char variable = {1,22};
The first number is 1, which overrides the default variable with the value 22.
Examples:
The following specifies whether the host bus adapter checks parity on incoming
SCSI data:
ad160_parity[SCSI_NAD160]
If the second number is set to 0, parity checking is enabled. If it is set to 1,
parity checking is disabled.
ad160_parity[SCSI_NAD160] = {First number, second
number}
If, in this example, you want the host bus adapter not to check parity on
incoming SCSI data; define parameters as:
ad160_parity[SCSI_NAD160] = {1,0};
Changing the Maximum Number of LUNs Supported
The default setting for maximum number of LUNs supported is
Disable
. To
enable this setting, you may have to use
vi
to edit the
space.c
file located at:
/etc/conf/pack.d/ad160
. Modify the following line so that
lun=1
:
int ad160_scan_lun=0
Enabling Scatter/Gather and Tagged Queuing
The
adl60
driver supports Scatter/Gather and Tagged Queuing; however, the
Sdsk
(SCSI disk module) driver controls whether these features are enabled or
disabled. Look for the
Sdsk
driver controls in the
space. c
file located at:
/etc/conf/pack. d/Sdsk/space.c
