|
|
.Sh SYNOPSIS
|
|
.Cd "mly* at pci? dev ? function ?"
|
|
.Cd "scsibus* at mly?"
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver provides support for Mylex AcceleRAID and eXtremeRAID family
|
|
of PCI to SCSI RAID controllers with version 6.00 and later
|
|
firmware.
|
|
Supported controllers include:
|
|
.Pp
|
|
.Bl -bullet -compact
|
|
.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
|
|
tested.
|
|
.Pp
|
|
Logical devices (disk arrays) 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.
|
|
.Pp
|
|
The results of the SCSI ``INQUIRY'' command from logical devices are
|
|
overwritten with status information by the
|
|
.Nm
|
|
driver. The vendor field is the string ``MYLEX'', the product field
|
|
indicates the type of logical device, and the revision field contains a four
|
|
letter status code. The possible status codes and their meanings are as
|
|
follows:
|
|
.Pp
|
|
.Bl -tag -width XXXX -compact
|
|
.It OFLN
|
|
offline
|
|
.It UNCF
|
|
unconfigured
|
|
.It ONLN
|
|
online - optimal
|
|
.It CRIT
|
|
critical - one or more disks in the array has failed
|
|
.It NORD
|
|
write only
|
|
.It STBY
|
|
standby
|
|
.It MISS
|
|

|
|
.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.
