Upgrading SANtricity OS Software on the E2700 controller using maintenance mode

If you are unable to upgrade the SANtricity OS Software using the Grid Manager, use the maintenance mode procedure to apply the 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.

About this task

Before you can apply a SANtricity OS Software upgrade, you must place the E5600SG controller into maintenance mode, which interrupts the connection to the E2700 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

  1. If the StorageGRID appliance is running in a StorageGRID system, place the E5600SG 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.

    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.

  2. From a service laptop or management client, access SANtricity Storage Manager, and sign in.
  3. 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.
  4. Follow the instructions in the E2700 and E5600 SANtricity Software and Firmware Upgrade Guide or the SANtricity Storage Manager online help, and upgrade the E2700 controller's firmware, NVSRAM, or both.
    Attention: If you need to upgrade the NVSRAM in the E2700 controller, you must confirm that the SANtricity OS file you downloaded was designated as compatible with StorageGRID appliances.
    Note: Activate the upgrade files immediately. Do not defer activation.
  5. Once the upgrade operation has completed, return the appliance to normal operating mode:
    1. From the StorageGRID Appliance Installer, select Advanced > Reboot Controller.

      reboot controller
    2. Click Reboot Controller.
      During the reboot, the following screen appears:
      Reboot in Progress

      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:
