The type of FRU supported depends on the hardware platform. Each history record contains three lines of information. The first line of each record contains the following: Object type On standalone platforms: FAN, POWER SUPPLY, WWN (WWN card), or UNKNOWN. On enterprise-class platforms: FAN, POWER SUPPLY, CORE BLADE (core switch blade), SW BLADE (port blade), AP BLADE (application processor), CP BLADE (control processor), WWN (WWN card), or UNKNOWN. Object number Slot number for blades. Unit number for all other object types. Event type Inserted, Removed, or Invalid Time of the event Format: Day Month dd hh:mm:ss yyyy The second and third lines of a record contain the factory part number and factory serial number, if applicable: Factory Part Number xx-yyyyyyy-zz or Not available Factory Serial Number xxxxxxxxxxxx or Not available The size of the history buffer depends on the HW platform. The Brocade DCX supports a maximum log size of 50 entries. Because the WWNs are completely separate FRUs in the DCX, they have redundant data in these units. All other platforms that contain FRUs support 28 history log entries. The execution of this command is subject to Virtual Fabric or Admin Domain restrictions that may be in place.
