324 Fabric OS Administrator’s Guide

Coordinated Hot Code Load

Coordinated Hot Code Load (HCL) removes the limitations on the number of E_Ports that can be

supported. Fabric OS v6.2.0 and later supports Coordinated HCL on all Fabric OS switches when

connected to a mixed fabric with M-EOS switches running in either McDATA Fabric or McDATA Open

Fabric mode. Coordinated HCL provides:

• Fabric-wide pause and resume

• No limitations on E_Port count or fabric membership

• Flood pause frame to all switches in the fabric before initiating a reboot

Fabric OS running on switches takes approximately 120 seconds to restart as part of the Hot Code

Activation process. During the 120 seconds when the Fabric OS switches are waiting to restart and

the switch service is not available, the M-EOS switches in the fabric may send point-to-point frames

and domain controller frames (GEPT) to the Fabric OS switches. A Fabric OS v6.3.0 switch notifies

all switches in the fabric about a pending Hot Code Activation so that they can stop sending control

frames to the specified switch until it restarts and sends a resume notification. When the switch

initiates a graceful shutdown sequence to prepare for Hot Code load, it sends a Pause notification

frame that support Coordinated HCL switches in the fabric. When the specified switch restarts it

sends out a resume notification.

Bypassing the Coordinated HCL check on firmware download

When you download the Fabric OS firmware on switches in interoperable fabrics, it automatically

starts the Coordinated HCL. The firmwareDownload command checks whether all switches in the

fabric support Coordinated HCL. If Coordinated HCL is supported, the firmwareDownload operation

proceeds and displays the normal message. If Coordinated HCL is not supported, the

firmwareDownload operation fails and prompts you to use the -o option to bypass checking the

Coordinated HCL. All domains are not capable of supporting Coordinated HCL

On switches in interop fabrics, the Coordinated HCL protocol is used to ensure data traffic is not

disrupted during firmware upgrades. Using the firmwareDownload with the -o allows the firmware

download to continue even if Coordinated HCL is not supported in the fabric or the protocol fails.

1. Enter the firmwareDownload command without any option to automatically start Coordinated

HCL.

If Coordinated HCL is not supported, the firmwareDownload operation fails and prompts you to

use the -o option to bypass checking the Coordinated HCL. All domains are not capable of

supporting Coordinated HCL.

Firmwaredownload is not running at that point.

2. Enter firmwareDownload -o to continue the download.

If Coordinated HCL is not supported in the fabric or if there is an Coordinated HCL protocol

failure to one or more of the supported switches, a best effort is made to run the Coordinated

HCL protocol. Traffic disruption can still occur for some switches in the fabric.

The normal firmwaredownload messages are displayed along with the following message:

You have elected to bypass the checking of Coordinated HCL. This may cause

traffic disruption for some switches in the fabric.

Do you want to proceed?
