Configuration Settings
activated when a Discovery phase is active, the Poll phase is delayed
until the Discovery phase completes. System design prevents a
Statistics phase from being active when a Poll phase is activated.
StatisticsInterval = n
This option configures the frequency (in seconds) that the Statistics
phase is run. The default value is
10 (10 seconds). If a Statistics phase
is activated when a Discovery phase is active, the Statistics phase is
delayed until the Discovery phase completes. System design
prevents a Poll phase from being active when a Statistics phase is
activated.
TapeBusyTolerationTime = n
A tape drive may be legitimately busy for extended periods of time
(e.g., during a retension operation). On some operating systems, the
SCSI Manager has no way to tell the difference between a tape drive
device failure and a legitimate temporary unavailability due to the
tape drive being busy. This option configures the time (in seconds)
that a tape drive may be considered legitimately busy. If a tape drive
fails to respond for a period of time longer than the
TapeBusyTolerationTime, then a device failed trap will be generated.
The default value is
180 (3 minutes). Setting this parameter to zero
eliminates special handling for tape drives.
Lun0Required = [Yes | No]
This option tells the SCSI Manager whether LUN 0 must be present
before LUNs other than 0 will be checked. A setting of Yes requires
that LUN 0 be present before non-zero LUNs will be checked. The
default value is
No .
Lun0Only = [Yes | No]
This option tells the SCSI Manager whether or not to check LUNs
other than 0. A setting of Yes disables non-zero LUNs. The default
value is
No .
ErrorInstrumentation = [Yes | No]
This option, if Yes, enables the SCSI Manager to collect error related
instrumentation from instrumentation capable drivers. The default
value is
No . If both this option and the IOInstrumentation option are
