Upgrading SANtricity OS Software on the E2800 controllers

You might need to upgrade the SANtricity OS Software on the E2800 controllers, if the controllers are not functioning optimally.

Before you begin

Attention: Do not upgrade the SANtricity OS Software or NVSRAM in the E-Series controller unless directed to do so by technical support. Without the guidance of technical support, your StorageGRID appliance could become inoperable. Technical support will help you consult the NetApp Interoperability Matrix Tool (IMT) to determine which versions of SANtricity are compatible with your appliance.

You have contacted technical support to confirm that you need to upgrade the SANtricity OS Software or NVSRAM and to obtain the compatible files.
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

Before you can apply a SANtricityOS Software upgrade, you must place the SG6000-CN controller into maintenance mode, which interrupts the connection to the E2800 controller. Putting a StorageGRID appliance into maintenance mode might make the appliance unavailable for remote access.

Attention: Do not upgrade the SANtricity OS Software or NVSRAM in the E-Series controller on more than one StorageGRID appliance at a time. Doing so may cause data unavailability, depending on your deployment model and ILM policies.

Steps

If the StorageGRID appliance is running in a StorageGRID system, place the SG6000-CN controller into maintenance mode.
1. From the Grid Manager, select Nodes.
2. Select the appliance Storage Node.
3. Select the Tasks tab.
4. Click Maintenance Mode.
  A confirmation dialog appears.
5. Enter the provisioning passphrase, and click OK.
  A confirmation message lists the URLs you can use to access the StorageGRID Appliance Installer while the controller is in maintenance mode.
6. Wait a few minutes for the controller to reboot into maintenance mode. Then, browse to any of the URLs displayed.
  Note: If possible, use the URL containing the IP address of the appliance's Admin Network port.
  
  Note: Accessing https://169.254.0.1:8443 requires a direct connection to the local management port.
7. Confirm that the appliance is in maintenance mode by noting the maintenance mode message on the StorageGRID Appliance Installer home page.
From a service laptop or management client, access SANtricity System Manager and sign in.
Download the new SANtricity OS Software file and NVSRAM file to the management client.
Attention: The NVSRAM is specific to the StorageGRID appliance. Do not use the standard NVSRAM download.
Follow the instructions in the E2800 and E5700 SANtricity Software and Firmware Upgrade Guide or the SANtricity System Manager online help to upgrade the firmware and NVSRAM.
Note: Activate the upgrade files immediately. Do not defer activation.
Once the upgrade operation has completed, return the appliance to normal operating mode:
1. From the StorageGRID Appliance Installer, select Advanced > Reboot Controller.
2. Click Reboot Controller.
  The appliance reboots and rejoins the grid. This process can take up to 20 minutes.
3. From the Grid Manager, monitor the status of the upgraded appliance Storage Node.
  Verify that the Storage Node returns to the expected status.
