An issue was seen discovering all SCSI Luns when a target device undergoes link bounce. The driver currently does not qualify the FC4 support on the target. Therefore it will send a SCSI PRLI and an NVMe PRLI. The expectation is that the target will reject the PRLI if it is not supported. If a PRLI times out, the driver will retry. The driver will not proceed with the device until both SCSI and NVMe PRLIs are resolved. In the failure case, the device is FCP only and does not respond to the NVMe PRLI, thus initiating the wait/retry loop in the driver. During that time, a RSCN is received (device bounced) causing the driver to issue a GID_FT. The GID_FT response comes back before the PRLI mess is resolved and it prematurely cancels the PRLI retry logic and leaves the device in a STE_PRLI_ISSUE state. Discovery with the target never completes or resets. Fix by resetting the node state back to STE_NPR_NODE when GID_FT completes, thereby restarting the discovery process for the node.
