The default handling of the NOT READY sense key is to wait for the device
to become ready. The "wait" is assumed to be relatively short. However
there is a sub-class of NOT READY that have the "... in progress" phrase in
their additional sense code and these can take much longer. Following on
from commit 505aa4b6a8 ("scsi: sd: Defer spinning up drive while SANITIZE
is in progress") we now have element depopulation and restoration that can
take a long time. For example, over 24 hours for a 20 TB, 7200 rpm hard
disk to depopulate 1 of its 20 elements.
Add handling of ASC/ASCQ: 0x4,0x24 (depopulation in progress)
and ASC/ASCQ: 0x4,0x25 (depopulation restoration in progress)
to sd.c . The scsi_lib.c has incomplete handling of these
two messages, so complete it.

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.
