An intermittent Fabric Login (FLOGI) issue will cause the Port Login (PLOGI) to a Target Port Destination Identifier (D_ID) to timeout due to a routing issue on the Brocade Fibre Channel Switch. The routing issue will manifest itself on a Solaris host by PLOGI to D_ID failed due to timeout events. For example:
- FLOGI request from the host is indicated by cmd 116 with arg 22 to well known address fffffe.
- FLOGI response is indicated by cmd 116 with arg 23 followed by the assigned address.
Introduction of Brocade ClearLink and Marvell StorFusion Diagnostic Port (D_Port) Test with Marvell QLogic 16Gb and 32Gb Fibre Channel Adapters. The D_Port test allows a SAN administrator to quickly verify and validate all physical connections between hosts and switches, including cabling, SFPs, and latency. The D_Port integrated test uses both Brocade ClearLink and Marvell StorFusion technology. When enabled, the D_Port feature tests and measures electrical and optical loopback, link traffic, round-trip link latency, and the estimated cable distance and buffers required.
