Upgrading the firmware using the rolling method
In a rolling firmware upgrade, firmware on each node is upgraded successively. When you upgrade the firmware, ensure that the node that you upgrade has joined the cluster and the data rebuild is complete.
During a rolling upgrade, you must shut down the node on which you want to upgrade the firmware. After you upgrade the firmware, wait for the node to be resynced before upgrading the firmware on another node.
To upgrade the firmware using the rolling method:
- Sign in to the NetBackup Flex Scale web UI and in the left pane click Cluster Management > Infrastructure.
- Shut down the node for which you want to update the firmware. Click the Actions menu (vertical ellipsis) from the right side of the row in the UI and click Shutdown node.
- When prompted for confirmation, click Shutdown node.
Wait for the shutdown process to complete.
The task is shown completed in Recent activity.
- Verify that the node is shut down. A blank screen is displayed and the Power button turns yellow.
- Log on to HPE-Integrated Lights-Out (iLO) remote console from a Windows system that can access the cluster nodes and on which the firmware package is downloaded from the Download Center.
Note:
The network connectivity between the jump server (Windows system) containing the firmware package and the NetBackup Flex Scale cluster nodes should be stable and reliable to ensure the firmware upgrade process progresses successfully.
- In the left navigation pane click Remote Console & Media.
- Click HTML5 Integrated Remote Console.
- In the console, wait until no messages are displayed and the screen is blank. Set up CD/DVD drive option as a first boot option and then upload the firmware package and restart the node.
To upload the firmware package, click the Disk icon on the top of the screen, click CD/DVD > Local *.iso file and select the firmware package.
Ensure that the media is uploaded successfully.
- Restart the node. Click the iLO icon and click Power > Momentary press.
- From the Smart Update Firmware Boot Menu utility, the Automatic Firmware update mode option is selected by default.
Note the flashing firmware image in the iLO.
During the upgrade, several components are upgraded. Several times, the GUI reports that the firmware update is complete but wait till all components are upgraded. At one point the iLO firmware is upgraded and you are logged out and you need to log in to the iLO again.
You can monitor the progress in the remote console. Ignore the status in the main ILO screen. At a few points during the upgrade an option to reboot the node is shown. Do not reboot the node.
Continue to monitor the progress in the remote console.
It takes approximately 40 minutes to upgrade all the components. After the upgrade is complete, the remote console shows the logs momentarily before rebooting the node automatically. Wait until iLO returns to the login window. It will return to the login window automatically once the firmware upgrade is done.
- Verify the firmware version of the components is updated as per the ACL file on SORT. Click Firmware & OS Software tab > Firmware and review the firmware version of the components.
After the firmware upgrade is complete, the node restarts automatically and rejoins the cluster. Wait for the data rebuilding to complete before you upgrade the firmware of another node in the cluster. During data rebuilding, the node is shown as unhealthy on the GUI. You can view the disk resync status by navigating to Infrastructure > Disks. After the resync is complete, the node is marked as healthy.
- Update the
acl_info.jsonACL file on the nodes.See ACL configuration.
