mlx — Mylex DAC-family RAID driver

       The mlx driver was written by Michael Smith <msmith@FreeBSD.org>.

       This manual page was written by Jeroen Ruigrok van der Werven  <asmodai@FreeBSD.org>  and  Michael  Smith
       <msmith@FreeBSD.org>.

       The  DEC  KZPSC  has  insufficient  flash  ROM  to  hold any reasonably recent firmware.  This has caused
       problems for this driver.

       The driver does not yet support the version 6.x firmware as found in the AcceleRAID 352  and  eXtremeRAID
       2000 and 3000 products.

Debian                                          February 15, 2017                                         MLX(4)

       The  mlx  driver  provides  support for Mylex DAC-family PCI to SCSI RAID controllers, including versions
       relabeled by Digital/Compaq.

Controllerinitialisationphasemlx%d:controllerinitialisationinprogress...mlx%d:initialisationcomplete

       Errors occurred preventing one or more system drives from being configured.

       mlx%d:newcontrollerconfigurationfound

       The controller has detected a configuration on disk which supersedes the configuration in its nonvolatile
       memory.  It will reset and come up with the new configuration.

       mlx%d:FATALMEMORYPARITYERROR

       Firmware detected a fatal memory error; the driver will not attempt to attach to this controller.

       mlx%d:unknownfirmwareinitialisationerror%x:%x:%x

       An unknown error occurred during initialisation; it will be ignored.

       A resource allocation error occurred while initialising the driver; initialisation  has  failed  and  the
       driver will not attach to this controller.

       mlx%d:errorfetchingdrivestatus

       The  current  status  of  all  system  drives  could  not be fetched; attachment of system drives will be
       aborted.

       mlx%d:device_add_childfailedmlx%d:bus_generic_attachreturned%d

       Creation of the system drive instances failed; attachment of one or more  system  drives  may  have  been
       aborted.

       mlxd%d:detaching...

       The indicated system drive is being detached.

       mlxd%d:stillopen,can'tdetach

       The indicated system drive is still open or mounted; the controller cannot be detached.

       mlx%d:flushingcache...

       The controller cache is being flushed prior to detach or shutdown.

       An I/O error was reported by the controller.

       mlx%d:periodicenquiryfailed-%s

       An attempt to poll the controller for status failed for the reason given.

       mlx%d:mlx_periodic_enquiry:unknowncommand%x

       The periodic status poll has issued a command which has become corrupted.

       The drive at channel:target has been reset, killed for the given reason, or experienced a SCSI error.

       mlx%d:unknownlogmessagetype%xmlx%d:errorreadingmessagelog-%s

       An error occurred while trying to read the controller's message log.

       mlxd%d:consistencycheckstartedmlx%d:consistencycheckcompleted

       controller.)

       mlx%d:controllerwedged(nottakingcommands)

       The controller is not responding to attempts to submit new commands.

       mlx%d:duplicatedoneeventforslot%dmlx%d:doneeventfornonbusyslot%d

       Corruption has occurred in either the controller's onboard list of commands or in the driver.

       Controllers supported by the mlx driver include:

       •   Mylex DAC960P
       •   Mylex DAC960PD / DEC KZPSC (Fast Wide)
       •   Mylex DAC960PDU
       •   Mylex DAC960PL
       •   Mylex DAC960PJ
       •   Mylex DAC960PG
       •   Mylex DAC960PU / DEC PZPAC (Ultra Wide)
       •   Mylex AcceleRAID 150 (DAC960PRL)
       •   Mylex AcceleRAID 250 (DAC960PTL1)
       •   Mylex eXtremeRAID 1100 (DAC1164P)
       •   RAIDarray 230 controllers, aka the Ultra-SCSI DEC KZPAC-AA (1-ch, 4MB cache), KZPAC-CA  (3-ch,  4MB),
           KZPAC-CB (3-ch, 8MB cache)

       All  major  firmware  revisions  (2.x, 3.x, 4.x and 5.x) are supported, however it is always advisable to
       upgrade to the most recent firmware available for the controller.

       Compatible Mylex controllers not listed should work, but have not been verified.
