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
