NAME

mly - Mylex AcceleRAID/eXtremeRAID family driver

SYNOPSIS

device pci
device mly
device scbus
device da

DESCRIPTION

The mly driver provides support for Mylex AcceleRAID and eX

tremeRAID-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 de

vices on a virtual SCSI bus. Physical devices which are not claimed by a

logical
device are presented on SCSI channels which match the physi

cal channels
on the controller.

HARDWARE

Controllers supported by the mly driver include:

+o Mylex AcceleRAID 160
+o Mylex AcceleRAID 170
+o Mylex AcceleRAID 352
+o Mylex eXtremeRAID 2000
+o 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. Normal

ly 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 compati

ble (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 con

troller'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.
