Run compute node health checks prior to upgrading compute firmware
You must run health checks prior to upgrading compute firmware to ensure all compute
nodes in your cluster are ready to be upgraded. Compute node health checks can only be
run against compute clusters of one or more managed NetApp HCI compute nodes.
What you'll need
• You have updated to the latest management services bundle (2.11 or later).
• You are running management node 11.3 or later.
• Your storage cluster is running NetApp Element software 11.3 or later.
Health check options
You can run health checks using NetApp Hybrid Cloud Control (HCC) UI or HCC API:
• Use NetApp Hybrid Cloud Control to run compute node health checks prior to upgrading firmware
(Preferred method)
• Use API to run compute node health checks prior to upgrading firmware
You can also find out more about compute node health checks that are run by the service:
• Compute node health checks made by the service
Use NetApp Hybrid Cloud Control to run compute node health checks prior to upgrading firmware
Using NetApp Hybrid Cloud Control (HCC), you can verify that a compute node is ready for a firmware
upgrade.
Steps
1. Open a web browser and browse to the IP address of the management node:
https://<ManagementNodeIP>/hcc
2. Log in to NetApp Hybrid Cloud Control by providing the storage cluster administrator credentials.
3. Click Upgrade near the top right of the interface.
4. On the Upgrades page, select the Compute firmware tab.
5.
Click the health check
6. On the Compute Health Check page, click Run Health Check.
7. If there are issues, the page provides a report. Do the following:
a. Go to the specific KB article listed for each issue or perform the specified remedy.
b. If a KB is specified, complete the process described in the relevant KB article.
c. After you have resolved cluster issues, click Re-Run Health Check.
After the health check completes without errors, the compute nodes in the cluster are ready to upgrade. See
Update compute node firmware
for the cluster you want to check for upgrade readiness.
to proceed.
