Linux kernel stable tree
eee8bb4a2b
This message is helpful to troubleshoot missing LUNs/SAN boot errors. It'd
be nice to log it by default instead of only being enabled with debug.
This user had an accidental/forgotten file modprobe.d/qla2xxx.conf w/
option qlini_mode=disabled from experiments with FC target mode, and their
boot LUN didn't come up, as it skips SCSI scan, of course.
However, their boot log didn't provide any clues to help understand that.
The issue/message could be figured out w/ ql2xextended_error_logging, but
it would have been simpler (or even deflected/addressed by user) if it had
been there by default. And it also would help support/triage/deflection
tooling.
Expected change:
scsi host15: qla2xxx
+qla2xxx [0000:3b:00.0]-00fb:15: skipping scsi_scan_host() for non-initiator port
qla2xxx [0000:3b:00.0]-00fb:15: QLogic QLE2692 - QLE2692 Dual Port 16Gb FC to PCIe Gen3 x8 Adapter.
According to:
qla2x00_probe_one()
...
ret = scsi_add_host(...);
...
ql_log(ql_log_info, ...
"skipping scsi_scan_host() for non-initiator port\n");
...
ql_log(ql_log_info, ...
"QLogic %s - %s.\n", ha->model_number, ha->model_desc);

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.
