What Can I Do If the Pre-upgrade Check of the Cluster Federation Fails?

Context

Before the cluster federation upgrade, UCS checks the cluster federation status, cluster status, and cluster access status to reduce the probability of upgrade failures to the best extend. If any exception is detected, you can rectify the fault by referring to this section. After the fault is rectified, you can upgrade the federation again.

Before upgrading the federation, if any error is reported for the federation status, cluster status, or cluster access status, rectify the fault to prevent the upgrade failure.

Symptom 1: The cluster federation status is abnormal.

Cause: The cluster federation does not run properly.

Solution: Disable the cluster federation and then enable it again. For details, see Enabling Cluster Federation. If the cluster federation cannot be disabled due to service reasons, submit a service ticket and contact technical support.

Symptom 2: The cluster status is abnormal.

Cause: The cluster does not run properly in the fleet or the cluster cannot be accessed.

Solution:

  • If the cluster does not run properly, you can restore the cluster.
  • If the cluster cannot be accessed, add the cluster to the federation again. If the cluster cannot be added to the federation again, submit a service ticket and contact technical support personnel.
