You use the fcp commands for most of the tasks involved in managing the FCP service and the target and initiator HBAs. For a quick look at all the fcp commands, enter the fcp help command at the storage system prompt.
You can also use FilerView and go to
If FCP service is not running, target HBAs are automatically taken offline. They cannot be brought online until the FCP service is started.
To verify that the FCP service is running, complete the following step.
| 1 |
fcp status ResultA message is displayed indicating whether FCP service is running. Note |
To verify whether the FCP service is licensed, complete the following step.
| 1 |
license ResultA list of all available services appears, and those services that are enabled show the license code; those that are not enabled are indicated as "not licensed." |
To enable the FCP service, complete the following step.
| 1 |
license add license_code license_code is the license code you received when you purchased the FCP license. |
After you license the FCP service on an FAS270 storage system, you must reboot. When the storage system boots up, the port labeled Fibre Channel 2 is in SAN target mode. When you enter Data ONTAP commands that display adapter statistics, this port is slot 0, so the virtual ports are shown as 0c_0, 0c_1, and 0c_2. For detailed information, see Managing the FCP service on systems with onboard ports.
To start and stop the FCP service, complete the following step.
| 1 |
fcp {start|stop}
ExampleResultThe FCP service begins running. If you enter fcp stop, the FCP service stops running. |
To take a target HBAs offline or bring it online, complete the following step.
| 1 |
fcp config adapter [up|down] ExampleResultThe target HBA 4a is offline. If you enter fcp config 4a up, the target HBA is brought online. |
To disable the FCP license, complete the following step.
| 1 |
license delete service service is any service you can license. Example |
The WWNN of a storage system is generated by a serial number in its NVRAM, but it is stored on disk. If you ever replace a storage system chassis and reuse it in the same Fibre Channel SAN, it is possible, although extremely rare, that the WWNN of the replaced storage system is duplicated. In this unlikely event, you can change the WWNN of the storage system.
Caution
If you have a storage system cluster, and the cfmode of each system is single_image, then you must change the WWNN on both systems. If both systems do not have the same WWNN, hosts cannot access LUNs on the cluster.
To change the WWNN, complete the following step.

fcp nodename nodename nodename is a 64-bit WWNN address. Example |
