Monitoring VPorts with fc_vport (FC and FCoE Drivers)
For the FC RHEL5.x Driver
In the FC RHEL5.x driver, the fc_vport directory does not exist (yet) so a link from the
physical port to the VPort is present in the fc_host’s device directory.
ls /sys/class/fc_host/host5/device/
fc_host:host5 power scsi_host:host5
host6 uevent
In this example, host6 is a VPort of physical port host5.
To find the VPorts that have been created by a physical port, you can list the fc_host’s
device directory for the physical port. This gives you a link to the fc_host and scsi_host
directory as usual, and it also displays a list of VPorts (in the form of hostx) that were
created on this physical port.
For FC RHEL6.x/SLES11-SPx Drivers
In the FC and FCoE RHEL6.x/SLES11-SPx driver, the transport creates an fc_vports
directory that you can use to monitor VPorts. This directory is populated entirely of
VPorts and has links from each to the fc_host associated with that VPort.
ls /sys/class/fc_vports/
vport-5:0-0
ls -d /sys/bus/pci/drivers/lpfc/*/host*/*/host*
/sys/bus/pci/drivers/lpfc/0000:03:06.1/host5/vport-5:0-0/host6
ls /sys/devices/pci*/*/host5/vport-5*/host6
power rport-6:0-0 rport-6:0-1 rport-6:0-2 uevent
ls /sys/devices/pci*/*/host5/vport-5*/host6/rport-*

vport_delete Write-
only WWPN; WWNN /sys/class/fc_host/hostX/vport_delete
This entry deletes a VPort on the physical port that hostX is
located on. The VPort matching the WWPN and WWNN is
immediately deleted.
This entry returns a “0” if the VPort deletion was successful. A
non-zero value indicates that the VPort was not deleted.
If an fc_host does not support NPIV, then this sysfs entry may
not exist.
Note: This entry deletes the VPort even if there are mounted
file systems being accessed through this VPort, or if
there are open files on it.
