1. A method comprising:
- determining, by a target device in a Storage Area Network (SAN), that a first principal member port of a target driven peer zone on the target device is likely to fail based on diagnostic information related to the first principal member port, wherein the target driven peer zone is configured in the SAN via the target device, and wherein the diagnostic information based on which the target device determines that the first principal member port is likely to fail comprises a parameter of a transceiver for the first principal member port;
in response to the determining, identifying, by the target device, an alternate principal member port on the target device; and
providing, by the target device, an indication comprising an identifier of the first principal member port and an identifier of the alternate principal member port, the indication to cause replacement of the first principal member port with the alternate principal member port as a principal member port in the target driven peer zone.

Abstract
Examples disclosed herein relate to identification of an alternate principal member port by a target device in a Storage Area Network (SAN). In some examples, a target device in a SAN may determine that a principal member port of a target driven peer zone on the target device is likely to fail based on diagnostic information related to the principal member port. The target driven peer zone may be configured in the SAN via the target device. In response to determining, the target device may identify an alternate principal member port on the target device. The target device may perform an action to indicate the alternate principal member port as the principal member port.

7. A target device comprising:
-
a processor; and a non-transitory storage medium comprising instructions executable on the processor to; determine in a Storage Area Network (SAN) that a first principal member port of a target driven peer zone on the target device is likely to fail based on diagnostic information related to the first principal member port, wherein the target driven peer zone is configured in the SAN via the target device, and wherein the diagnostic information based on which the target device determines that the first principal member port is likely to fail comprises a parameter of a transceiver for the first principal member port; identify, in response to the determination, an alternate principal member port on the target device; send a request to a network switch in the SAN to replace the first principal member port of the target driven peer zone with the alternate principal member port, the request comprising an identifier of the first principal member port and an identifier of the alternate principal member port; and determine that the request has been completed. - View Dependent Claims (8, 9, 10, 11, 12)

13. A non-transitory machine-readable storage medium comprising instructions that upon execution cause a target device to:
-
determine in a Storage Area Network (SAN) that a first principal member port of a target driven peer zone on the target device is likely to fail based on diagnostic information related to the first principal member port, wherein the target driven peer zone is configured in the SAN via the target device, and wherein the diagnostic information based on which the target device determines that the first principal member port is likely to fail comprises a parameter of a transceiver for the first principal member port; identify an alternate principal member port on the target device, in response to the determination; and send an indication comprising an identifier of the first principal member port and an identifier of the alternate principal member port, the indication to cause replacement of the first principal member port with the alternate principal member port as a principal member port in the target driven peer zone. - View Dependent Claims (14, 15, 16, 17)
