fc-port - Oracle® Fabric OS 1.0.2 Command Reference

Language:

`fc-port`

The fc-port command configures and displays the attributes of the FC port. FC storage is supported for the virtualization switch, but not for the leaf switch.

set fc-port {*|slot/port} [–descr=text]
set fc-port {*|slot/port} [–fc-link-down-timeout={number|default}]
set fc-port {*|slot/port} [–fc-target-port-down-timeout={number|default}]
set fc-port {*|slot/port} [–topology={f-port|l-port|n-port}]
show fc-port {*|slot/port} [–detail]
show fc-port {*|slot} alarms [–detail]
show fc-port {*|slot} stats [–detail]
show fc-port {*|slot} vhbas [–detail]
show fc-ports {*|slot/port} [–detail]

Syntax

where slot/port specifies the physical slot and port coordinate to be configured. An asterisk (*) specifies all available FC cards. You can configure FC ports on a virtualization switch, but not on a leaf switch.

These hardware commands have subcommands that determine their functionality. This table describes the subcommands and provides their syntax.

Subcommand	Description
`alarms`	Displays alarms for the specified port.
`stats`	Shows FC port statistics.
`vhbas`	Displays a list of vHBAs connected to the FC port.

Options

Option	Description
`-descr`	Applies a text description to the FC port. Quotes are required around multiple words containing spaces in between.
`-detail`	An optional modifier that displays detailed information (if available) for the FC port.
`-fc-link-down-timeout`	When a fibre link goes down, the FC port waits for the specified number of seconds before declaring the fibre link down. This parameter value in seconds determines the duration for which a link can experience a loss of signal, or be non-operational before the firmware declares the link is down and sends a link down event. This parameter guards against link flapping and excessive reporting of link state changes when there is a constant change in the state of the link. Specify the number of seconds between 0 and 60, or do not specify any value to use the default time-out of 30 seconds.
`-fc-target-port-down-timeout`	When an FC port goes down on a target, the fabric waits for the specified of seconds before declaring the port down. This parameter is a counter that determines the maximum number of seconds a port can remain offline. If the specified number of seconds is exceeded, the port is timed out and declared down. Specify the time-out value as the number of seconds between 0 and 60, or do not specify any value to use the default retry limit. The default limit is 30 seconds.
`-topology`	Specifies the type of storage connection to use: `f-port` – Specifies a point-to-point connection to the storage device through an FC switch. This type of connection supports NPIV. This is the default configuration for an FC module. `l-port` – Specifies a loop connection to the storage device without using an FC switch. This type of connection does not support NPIV. A port configured this way can only support a single vHBA. `n-port` – Specifies a point-to-point connection to the storage device without using an FC switch. This type of connection supports NPIV.

Example: Set the Link Down Timeout

This example shows how to set the FC port wait time to 45 seconds. The port will wait this length of time before declaring that the fibre link is down. The default timeout is 30 seconds.

Note - Modified settings do not become effective until you reset the I/O card. To adopt new settings, the card must be brought down, rebooted, and reinitialized using the set iocard command. For more information, see iocard.

Typically, you should use the default values for FC port parameters, and change them only if absolutely necessary.
