Upgrading SANtricity OS Software on the E2800 controller using maintenance mode

For storage controllers currently using SANtricity OS older than 08.42.20.00 (11.42), you must use the maintenance mode procedure to apply an upgrade.

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 NetApp technical support to confirm you need to update the SANtricity OS, and you know which version you need.
You must have the Maintenance permission.
You must be signed in to the Grid Manager using a supported browser.

About this task

Before you can apply a SANtricity OS Software upgrade, you must place the E5700SG controller into maintenance mode, which interrupts the connection to the E2800 controller. 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.

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 might cause data unavailability, depending on your deployment model and ILM policies.

Procedure

If the StorageGRID appliance is running in a StorageGRID system, place the E5700SG controller into maintenance mode.
1. From the Grid Manager, select Nodes.
2. From the tree view of the Nodes page, select the appliance Storage Node.
3. Select the Tasks tab.
4. Click Maintenance Mode.
  A confirmation dialog box appears.
5. Enter the provisioning passphrase, and click OK.
  A progress bar and a series of messages, including Request Sent, Stopping StorageGRID, and Rebooting indicate that the appliance is completing the steps for entering maintenance mode.
  
  When the appliance is in maintenance mode, a confirmation message lists the URLs you can use to access the StorageGRID Appliance Installer.
6. 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 E2800 controller's 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.
  During the reboot, the following screen appears:
  
  The appliance reboots and rejoins the grid. This process can take up to 20 minutes.
3. On the Nodes page, verify that the appliance node returns to the expected status by viewing the icon to the left of the node name.
  When the reboot is complete, the Tasks tab looks like the following screenshot:
