https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D271238 --- Comment #12 from Peter Eriksson <pen@lysator.liu.se> --- Correct, it's a workaround. Ideally it would have been constructed as some = kind of blacklist so one could have different override values for different enclosures but that requires more work and this quick fix is good enough. Getting HPE to fix the D6020 enclosures is pretty much impossible I'd say g= iven that it went EOL in 2020 (sure, it theory it's still possible to get service for them since EOSL isn't until 2026). Latest firmware for them was release= d in 2020 (v2.74) - which we run. As long as one limit things to 1-2 enclosures per HBA this problem seems to= be masked and things just "work", it's just when you try to use more that it f= ails (if the enclosure claims too few slots). This makes me think that there sho= uld be a more clear warning/error displayed by the driver when it detects somet= hing like this - since it will be really unobvious for a sysadmin when it happens .-) This (potential) problem isn't just limited to the D6020 enclosures. I did = some quick testing with a few other SAS enclosures f(rom SuperMicro that we use), and they seem to give incorrect values too - however in those cases they cl= aim more slots (43 instead of 24) than they actually have so doesn't trigger th= is problem :-) > # mprutil -u1 show enclosures > Slots Logical ID SEPHandle EncHandle Type > 17 300062b21811f800 0000 0001 Direct Attached SES-2 > 43 50030480216b2c7f 0048 0002 External SES-2 > 43 50030480216b3e7f 0062 0003 External SES-2 --=20 You are receiving this mail because: You are on the CC list for the bug.=
