RETURN DATA

83       The default behavior is to display a table with the default attributes
84       listed below; applying options changes the output to a more detailed
85       format. Limited information (noted in the table below) is applicable if
86       the PMem module is not manageable by the software as indicated by the
87       "ManageabilityState" property.
88
89           Note
90           Some data is endian swapped for human readability.
91
92       DimmID
93           (Default) The PMem module identifier.
94
95       Capacity
96           (Default) The usable capacity of the PMem module as reported by the
97           firmware.
98
99       HealthState
100           (Default) Overall PMem module health. One of:
101
102           •   Healthy

105
106           •   Critical: Features or performance are degraded due to failure.
107
108           •   Fatal: Critical internal state failure (DPA Failure, Internal
109               Buffer Failure, AIT Failure, etc.) is non-recoverable and data
110               loss has occurred or is imminent. In this case, the firmware
111               will disable the media and access to user data and operations
112               that require use of the media will fail.
113
114           •   Non-functional: The PMem module is detected and manageable,
115               though some commands and capabilities may be limited. The PMem
116               module has limited communication or another error preventing
117               complete functionality. Common causes include:
118
119               •   DDRT memory interface training failure
120
121               •   Expected region mapping to SPA range unable to be found
122
123           •   Unmanageable: The PMem module has an incompatible firmware API
124               version or hardware revision or is unresponsive (possibly due
125               to a communication interface failure or a firmware/hardware
126               error).
127
128           •   Unknown: Unable to determine the PMem module health state.
129               Refer to HealthStateReason for HealthState details.
130
131       HealthStateReason
132           Indicates why the PMem module is in the current Health State. One
133           or more of:
134
135           •   None
