In a server with an 8G adapter and a 32G adapter, running NVME and FCP, the server would crash with the following stack. RIP: 0010: ... lpfc_nvme_register_port+0x38/0x420 [lpfc] lpfc_nlp_state_cleanup+0x154/0x4f0 [lpfc] lpfc_nlp_set_state+0x9d/0x1a0 [lpfc] lpfc_cmpl_prli_prli_issue+0x35f/0x440 [lpfc] lpfc_disc_state_machine+0x78/0x1c0 [lpfc] lpfc_cmpl_els_prli+0x17c/0x1f0 [lpfc] lpfc_sli_sp_handle_rspiocb+0x39b/0x6b0 [lpfc] lpfc_sli_handle_slow_ring_event_s3+0x134/0x2d0 [lpfc] lpfc_work_done+0x8ac/0x13b0 [lpfc] lpfc_do_work+0xf1/0x1b0 [lpfc] Crash, on the 8G adapter, is due to a vport which does not have a nvme local port structure. It's not supposed to have one. NVME is not supported on the 8G adapter, so the NVME PRLI, which started this flow shouldn't have been sent in the first place. Correct discovery engine to recognize when on an SLI3 rport, which doesn't support SLI3, if the rport supports only NVME, don't send a NVME PRLI. Instead, as no FC4 will be used, a LOGO is sent. If rport is FCP and NVME, only execute the SCSI PRLI.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
