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
A-3
