Take the following steps to configure and enable FC Fastwrite. 1. Create a zone configuration to filter FC Fastwrite flows. FC Fastwrite flows are configured by creating a zone name with an fcacc token as a prefix. For LSAN configuration, use lsan_fcacc as a prefix, as shown in the following example. switch:admin> zonecreate fcacc_myzone1, "initiator-wwn; target-wwn" switch:admin> zonecreate LSAN_fcacc_myzone2, "initiator-wwn; target1-wwn; target2-wwn" switch:admin> cfgcreate mycfg, "fcacc_myzone1; LSAN_fcacc_myzone2" switch:admin> cfgenable mycfg 2. Enable FC Fastwrite using the fastWriteCfg command. Enabling or 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. Example: Enabling Fastwrite on a switch switch:admin> fastwritecfg --enable slot where slot is the slot number 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. switch:admin> fastwritecfg --enable 7 !!!! WARNING !!!! Enabling FC Fastwrite will require powering off and back on the and it may take up to 5 minutes. For non bladed system, the switch will be rebooted. Data traffic will be disrupted. Continue (Y,y,N,n): [ n] y 3. Enable FC Fastwrite on the ports using the portCfg command. switch:admin> portcfg fastwrite [slot/]port --enable where slot is the slot in which the B-Series Multi-Protocol Router Blade is installed and port identifies the port number you want to enable. A slot number is not required for the BHP StorageWorks 400 Multi-Protocol Router. 4. Repeat step 1 through step 3 for the blade or router on the other end of the FC Fastwrite path. 472 Configuring and monitoring FCIP extension services
