Upgrading the firmware using the parallel method
In a parallel firmware upgrade, firmware on all the nodes is upgraded simultaneously. During parallel upgrade, you must shut down the cluster. Ensure that all the nodes are shut down, and then upgrade the firmware on all the nodes simultaneously.
To upgrade the firmware using the parallel method:
- To shut down all the nodes, log in to the cluster-level CLI by logging into the system using the console IP address with your credentials, and then run the cluster node shutdown nodename=all command.
- 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 file, click the Disk icon on the top of the screen, click CD/DVD > Local *.iso file and select the ISO file.
Note:
A separate mount point for the firmware package is required for each node. For example, for a four-node cluster, create four different mount points and attach the firmware package separately.
Ensure that the media is uploaded successfully.
- Restart all the nodes. Click the iLO icon and click Power > Momentary press.
After the nodes are restarted, the nodes are expected to reboot from the mounted firmware package. Monitor the ILO console for all nodes, and if any node fails to boot from the firmware package and instead boots from the HDD containing the NetBackup Flex Scale software, perform the following steps on that node immediately:
Reset the ILO.
Unmount and remount the firmware package.
Reset the node from the ILO.
- 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 returns to the login window automatically once the firmware upgrade is done.
- Verify that 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.
- Update the
acl_info.jsonACL file on the nodes.See ACL configuration.
