historyLastShow

Displays the latest entry in the field replaceable unit (FRU) history log.

Synopsis historylastshow

Description Use this command to display the latest entry of the 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 log 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
