If the softreset fails in the I_T reset, libsas will then continue to issue a controller reset to try to recover. However a faulty disk may cause the softreset to fail, and resetting the controller will not help this scenario. Indeed, we will just continue the cycle of error handle handling to try to recover. So if the softreset fails upon certain conditions, just disable the phy associated with the disk. The user needs to handle this problem.

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.
