| * scsi: qla2xxx: Log message "skipping scsi_scan_host()" as informationalMauricio Faria de Oliveira2022-09-011-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | Although qla2xxx driver is calling schedule_{,delayed}_work() from 10 locations, I assume that flush_scheduled_work() from qlt_stop_phase1() needs to flush only works scheduled by qlt_sched_sess_work(), for this loop continues while "struct qla_tgt"->sess_works_list is not empty.

| | | | | | | | | | | | | | | | | | | | | | | | | User experience slow recovery when target device went through a stop/start of the authentication application (app_stop/app_start). Between the period of app_stop and app_start on the target device, target device choose to send ELS Reject for any receive AUTH ELS command. At this time, authentication application does not do ELS reject if it encounters error. Therefore, AUTH ELS reject signify authentication application is not running. If driver passes up the AUTH ELS Reject to the authentication application, then it would result in authentication application retrying/resending the same AUTH ELS command again + delay. As a work around, driver should trigger a session tear down where it tells the local authentication application to also tear down. At the next relogin, both sides are then synchronized.
