13 .Nd driver for Adaptec I2O based SCSI/ATA host bus adapters
19 driver provides access to disks
20 and disk arrays controlled by I2O based host bus adapters and
21 SmartRAID SCSI RAID adapters through the standard SCSI disk
24 The adapters currently supported include the following RAID adapters:
26 .Bl -tag -width "Adaptec SmartRAID PM1554" -compact
27 .It Adaptec SCSI RAID 2100S
28 .It Adaptec ATA-100 RAID 2400A
29 .It Adaptec SCSI RAID 3200S
30 .It Adaptec SCSI RAID 3400S
31 .It Adaptec SmartRAID PM1554
32 .It Adaptec SmartRAID PM2554
33 .It Adaptec SmartRAID PM2564
34 .It Adaptec SmartRAID PM2664
35 .It Adaptec SmartRAID PM2865
36 .It Adaptec SmartRAID PM3754
37 .It Adaptec SmartRAID PM3755
38 .It Adaptec SmartRAID PM3757
41 Some of the adapters provide 64 bit PCI,
43 ACPI and up to four channels of Ultra 160 SCSI,
44 or two channels of 1GB Fibre.
45 All support RAID-0, RAID-1, RAID-10, RAID-5 and RAID-50 arrays.
46 All SCSI target types are supported.
47 For the ATA based controllers, one IDE drive per channel is supported.
48 Hot-swapping of IDE drives is not supported at this time.
50 The PCI adapters automatically configure
51 using the configuration mechanism of the bus they are on.
53 the IRQ sometimes has to be assigned from a BIOS configuration menu
54 (some BIOS's do this automatically).
56 All host bus adapters must be configured
57 before they can be used with any operating system.
58 Please contact Adaptec directly to obtain the latest information
59 on configuration utilities for the adapters.
60 Currently there are both a GUI Motif based configuration utility
61 and a CLI based configuration utility available from the Adaptec Web site.
62 Note that in the absence of a native
65 of the configuration utilities
66 does not mean one cannot configure the devices via the BIOS
67 based configuration tool Storage Manager on ROM (SMOR).
69 .Bl -tag -width "/dev/asr*" -compact
71 Adaptec SCSI RAID control nodes
74 The ATA based controllers present their devices as SCSI-like devices via CAM.
75 For IDE drives attached to these cards, a subset of standard SCSI commands
76 and mode pages are understood via translation performed in the card's firmware.
83 driver first appeared as the dpti2o driver under BSDi
87 and was ported over to the CAM layer represented in 4.0.
92 driver was kindly donated by Adaptec
