No Negotiation:
noneg Syntax: noneg=
Default value: None
Valid options: 0–15
Function: Specify the target ID of the device that does not accept sync and
wide negotiation.
The noneg option allows you to specify no negotiation for the target ID of a
device. Initially, during the scanning phase, the driver begins by negotiating
with the asynchronous and narrow mode settings with each device found. Once
the system establishes target communication, the desired settings are
renegotiated. However, some devices have a problem with the initial
negotiation, such as the SAF-TE chip from another vendor, and older or
nonstandard, non-INT13h devices.
Parity:
parity
or
ecc Syntax: parity=[targetIDlist]
Default value: on
Valid options: on, off, parity, ecc
Description of each option: parity/error checking is enabled; parity/error
checking is disabled; bus parity is enabled (without error checking); parity/error
checking is enabled.
Function: Controls parity/error checking for the specified target ID(s).
This option allows you to enable/disable the SCSI bus data integrity checking
feature known as parity. Some SCSI devices do not generate parity in which
case this option allows disabling this feature.
Read Capacity:
readcap
or
rc Syntax: readcap=[targetIDlist]
Default value: on
Valid options: on, off
Function: Enables a read capacity command during initial scan to the target
ID(s).
This option allows you to disable issuing the read capacity command during an
initial scan to the target ID(s).
Scan:
scan Syntax: scan=[targetIDlist][lunIDlist]
Default value: list
Valid options: on, off, list, or order
Function: Specify Logical Unit Numbers (LUNs) to scan.
This option allows you to enable the number of LUNs for scanning per the
target ID(s) on the SCSI bus.
