The following sequence of event leads to NVME port disappearing:
- device port shut
- nvme_fc_unregister_remoteport
- device port online
- remote port delete completes
- relogin is scheduled
- "post gidpn" message appears due to rscn generation # mismatch
In short, if a device comes back online sooner than an unregister
completion, a mismatch in rscn generation number occurs, which is not
handled correctly during device relogin. Fix this by starting with a redo
of GNL.
When ql2xextended_error_logging is enabled, the re-plugged device's
discovery stops with the following messages printed:

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.
