In ACI (Application Centric Infrastructure), nodes refer to the individual switches or spine switches in the fabric. When upgrading the software on these nodes, there are several possible upgrade states that a node can be in, depending on the success or failure of the upgrade process.

The two possible upgrade states for a node in ACI are as follows:

  1. Upgrading: This state indicates that the node is currently undergoing an upgrade. During this time, the node may not be fully operational, and traffic may be rerouted through other paths in the fabric. It is important to ensure that the upgrade process is completed successfully before proceeding to the next step.

  2. CompleteOK: This state indicates that the upgrade process has been completed successfully on the node. The node is now fully operational and can resume normal traffic forwarding duties within the fabric.

The other options listed in the question are not valid upgrade states for a node in ACI. Here is a brief explanation of each of these options:

  • CompleteNOK: This option is not a valid upgrade state in ACI. However, it may indicate that the upgrade process has completed but with some errors or warnings. It is important to investigate and resolve any issues that may have occurred during the upgrade process.

  • Failed: This option indicates that the upgrade process has failed on the node. The node may be non-operational or have limited functionality until the issue is resolved.

  • Aborted: This option indicates that the upgrade process was initiated but then aborted before completion. This may occur if there are issues detected during the upgrade process that cannot be resolved or if the upgrade is intentionally aborted for some reason.
