Node type: OBJECT-TYPE
Type: CucsEquipmentPresence
Access: read-only
Description: Cisco UCS storage:SasExpander:presence managed object property
What is cucsStorageSasExpanderPresence?
This object reports whether a SAS expander is physically detected present, via CucsEquipmentPresence. An admin checks this before investigating any other expander fault, since a "missing" presence value explains all downstream connectivity errors on drives behind it. For example, if drive connectivity is lost chassis-wide, the admin checks this presence value first to see if the expander module was removed.
