number of test count debug events are seen; then the S.M.A.R.T.
debug bit is turned back off. More than the requested count of debug
events may be generated before the software can turn all debug
events off. This option has no effect if S.M.A.R.T. is set to No.
ForceHAWide16 = [Yes | No]
ForceHAWide32 = [Yes | No]
These two options are used to override the information obtained
from the operating system driver about whether or not host
adapters support Wide SCSI. These switches are especially useful
with older drivers that do not report to SCSI whether or not a host
adapter supports Wide SCSI. The default value for both switches is
No, which forces SCSI to rely upon operating system driver
information. If ForceHAWide16 is set to Yes, then all host adapters
are assumed to support at least 16-bit Wide SCSI. If ForceHAWide32
is set to Yes, then all host adapters are assumed to support at least
32-bit Wide SCSI.
If an operating system driver reports that a host adapter supports
32-bit Wide SCSI when ForceHAWide16 is set to Yes, then that host
adapter will still be treated as a 32-bit Wide SCSI device. In other
words, these switches may "widen" a host adapter, but will never
make it "narrower" than what the operating system driver reports.
The switch values are only applied when a host adapter is
discovered; if a host adapter already exists in the device database
then these switches have no effect upon that host adapter or upon
subsequently added devices. Therefore, the device database should
usually be cleared after changing these switches.
Caution:
Use these switches with care! If they are set
!
incorrectly, and the host adapter if forced wider than it
actually is, the system may attempt I/O to a SCSI ID which
cannot exist. The results of doing so are unpredictable.
