Switch activation and deactivation

High availability considerations
Fabric names locally configured or obtained from a remote switch are saved in the configuration
database, and then synchronized to the standby CP on dual-CP-based systems.
Upgrade and downgrade considerations
Fabric names are lost during a firmware downgrade. No default fabric name is provided. If a fabric
name is needed, it must be configured after the upgrade.
Config file upload and download considerations
A new key, “fabric name” is added to store the user configuration. You can only configure fabric
names using config download when the switch is offline.
Switch activation and deactivation
By default, the switch is enabled after power is applied and diagnostics and switch initialization
routines have finished. You can disable and re-enable the switch as necessary.
Disabling a switch
1. Connect to the switch and log in using an account assigned to the admin role.
2. Enter the switchDisable command.
All Fibre Channel ports on the switch are taken offline. If the switch is part of a fabric, the fabric
is reconfigured.
Enabling a switch
1. Connect to the switch and log in using an account assigned to the admin role.
2. Enter the switchEnable command.
All Fibre Channel ports that passed Power On Self Test (POST) are enabled. If the switch has
inter-switch links (ISLs) to a fabric, it joins the fabric.
Switch and enterprise-class platform shutdown
To avoid corrupting your file system, Brocade recommends that you perform graceful shutdowns of
Brocade switches and enterprise-class platforms.
Warm reboot (also known as graceful shutdown) refers to shutting down the switch or platform by
way of the following instructions. Cold boot (also known as a hard boot) refers to shutting down the
switch or platform by suddenly shutting down power and powering on again.
