HWNAS0012I You cannot separate the serverName agentless server because it is already defined on the smallest possible separation boundary.
Explanation
The separation of an agentless server occurs on boundaries that are identified by storage system host connections that have sets of WWPNs that do not overlap. The agentless server that you selected is either based on a single host connection and therefore cannot be further subdivided, or the agentless server is based on multiple host connections that all have overlapping sets of WWPNs assigned.
Action
If the agentless server is based on multiple host connections and you want to separate it, use the GUI or CLI for the storage system to modify the host connection definitions. Remove any unintended overlap between sets of WWPNs for the storage system host connections. After you remove the overlap, rerun the probe on those storage systems. After the probes complete, try to separate the agentless server again.
You cannot eliminate any overlap that is caused by HBAs. HBAs are discovered during the fabric probe, and identify which WWPNs cannot be separated. That is, the HBAs identify which WWPNs are known to belong to the same interface card in a server computer.
