8–Configuring FCoE in a Linux Environment
N_Port ID Virtualization
8-28 FE0254601-00 A
To disable a virtual port, issue the following command, where X is the port SCSI
host ID:
# echo 1 > /sys/class/scsi_host/hostX/vport_disable
To verify that the virtual adapter port has been deleted:
 Confirm that the
sysfs
entry for the virtual port has been removed from
/sys/class/scsi_host/
.
 Confirm that the virtual port is no longer logged into the FCoE switch by
inspecting its Fibre Channel name server database. For information about
examining the name server database, refer to the switch documentation.
Differentiating Virtual Ports from Physical Ports in sysfs
Virtual ports and physical ports have different sets of sysfs parameters. You can
distinguish a virtual port from a physical port by listing the port parameters in
sysfs, and then comparing the display to the unique parameter lists in
Table 8-8 .
Figure 8-11 shows an example the sysfs adapter port parameter lists for a
physical port (left) and a virtual port (right). The distinguishing parameters are
indicated by green and red arrows.
