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 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.
Notes The execution of this command is subject to Virtual Fabric restrictions that may be in place. Refer to "Using Fabric
OS Commands" and "Command Availability" for details.
