NAME
dpt - DPT ServeRAID IV SCSI host bus adapter and RAID
adapter driver
DESCRIPTION
The dpt driver is a driver for the DPT (Distributed Process-
ing Technology) family of SmartRAID IV SCSI HBA and RAID
adapters. The following HBA adapters are supported: PM2024,
PM2044UW, PM2044W, PM2124, PM2124W, PM2144UW, and PM2144W.
The following RAID adapters are supported: PM3224, PM3224W,
PM3334UW, and PM3334W.
PRECONFIGURATION
o DPT PM3224 only: Only EPROM 7A and later versions are
supported.
o DPT PM2024 and PM2124 only: Only EPROM 6D4 and later
versions are supported.
o Use adapters with SmartROM version 3.B or later ver-
sions only.
o Be sure that the controller board is installed in a
PCI bus-mastering slot.
o Disable PCI parity checking if your firmware version
is earlier than version 7A, if your system memory is
ECC, or if your system does not check parity.
Known Problems and Limitations
During system boot, a message may be displayed saying a DPT
controller driver cannot be installed. This message indi-
cates that the motherboard installed in your system may con-
tain ECC memory or may not check parity. If you see this
message is displayed, disable PCI parity checking.
Supported Settings
o I/O Address: Auto
CONFIGURATION
Auto-configuration code determines whether the adapter is
present at the configured address and what types of devices
are attached to it. The DPT ServeRAID is primarily used as a
disk array (system drive) controller.
To configure the attached disk arrays, you must configure
the controller (using the configuration utilities provided
by the hardware manufacturer) before you boot the Solaris
operating environment. You use the configuration utilities
to set RAID levels, stripe parameters, cache mechanisms and
perform other functions. For more information, see the user
manual supplied with your hardware.
