|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver provides support for Mylex AcceleRAID and eXtremeRAID-family
|
|
PCI to SCSI RAID controllers with version 6.00 and later
|
|
firmware.
|
|
Supported controllers include:
|
|
.Bl -bullet
|
|
.It
|
|
AcceleRAID 160
|
|
.It
|
|
AcceleRAID 170
|
|
.It
|
|
AcceleRAID 352
|
|
.It
|
|
eXtremeRAID 2000
|
|
.It
|
|
eXtremeRAID 3000
|
|
.El
|
|
.Pp
|
|
Compatible Mylex controllers not listed should work, but have not been
|
|
verified.
|
|
.Pp
|
|
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.
|
|
.Sh DIAGNOSTICS
|
|
.Ss Controller initialisation phase
|
|
.Bl -diag
|
|
.It "mly%d: controller initialisation started"
|
|
.It "mly%d: initialisation complete"
|
|
.Pp
|
|
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).
|
|
.It "mly%d: drive spinup in progress"
|
|
.Pp
|
|
Drive startup is in progress; this may take several minutes.
|
|
.It "mly%d: mirror race recovery failed, one or more drives offline"
|
|
.It "mly%d: mirror race recovery in progress"
|
|
.It "mly%d: mirror race recovery on a critical drive"
|
|
.Pp
|
|
These error codes are undocumented.
|
|
.It "mly%d: FATAL MEMORY PARITY ERROR"
|
|
.Pp
|
|
Firmware detected a fatal memory error; the driver will not attempt to
|
|
attach to this controller.
|
|
.It "mly%d: unknown initialisation code %x"
|
|
.Pp
|
|
An unknown error occurred during initialisation; it will be ignored.
|
|
.El
|
|
.Ss Driver initialisation/shutdown phase
|
|
.Bl -diag
|
|
.It "mly%d: can't enable busmaster feature"
|
|
.It "mly%d: memory window not available"
|
|
.It "mly%d: can't allocate register window"
|
|
.It "mly%d: can't allocate interrupt"
|
|
.It "mly%d: can't set up interrupt"
|
|
.Pp
|
|
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.
|
|
.It "mly%d: can't allocate parent DMA tag"
|
|
.It "mly%d: can't allocate buffer DMA tag"
|
|
.It "mly%d: can't allocate command packet DMA tag"
|
|
.It "mly%d: can't allocate scatter/gather DMA tag"
|
|
.It "mly%d: can't allocate s/g table"
|
|
.It "mly%d: can't allocate memory mailbox DMA tag"
|
|
.It "mly%d: can't allocate memory mailbox"
|
|
.Pp
|
|
A resource allocation error occurred while initialising the driver;
|
|
initialisation has failed and the driver will not attach to this
|
|
controller.
|
|
.It "mly%d: BTL rescan result corrupted"
|
|
.Pp
|
|
The results of a scan for an attached device were corrupted.
|
|
One or more devices may not be correctly reported.
|
|
.It "mly%d: flushing cache..."
|
|
.Pp
|
|
The controller cache is being flushed prior to detach or shutdown.
