Chapter 3 Functions of NEC Storage PathManager
(Recovery check is not for Windows Server 2003.)
/2/ Request interval
The path patrol service issues monitoring requests for each path to the NEC Storage PathManager driver
at this interval (default: 60, unit: seconds).
/3/ Threshold
This refers to a period of time in which paths have not been used. Threshold is used to determine if
monitoring I/O should be issued to the designated paths when the NEC Storage PathManager dri ver
receives monitoring requests. Monitoring I/O will be issued if paths have not been used for longer than
this period of time (default: 60, unit: seconds).
(This parameter is not for Windows Server 2003.)
/4/ Timeout duration
This refers to the timeout duration for monitoring I/O. NEC Storage Path Manager will decide that
failures have occurred if monitoring I/O is not complete within the timeout duration (default; 120, unit:
seconds).
(This parameter is not for Windows Server 2003.)
Parameters of arguments specified in the -setwatcher option can be omitted like in the case when
specifying path numbers in the -path option.
