Mylex Disk Array driver
mdac is the device driver for Mylex Disk Array controllers.
It directly supports these PCI host adapters:
DAC960PTL0 (AcceleRAID 200)
DAC960PTL1 (AcceleRAID 250)
To determine the support status of your host adapter,
contact your system supplier or
refer to the
Compatible Hardware Web Pages.
Configuring the mdac driver
You can configure the mdac driver using entries in
/etc/conf/cf.d/mdevice and /etc/conf/sdevice.d/mdac.
Changes to these files
will only take effect if the kernel is relinked using
and the machine rebooted.
Configure mdac driver-specific characteristics
by editing the /etc/conf/pack.d/mdac/space.c file.
Boot-time configuration of SCSI
parameters to override
the default hardware configuration information.
Of special interest are the adapter= parameter
that specifies information for
the host adapter card
that plugs into or is part of the motherboard,
and the periph= parameter
that specifies information about the host adapter
being used by one of the generic peripheral interfaces
(Sdsk, Srom, or Stp).
The mdac driver
supports all standard SCSI ioctls
that are defined in the <sys/scsicmd.h> header file
and documented on the
for general information about kernel error messages,
including a list of generic device driver errors.
