Attributes in this directory are control interfaces. Attributes: ctlr_create: 'FCoE Controller' instance creation interface. Writing an <ifname> to this file will allocate and populate sysfs with a fcoe_ctlr_device (ctlr_X).

Writing a fcoe_ctlr_device's sysfs name to this file will log the fcoe_ctlr_device out of the fabric or otherwise connected FCoE devices.

Attributes in this directory are control interfaces. Attributes: ctlr_create: 'FCoE Controller' instance creation interface. Writing an <ifname> to this file will allocate and populate sysfs with a fcoe_ctlr_device (ctlr_X). The user can then configure any per-port settings and finally write to the fcoe_ctlr_device's 'start' attribute to begin the kernel's discovery and login process. ctlr_destroy: 'FCoE Controller' instance removal interface. Writing a fcoe_ctlr_device's sysfs name to this file will log the fcoe_ctlr_device out of the fabric or otherwise connected FCoE devices. It will also free all kernel memory allocated for this fcoe_ctlr_device and any structures associated with it, this includes the scsi_host.

The FCoE Controller now has a three stage creation process. 1) Write interface name to ctlr_create 2) Configure the FCoE Controller (ctlr_X) 3) Enable the FCoE Controller to begin discovery and login. The FCoE Controller is destroyed by writing it's name, i.e. ctlr_X to the ctlr_delete file. Attributes: fcf_dev_loss_tmo: Device loss timeout peroid (see below). Changing this value will change the dev_loss_tmo for all FCFs discovered by this controller. mode: Display or change the FCoE Controller's mode. Possible modes are 'Fabric' and 'VN2VN'. If a FCoE Controller is started in 'Fabric' mode then FIP FCF discovery is initiated and ultimately a fabric login is attempted. If a FCoE Controller is started in 'VN2VN' mode then FIP VN2VN discovery and login is performed. A FCoE Controller only supports one mode at a time. enabled: Whether an FCoE controller is enabled or disabled. 0 if disabled, 1 if enabled. Writing either 0 or 1 to this file will enable or disable the FCoE controller. lesb/link_fail: Link Error Status Block (LESB) link failure count. lesb/vlink_fail: Link Error Status Block (LESB) virtual link Loading @@ -26,7 +65,7 @@ Attributes: Notes: ctlr_X (global increment starting at 0) What: /sys/bus/fcoe/fcf_X What: /sys/bus/fcoe/devices/fcf_X Date: March 2012 KernelVersion: TBD Contact: Robert Love <robert.w.love@intel.com>, devel@open-fcoe.org Loading
