7 Firmware Download MIB

This section covers the implementation details for the Firmware Download
Management Information Bases (FD-MIB) on the QLogic switch.
Firmware Download MIB Definitions
The FD-MIB enables you to download, install, and activate new firmware on
QLogic switches using the Trivial File Transfer Protocol (TFTP). The downloaded
firmware can be activated using a hot reset (non-disruptive) or a hard reset
(disruptive).
A hot reset is a Non-Disruptive Code Load Activation (NDCLA) operation. The
firmware will be activated, the switch will be reset without a Power On Self Test,
and switch traffic will not be disrupted. The switch does not need to be rebooted
after the firmware is activated. During a hot reset operation, fabric services will be
unavailable for a short period (30-75 seconds depending on switch model). To
ensure that the NDCLA operation is successful, verify that all administrative
changes to the fabric (if any) are complete. When you need to do NDCLA/hot
reset to multiple switches, only perform the NDCLA/hot reset on one switch at a
time, and wait 75 seconds before performing the NDCLA/hot reset operation on
the next switch.
A hard reset is a Normal (or regular) reset operation. The firmware will be
activated, the switch will be reset with a Power On Self Test, and switch traffic will
be disrupted. The switch must be rebooted after the firmware is activated.
