Command Line Options =======================
.. Warning::
ALTERING OR ADDING THESE DRIVER PARAMETERS
INCORRECTLY CAN RENDER YOUR SYSTEM INOPERABLE.
USE THEM WITH CAUTION.
Put a .conf file in the /etc/modprobe.d directory and add/edit a
line containing options aic7xxx aic7xxx=[command[,command...]] where
command is one or more of the following:
verbose
:Definition: enable additional informative messages during driver operation.
:Possible Values: This option is a flag
:Default Value: disabled
debug:[value]
:Definition: Enables various levels of debugging information
:Possible Values: 0x0000 = no debugging, 0xffff = full debugging
:Default Value: 0x0000
no_probe
probe_eisa_vl
:Definition: Do not probe for EISA/VLB controllers.
This is a toggle. If the driver is compiled
to not probe EISA/VLB controllers by default,
specifying "no_probe" will enable this probing.
If the driver is compiled to probe EISA/VLB
controllers by default, specifying "no_probe"
will disable this probing.
:Possible Values: This option is a toggle
:Default Value: EISA/VLB probing is disabled by default.
pci_parity
:Definition: Toggles the detection of PCI parity errors.
On many motherboards with VIA chipsets,
PCI parity is not generated correctly on the
PCI bus. It is impossible for the hardware to
differentiate between these "spurious" parity
errors and real parity errors. The symptom of
this problem is a stream of the message::
"scsi0: Data Parity Error Detected during address or write data phase"
output by the driver.
:Possible Values: This option is a toggle
:Default Value: PCI Parity Error reporting is disabled
no_reset
:Definition: Do not reset the bus during the initial probe
phase
:Possible Values: This option is a flag
:Default Value: disabled
extended
:Definition: Force extended translation on the controller
:Possible Values: This option is a flag
:Default Value: disabled
periodic_otag
:Definition: Send an ordered tag periodically to prevent
tag starvation. Needed for some older devices
:Possible Values: This option is a flag
:Default Value: disabled
reverse_scan
:Definition: Probe the scsi bus in reverse order, starting
with target 15
:Possible Values: This option is a flag
:Default Value: disabled
global_tag_depth:[value]
:Definition: Global tag depth for all targets on all busses.
This option sets the default tag depth which
may be selectively overridden vi the tag_info
option.
:Possible Values: 1 - 253
:Default Value: 32
tag_info:{{value[,value...]}[,{value[,value...]}...]}
:Definition: Set the per-target tagged queue depth on a
per controller basis. Both controllers and targets
may be omitted indicating that they should retain
the default tag depth.
:Possible Values: 1 - 253
:Default Value: 32
Examples:
::
tag_info:{{16,32,32,64,8,8,,32,32,32,32,32,32,32,32,32}
On Controller 0:
- specifies a tag depth of 16 for target 0
- specifies a tag depth of 64 for target 3
- specifies a tag depth of 8 for targets 4 and 5
- leaves target 6 at the default
- specifies a tag depth of 32 for targets 1,2,7-15
- All other targets retain the default depth.
::
tag_info:{{},{32,,32}}
On Controller 1:
- specifies a tag depth of 32 for targets 0 and 2
- All other targets retain the default depth.
seltime:[value]
:Definition: Specifies the selection timeout value
:Possible Values: 0 = 256ms, 1 = 128ms, 2 = 64ms, 3 = 32ms
:Default Value: 0
dv: {value[,value...]}
:Definition: Set Domain Validation Policy on a per-controller basis.
Controllers may be omitted indicating that
they should retain the default read streaming setting.
:Possible Values:
==== ===============================
< 0 Use setting from serial EEPROM.
0 Disable DV
> 0 Enable DV
==== ===============================
:Default Value: SCSI-Select setting on controllers with a SCSI Select
option for DV. Otherwise, on for controllers supporting
U160 speeds and off for all other controller types.
Example:
::
dv:{-1,0,,1,1,0}
- On Controller 0 leave DV at its default setting.
- On Controller 1 disable DV.
- Skip configuration on Controller 2.
- On Controllers 3 and 4 enable DV.
- On Controller 5 disable DV.
Example::
options aic7xxx aic7xxx=verbose,no_probe,tag_info:{{},{,,10}},seltime:1
enables verbose logging, Disable EISA/VLB probing, and set tag depth on Controller 1/Target 2 to 10 tags.
