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);

Overview
This is the source code repository of the SCST project. SCST is a collection of Linux kernel drivers that implement SCSI target functionality. The SCST project includes:
- The SCST core in the scst/ subdirectory.
- A tool for loading, saving and modifying the SCST configuration in directory scstadmin/.
- Several SCSI target drivers in the directories iscsi-scst/, qla2x00t/, srpt/, scst_local/ and fcst/.
- User space programs in the usr/ subdirectory, e.g. fileio_tgt.
- Various documentation in the doc/ subdirectory.
Instructions for building and installing SCST are available in the INSTALL.md file.
QLogic target driver
Two QLogic target drivers are included in the SCST project.
The default driver is located in qla2x00t-32gbit directory and it supports up to 32 Gb/s FC. It is the newer one.
May anyone wish to switch back to the older driver that only supported up to
16 Gb/s adapters, it is located in qla2x00t directory. To make use of the
older driver build scst with environment variable QLA_32GBIT=no set.
