Configuring SCSI Flow Identifiers

A SCSI flow identifier is unique on a switch and is chosen by the user, like VSAN identifiers. To
configure a SCSI flow identifier, follow these steps:
Command
Step 1
switch# config t
switch(config)#
Step 2
switch(config)# scsi-flow flow-id 3
initiator-vsan 2 initiator-pwwn
21:00:00:e0:8b:07:5f:aa target-vsan 4
target-pwwn 2a:20:00:05:30:00:77:e0
switch(config)# no scsi-flow flow-id 3
initiator-vsan 2
