Table 110 Hot Code upgrade considerations Fabric OS Versions Notes Upgrading from any other down-level • Must upgrade to Brocade Native release mode, and then change the interopmode; cannot be in McDATA Open Fabric mode before the upgrade. • The upgrade is disruptive or has the potential to be disruptive.

Firmwaredownload checks whether all switches in the fabric support HCL. If HCL is supported, firmwaredownload proceeds and displays the normal message. If HCL is not supported, firmwaredownload fails and prompts you to use the -o option. Firmwaredownload is not running at that point. 2. Enter firmwaredownload -o. Firmwaredownload does not check whether all switches in the fabric support HCL. If the normal checks are successful, it proceeds and displays the normal message plus an additional message. The firmwaredownload -o command upgrades both CPs in the switch. If you want to upgrade a single CP only, use the -s option. You can run firmwaredownloadstatus to get the status of this firmwaredownload. The firmwaredownload -o command causes a warm and nondisruptive boot on the active CP, but requires that existing Telnet, Secure Telnet, or SSH sessions be restarted. 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? If you select yes, firmwaredownload proceeds and failure of the pause protocol is ignored. 494 Implementing an interoperable fabric
