Configuring And Enabling Fc Fastwrite - HP A7533A - Brocade 4Gb SAN Switch Base Administrator's Manual

Configuring and enabling FC fastwrite

The FC-FC (Fibre Channel) Routing Service provides Fibre Channel routing between two or more fabrics
without merging those fabrics. The FC-FC Routing Service can be simultaneously used as a Fibre Channel
router and for SAN extension over wide area networks (WANs) using FCIP.
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..
#zonecreate fcacc_myzone1, "initiator-wwn; target-wwn"
#zonecreate LSAN_fcacc_myzone2, "initiator-wwn; target1-wwn;
target2-wwn"
#cfgcreate mycfg, "fcacc_myzone1; LSAN_fcacc_myzone2"
#cfgenable mycfg
Enable FC fastwrite using the fastwritecfg command. Enabling or disabling FC fastwrite with this
2.
command disrupts data traffic. For the FR4- 1 8i blade, the command powers the blade off and back on.
In the case of the 400 Multi-protocol Router, the switch is rebooted. The process takes up to five
minutes.
#fastwritecfg —enable slot#
Where: slot# is the slot in which the FR4- 1 8i blade is installed. A slot number is not required for the 400
Multi-protocol Router.
Example:
SJ3_6A1_12000_0:root> fastwritecfg --enable 7
!!!! WARNING !!!!
Enabling FC Fastwrite will require powering off and back on the
and it may take upto 5 minutes. For non bladed system, the switch
will be rebooted. Data traffic will be disrupted.
Continue
SJ3_6A1_12000_0:root> fastwritecfg --disable 7
!!!! WARNING !!!!
Disabling FC Fastwrite will require powering off and back on the
and it may take upto 5 minutes. For non bladed system, the switch
will be rebooted. Data traffic will be disrupted.
Continue
Slot 7 is being powered off
3. Enable FC fastwrite on the ports using the portcfg command.
#portcfg fastwrite slot#/port_id —enable
Where slot# is the slot in which the FR4- 1 8i is installed. A slot number is not required for the 400
Multi-protocol Router.
