What Should I Do If the On-Premises Cluster Fails to Be Installed?

Symptom 1: Incorrect Binary File Is Used and "./ucs-ctl: cannot execute binary file: Exec format error" Is Displayed

Possible cause: The selected cluster architecture is inconsistent with the CPU architecture of the on-premises cluster node.

Examples:

If the cluster architecture is set to x86 and the on-premises cluster is installed on an Arm node, the installation fails.
If the cluster architecture is set to Arm and the on-premises cluster is installed on an x86 node, the installation fails.

Solution: Cluster nodes do not support heterogeneous architectures. Ensure that the cluster architecture is the same as the CPU architecture of the on-premises cluster node.

If the cluster architecture is set to x86, install the on-premises cluster on an x86 node.
If the cluster architecture is set to Arm, install the on-premises cluster on an Arm node.
