Generally, the reasons for E-HPC cluster activation failure in some regions and zones are as follows:
- NAS is not deployed in this region, so shared storage cannot be created for the E-HPC cluster.
- The region and zone do not have the ECS instance type in line with the computing node configuration of the E-HPC cluster (for example, no GPU instance).
- The region and zone do not have sufficient resources for creating the nodes required by the E-HPC cluster.
Select another region for cluster creation if you have no special requirements.
