Mauricio, > This message is helpful to troubleshoot missing LUNs/SAN boot errors. > It'd be nice to log it by default instead of only enabled with debug. Applied to 6.1/scsi-staging, thanks!

This message is helpful to troubleshoot missing LUNs/SAN boot errors. It'd be nice to log it by default instead of only 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. But 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) w/ it there by default. (And it also would help support/triage/deflection tooling.) P.S.: I can't test it on real hardware now (built on next-20220811), but it's just like other messages in the same function, just below.
