Description ( |
| |
"A class derived from CIM_Capabilities that models the " |
| |
"capabilities of a multipath driver. Note that \'path\' in this " |
| |
"context refers to end-to-end device paths (for example, SCSI " |
| |
"initiator/target) with no understanding of edge paths between " |
| |
"interconnect elements such as switches. Load balancing only " |
| |
"applies to symmetric multipath devices or to the ports in " |
| |
"SCSITargetPortGroups in active access state. \n" |
| |
"A driver may support different algorithms for load balancing. " |
| |
"A few common algorithms are listed. Algorithms for specific " |
| |
"device models and software vendor specific algorithms are also " |
| |
"accommodated. \n" |
| |
"\n" |
| |
"An instance of this capabilities class MUST be instantiated " |
| |
"whenever SCSIPathConfigurationService is instantiated and they " |
| |
"MUST be assocaited one to one using ElementCapabilities. " |
| |
"Multiple instances of the service/acapabilities pair MAY exist " |
| |
"if multiple multipath drivers are installed. Each " |
| |
"LogicalDevice subclass served by the underlying multipath " |
| |
"driver is associated to the associated Service instance via " |
| |
"ServiceAvailableToELement." )] |
