This is a true/false flag showing whether one capability-catalog provider entry -- one row of the UCS hardware/firmware capability catalog describing a specific adapter, controller, or component model and what it supports has been marked obsolete in the capability catalog and should no longer be used for new configuration. When this flag flips to true for a catalog capability provider entry, UCS Manager will stop offering that entry as a valid option in new policies even though it may still be referenced by existing ones, which is a common source of 'deprecated capability' warnings during upgrades. A value of 'true' would mean this particular catalog entry has been superseded by a newer one and is kept only for backward compatibility.
