30.Dt IPS 4
31.Os
32.Sh NAME
33.Nm ips
34.Nd IBM/Adaptec ServeRAID controller driver
35.Sh SYNOPSIS
36.Cd device scbus
37.Cd device ips
38.Sh DESCRIPTION
39The
40.Nm
41driver claims to support the
42.Tn IBM
43(now Adaptec) ServeRAID series
44.Tn SCSI
45controller cards.
46Some supported devices include:
47.Pp
48.Bl -item -compact
49.It
50IBM ServeRAID 3H
51.It
52ServeRAID 4L/4M/4H
53.It
54ServeRAID Series 5
55.It
56ServeRAID 6i/6M
57.It
58ServeRAID 7t/7k/7M
59.El
60.Pp
61Newer ServeRAID controllers are supported by the
62.Xr aac 4
63driver.
64.Pp
65These cards come with a built in configuration utility stored in
66the firmware known as the
67.Tn ISPR .
68This utility is accessed with the
69.Em CTRL + I
70key combination during the initial card
71.Tn POST .
72.Pp
73It is highly recommended that this utility be used to configure the card
74before attempting to diagnose the below error messages.
75.Pp
76In some cases, the
77.Nm
78driver can have difficulties attaching during
79the system initialization period.
80To avoid these difficulties, set the
81.Dl hw.ips.0.disable
82tunable to
83.Dq 1 .
84This
85.Tn MIB
86prevents the driver from attaching.
87.Pp
88If you see occasional iobuf errors on the console after
89.Xr sync 2
90or
91.Xr fsync 2
92are issued, you can try setting
93.Dl debug.ips.ignore_flush_cmd
94tunable to
95.Dq 1
96and see if that stops it.  You can also use
97.Xr sysctl 1
98command to change this setting after boot.
99.Sh DIAGNOSTICS
100Several error codes may be shown when the card initializes the
101.Tn IBM
102.Tn ISPR
103utility and are independent of
104.Dx .

147.Ss Error messages due to DMA:
148.Bl -diag
149.It can't alloc command dma tag
150.It can't alloc SG dma tag
151.It can't alloc dma tag for statue queue
152.It dmamap failed
153.Pp

155.El
156.Ss Cache, buffer, and command errors:
157.Bl -diag

160.Pp
161The
162.Nm
163driver will return
164.Bq Er ENOMEM
165in such cases.
166.It ERROR: unable to get a command! can't flush cache!

175.Sh COMPATIBILITY
176Unlike many of the other
177.Tn SCSI
178devices in
179.Dx ,
180the
181.Nm
182driver does not use the
183.Xr cam 4
184.Tn SCSI
185subsystem.
