Most of the time when we deal with expanding a SAN Fabric, we will be performing switch addition and switch refresh tasks. When we add/introduce new switches to existing SAN fabric, one of the key task is mainly related to settings switch domain ID. We have to make sure that the domain ID is unique and avoiding the possibilities of domain ID conflicts.
Today we will be considering a scenario where we have to change domain ID of a Brocade switch. Once you have powered on the switch, try connecting to the CLI using putty or similar tool
login with "admin" account and run "switchshow" command.
to set the domain ID in a Brocade switch, first you have to disable the switch using "switchdisable" command
you will be prompted with "Fabric parameters" along with possible choices to enter yes or no. The default option is No. if you really want to change the settings, press Y
enter the unique domain ID according to your choice and keep the other values unchanged.
Once you are done with the other variables, exit from the configure option, the switch will prompt you a warning message about the domain ID change.
wait for few minutes and issue "switchshow" command and check the domain ID. you will see new domain ID.
