6 dpt - DPT ServeRAID IV SCSI host bus adapter and RAID adapter driver
7
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.
17
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.
40
41 Supported Settings
42 o I/O Address: Auto
43
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.
