MLX(4) BSD Kernel Interfaces Manual MLX(4) NAME mlx -- Mylex DAC-family RAID driver SYNOPSIS device pci device mlx DESCRIPTION The mlx driver provides support for Mylex DAC-family PCI to SCSI RAID controllers, including versions relabeled by Digital/Compaq. Supported controllers include: o DAC960P o DAC960PD o DAC960PDU o DAC960PL o DAC960PJ o DAC960PG o AcceleRAID 150 o AcceleRAID 250 o eXtremeRAID 1100 All major firmware revisions (2.x, 3.x, 4.x and 5.x) are supported, how- ever it is always advisable to upgrade to the most recent firmware avail- able for the controller. Compatible Mylex controllers not listed should work, but have not been verified. DIAGNOSTICS Controller initialisation phase mlx%d: controller initialisation in progress... mlx%d: initialisation complete The controller firmware is performing/has completed initialisation. mlx%d: physical drive %d:%d not responding The drive at channel:target is not responding; it may have failed or been removed. mlx%d: spinning up drives... Drive startup is in progress; this may take several minutes. mlx%d: configuration checksum error The array configuration has become corrupted. mlx%d: mirror race recovery in progress mlx%d: mirror race on a critical system drive mlx%d: mirror race recovery failed These error codes are undocumented. mlx%d: physical drive %d:%d COD mismatch Configuration data on the drive at channel:target does not match the rest of the array. mlx%d: system drive installation aborted Errors occured preventing one or more system drives from being config- ured. mlx%d: new controller configuration found 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: FATAL MEMORY PARITY ERROR Firmware detected a fatal memory error; the driver will not attempt to attach to this controller. mlx%d: unknown firmware initialisation error %x:%x:%x An unknown error occurred during initialisation; it will be ignored. Driver initialisation/shutdown phase: mlx%d: can't allocate scatter/gather DMA tag mlx%d: can't allocate buffer DMA tag mlx%d: can't allocate s/g table mlx%d: can't make initial s/g list mapping mlx%d: can't make permanent s/g list mapping mlx%d: can't allocate interrupt mlx%d: can't set up interrupt A resource allocation error occurred while initialising the driver; ini- tialisation has failed and the driver will not attach to this controller. mlx%d: error fetching drive status The current status of all system drives could not be fetched; attachment of system drives will be aborted. mlx%d: device_add_child failed mlx%d: bus_generic_attach returned %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: still open, can't detach The indicated system drive is still open or mounted; the controller can- not be detached. mlx%d: flushing cache... The controller cache is being flushed prior to detach or shutdown. Operational diagnostics: mlx%d: ENQUIRY failed - %s mlx%d: ENQUIRY2 failed mlx%d: ENQUIRY_OLD failed mlx%d: FLUSH failed - %s mlx%d: CHECK ASYNC failed - %s mlx%d: REBUILD ASYNC failed - %s mlx%d: command failed - %s The controller rejected a command for the reason given. mlx%d: I/O beyond end of unit (%u,%d > %u) mlx%d: I/O error - %s An I/O error was reported by the controller. mlx%d: periodic enquiry failed - %s An attempt to poll the controller for status failed for the reason given. mlx%d: mlx_periodic_enquiry: unknown command %x The periodic status poll has issued a command which has become corrupted. mlxd%d: drive offline mlxd%d: drive online mlxd%d: drive critical The system disk indicated has changed state. mlx%d: physical drive %d:%d reset mlx%d: physical drive %d:%d killed %s mlx%d: physical drive %d:%d error log: sense = %d asc = %x asq = %x mlx%d: info %4D csi %4D The drive at channel:target has been reset, killed for the given reason, or experienced a SCSI error. mlx%d: unknown log message type %x mlx%d: error reading message log - %s An error occurred while trying to read the controller's message log. mlxd%d: consistency check started mlx%d: consistency check completed A user-initiated consistency check has started/completed. mlx%d: drive rebuild started for %d:%d mlx%d: drive rebuild completed A user-initiated physical drive rebuild has started/completed. mlx%d: background check/rebuild operation started mlx%d: background check/rebuild operation completed An automatic system drive consistency check or physical drive rebuild has started/completed. mlx%d: channel %d pausing for %d seconds mlx%d: channel %d resuming mlx%d: pause command failed - %s mlx%d: pause failed for channel %d mlx%d: resume command failed - %s mlx%d: resume failed for channel %d Controller/channel pause operation notification. (Channel pause is not currently supported on any controller.) mlx%d: controller wedged (not taking commands) The controller is not responding to attempts to submit new commands. mlx%d: duplicate done event for slot %d mlx%d: done event for nonbusy slot %d Corruption has occurred in either the controller's onboard list of com- mands or in the driver.

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