The following sequence of commands result in an incorrect failure message being printed: echo 0x7fffffff > /sys/module/qla2xxx/parameters/logging modprobe target_core_mod modprobe tcm_qla2xxx mkdir /sys/kernel/config/target/qla2xxx mkdir /sys/kernel/config/target/qla2xxx/<port-name> mkdir /sys/kernel/config/target/qla2xxx/<port-name>/tpgt_1 echo 1 > /sys/kernel/config/target/qla2xxx/<port-name>/tpgt_1/enable echo 0 > /sys/kernel/config/target/qla2xxx/<port-name>/tpgt_1/enable qla2xxx [0001:00:02.0]-e881:1: qla2x00_wait_for_hba_online() failed The reason of this message is the QLA_FUNCTION_FAILED code that qla2x00_wait_for_hba_online() returns. However, qlt_disable_vha() expects that adapter is offlined and QLA_FUNCTION_FAILED informs about the offline state of the adapter. The qla2x00_abort_isp() function finishes the execution at the point of checking the adapter's mode (for example, qla_tgt_mode_enabled()) because of the qlt_disable_vha() calls qlt_clear_mode() method. It means that qla2x00_abort_isp() keeps vha->flags.online is equal to zero. Finally, qla2x00_wait_for_hba_online() checks the state of this flag and returns QLA_FUNCTION_FAILED error code. This patch changes the failure message which informs about adapter's offline state.

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.
