Cluster::*> storage shelf show -connectivity -shelf *
Errors:
------

- Controller chassis environmental information is not being polled and displayed by ONTAP. Consequently, this leads to the absence of EMS events triggering and the failure of shelf maintenance requests, such as the retrieval of shelf logs.
