Description  Physical memory collection 
ElementName Memory Collection 
CIM_SystemSpecificCollection 
InstanceID HPQ:HP_MemoryCollection:001 
HP_GroupSystemSpecificCollection 
GroupOperationalStatus Enumerator indicating the group operational status of 
the memory collection. The status is determined as 
follows: 
•  If an instance of HP_MemoryRedundancySet 
exists, GroupOperationalStatus[0] is determined 
from the property 
HP_MemoryRedundancySet.RedundancyStatus. 
•  If no instance of HP_MemoryRedundancySet 
exists, GroupOperationalStatus[0] is determined 
by the ‘worst-of’ algorithm for physical memory 
boards and memory modules. 
For details, see the Memory Collection Status. 
GroupStatusDescriptions GroupStatusDescriptions[0] contains descriptive text 
per GroupOperationalStatus[0]: 
•  Memory collection status: OK 
•  Memory collection status: Degraded 
•  Memory collection status: Unknown
