This icon is displayed under these conditions:
- The erasure coding topology protection status is vulnerable.
- The erasure coding topology read status is vulnerable.
- Replication is paused for one or more tenants on one or more replication links in the erasure coding topology. This condition is reported only for active topologies.
This icon is displayed under these conditions:
- The erasure coding topology protection status is broken.
- The erasure coding topology read status is broken.
- One or more tenants added to the erasure coding topology have not been added to one or more replication links in the topology. HCP does not report this condition for a tenant until ten minutes after the tenant was added to the topology.
- HCP cannot find one or more replication links that are included in the erasure coding topology.
