MLY(4) Device Drivers Manual MLY(4)

NAME

mly — Mylex AcceleRAID/eXtremeRAID family driver

SYNOPSIS

To compile this driver into the kernel, place the following lines in your kernel configuration file:

device pci
device scbus
device da
device mly

Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):

mly_load="YES"

DESCRIPTION

The mly driver provides support for Mylex AcceleRAID and eXtremeRAID-family PCI to SCSI RAID controllers with version 6.00 and later firmware.

Logical devices (array drives) attached to the controller are presented to the SCSI subsystem as though they were direct-access devices on a virtual SCSI bus. Physical devices which are not claimed by a logical device are presented on SCSI channels which match the physical channels on the controller.

HARDWARE

Controllers supported by the mly driver include:

  • Mylex AcceleRAID 160
  • Mylex AcceleRAID 170
  • Mylex AcceleRAID 352
  • Mylex eXtremeRAID 2000
  • Mylex eXtremeRAID 3000

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

DIAGNOSTICS

Controller initialisation phase

mly%d: controller initialisation started
mly%d: initialisation complete

The controller firmware has started initialisation. Normally this process is performed by the controller BIOS, but the driver may need to do this in cases where the BIOS has failed, or is not compatible (e.g. on non-x86 systems).

mly%d: drive spinup in progress

Drive startup is in progress; this may take several minutes.

mly%d: mirror race recovery failed, one or more drives offline
mly%d: mirror race recovery in progress
mly%d: mirror race recovery on a critical drive

These error codes are undocumented.

mly%d: FATAL MEMORY PARITY ERROR

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

mly%d: unknown initialisation code %x

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

Driver initialisation/shutdown phase

mly%d: can't enable busmaster feature
mly%d: memory window not available
mly%d: can't allocate register window
mly%d: can't allocate interrupt
mly%d: can't set up interrupt

The system's PCI BIOS has not correctly configured the controller's PCI interface; initialisation has failed and the driver will not attach to this controller.

mly%d: can't allocate parent DMA tag
mly%d: can't allocate buffer DMA tag
mly%d: can't allocate command packet DMA tag
mly%d: can't allocate scatter/gather DMA tag
mly%d: can't allocate s/g table
mly%d: can't allocate memory mailbox DMA tag
mly%d: can't allocate memory mailbox

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

mly%d: BTL rescan result corrupted

The results of a scan for an attached device were corrupted. One or more devices may not be correctly reported.

mly%d: flushing cache...

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