Historymode - Brocade Communications Systems A7533A - Brocade 4Gb SAN Switch Base Command Reference Manual

historyMode

Displays or sets the mode of the field replaceable unit (FRU) history log.
Synopsis historymode [ rot | fi ]
Description Use this command to display or set the mode of the history buffer, which records the insertion and
removal of FRUs on a switch or chassis.
This command supports two modes of handling new log entries once the history buffer has
reached its maximum size:
Rotating mode
First-in mode
The size of the history buffer depends on the HW platform: The Brocade 48000 Director supports
100 history log entries. The Brocade DCX backbone supports a maximum log size of 50 entries.
Since the WWNs are completely separate FRUs in the DCX, they have redundant data in these
units. All other platforms containing FRUs support 28 history log entries.
Operands When invoked without operands the command displays the mode of the history log.
Setting the mode of the history log requires root permission. The following operands are supported
when the command is executed as root:
rot
fi
When setting the history mode, you are prompted to clear the log.
