Disabling FC Fastwrite for a blade or switch
Disable FC Fastwrite using the fastwritecfg command. Disabling FC Fastwrite with this command
disrupts data traffic. For the FR4-18i blade, the command powers the blade off and back on. In the case of
the 400 MP Router, the switch is rebooted. The process takes up to five minutes.
#fastwritecfg —disable <slot#>
Where <slot#> is the slot in which the FR4-18i blade is installed. A slot number is not required for the 400
MP Router.
