Disabling FC Fastwrite on a blade or switch

Disable FC Fastwrite using the fastWriteCfg command. Disabling FC Fastwrite with this command
disrupts data traffic. For the B-Series Multi-Protocol Router Blade, the command powers the blade off and
back on. In the case of the HP StorageWorks 400 Multi-Protocol Router, the router is rebooted. The process
takes up to five minutes.
1. Connect to the switch and log in using an account assigned to the admin role.
2. Enter the following command:
switch:admin> fastwritecfg --disable slot
where slot is the slot in which the B-Series Multi-Protocol Router Blade is installed. A slot number is not
required for the HP StorageWorks 400 Multi-Protocol Router.
