Displays the entire field replaceable unit (FRU) history log.
Synopsis historyshow
Description Use this command to display the entire history log, which records insertion and removal events for
field-replaceable units (FRUs), such as blades, power supplies, fans, and World Wide Name (WWN)
cards. 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 chassis-based platforms: CHASSIS, FAN, POWER SUPPLY, SW BLADE (port
blade), 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 respectively 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 48000 director supports
100 history log entries. The DCX Data Center Backbone Director supports a maximum log size of
50 entries. Since the WWNs are completely separate FRUs in the DCX, they will have redundant
data in these units. All other platforms, which contain FRUs, support 28 history log entries.
The execution of this command is subject to Admin Domain restrictions that may be in place.
Operands none
