The possible status values for the SAS Fabric Path Data View and the SAS Fabric Path Graphical View are defined in the following table.

Table 1. Possible status values
Status	Description
Operational	No problem detected
Degraded	The SAS node is degraded
Failed	The SAS node is failed
Suspect¹	The SAS node is suspect of contributing to a failure
Missing¹	The SAS node is no longer detected by controller
