Upgrading SANtricity OS Software on the storage controllers

You might need to upgrade the SANtricity OS Software on the storage 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.

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 storage 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

  1. 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 node.
    3. Select the Tasks tab.

      Maintenance Mode button for appliance
    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.

  2. From a service laptop or management client, access SANtricity System 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 Upgrading SANtricity OS guide or the SANtricity System Manager online help to upgrade the firmware and NVSRAM.
    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:
