Just for the record: I would recommend this particular controller as being rock-solid and fast under heavy load.</p> <blockquote><p>mpt2sas0: log_info(0x30030101): originator(IOP), code(0x03), sub_code(0x0101)</p></blockquote> <p>Sadly, there was no useful documentation from LSI and no good hints anywhere else. Also the <a href="https://github.com/baruch/lsi_decode_loginfo" target="_blank">lsi_log_decode</a> i stumbled upon had no clue at all. What led me to the cause of these messages was an <a href="https://bugs.centos.org/view.php?id=2364" target="_blank">old bug report from CentOS</a> which finally mentioned the <em>exact log message</em> i got and pointed me to an issue with <em>calls to non-existent pages</em> from a controller related management software.</p>
