NAME

6       dpt - DPT ServeRAID IV SCSI host bus adapter and RAID adapter driver
7

DESCRIPTION

9       The dpt driver is a driver for the DPT (Distributed Processing Technol‐
10       ogy) family of SmartRAID IV SCSI HBA and RAID adapters.  The  following
11       HBA adapters are supported: PM2024, PM2044UW, PM2044W, PM2124, PM2124W,
12       PM2144UW, and PM2144W.
13
14
15       The following RAID adapters are supported: PM3224,  PM3224W,  PM3334UW,
16       and PM3334W.

PRECONFIGURATION

19           o      DPT  PM3224  only: Only EPROM 7A and later versions are sup‐
20                  ported.
21
22           o      DPT PM2024 and PM2124 only: Only EPROM 6D4  and  later  ver‐
23                  sions are supported.
24
25           o      Use  adapters  with  SmartROM  version 3.B or later versions
26                  only.
27
28           o      Be sure that the controller board is installed in a PCI bus-
29                  mastering slot.
30
31           o      Disable PCI parity checking if your firmware version is ear‐
32                  lier than version 7A, if your system memory is  ECC,  or  if
33                  your system does not check parity.
34
35   Known Problems and Limitations
36       During  system boot, a message may be displayed saying a DPT controller
37       driver cannot be installed. This message indicates that the motherboard
38       installed  in  your system may contain ECC memory or may not check par‐
39       ity. If you see this message is displayed, disable PCI parity checking.

CONFIGURATION

45       Auto-configuration code determines whether the adapter  is  present  at
46       the  configured  address  and what types of devices are attached to it.
47       The DPT ServeRAID is primarily used as a disk array (system drive) con‐
48       troller.
49
50
51       To  configure  the  attached  disk  arrays, you must configure the con‐
52       troller (using the configuration utilities  provided  by  the  hardware
53       manufacturer)  before  you  boot the Solaris operating environment. You
54       use the configuration utilities to set RAID levels, stripe  parameters,
55       cache mechanisms and perform other functions. For more information, see
56       the user manual supplied with your hardware.
