If after an adapter reset the appearance of link is not recovered, the devices are not rediscovered. This is result of a race condition between adapter reset (abort_isp) and the topology scan. During adapter reset, the ABORT_ISP_ACTIVE flag is set. Topology scan usually occurred after adapter reset. In this case, the topology scan came earlier than usual where it ran into problem due to ABORT_ISP_ACTIVE flag was still set. kernel: qla2xxx [0000:13:00.0]-1005:1: Cmd 0x6a aborted with timeout since ISP Abort is pending kernel: qla2xxx [0000:13:00.0]-28a0:1: MBX_GET_PORT_NAME failed, No FL Port. kernel: qla2xxx [0000:13:00.0]-286b:1: qla2x00_configure_loop: exiting normally. local port wwpn 51402ec0123d9a80 id 012300) kernel: qla2xxx [0000:13:00.0]-8017:1: ADAPTER RESET SUCCEEDED nexus=1:0:15.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
