14 Version 1.0.1
This provider will calculate operational status values for each HBA. These status values will be in
accordance with the HP WBEM TC P00113, HP Consolidated Status Profile. This will allow the condition
of the HBA to participate in the Consolidated Status mechanism. The “worst off” status of these instances
will be aggregated and populated in a single instance of HPSCSI_HBAGroupCollection which then gets
collected by the Base Server provider to participate in the overall consolidated status algorithm. The
instances of HPSCSI_HBAComputerSystem will be associated to HPSCSI_HBAGroupCollection via
HPSCSI_HBAGroupCollectionHBAComputerSystem (CIM_MemberOfCollection). The instances of
HPSCSI_HBAGroupCollection will be associated to the singleton instance of HP_ComputerSystem (HP
Base Server Profile) via a subclass of HP_GroupHostedCollection
(HPSCSI_HBAGroupCollectionComputerSystem).
The consolidated status will be defined with three possible states. These three states are defined in
Table 2 along with the algorithms to calculate each possible status.
Table 2 – Consolidated Status Algorithm
Status Reason for Status
Error
If there is a controller failure or
If there is a physical drive failure or
If there is a Storage Enclosure in Critical condition
Degraded
If none Failed conditions are met and
If a physical drive status is not OK or
If a Storage Enclosure status is not OK
OK
If none of the Failed and none of the Degraded
conditions are met

Figure 5 - HP SCSI HBA profile: MNP Data
The SNIA Disk Drive Lite profile has been extended to include an instance of
HPSCSI_MediaAccessStatData. This is associated to the HPSCSI_DiskDrive instance via
CIM_ElementStatisticalData. The HPSCSI_MediaAccessStatData class has been extended form
CIM_MediaAccessStatData to add properties to report the Monitoring and Performance counters for Hard
Drives.
These classes are conditional and shall be present when the HPSCSI_DiskDrive.DriveHasMNPData
property is set to true (See section 7.4.3).
