the controller module. Keep track of where the cables were
connected so that when you reinstall the controller, you can reattach the cables in the same configuration.
