candidatesinterval

Edit online

The candidatesinterval option specifies how often the dsmscoutd daemon searches the file systems for migration candidates.

The dsmscoutd daemon scans the file systems and stores the information in a complete file index (CFI), which is used to search for migration candidates.
Tip: When automatic migration is driven by GPFS™ policy, the dsmscoutd daemon is disabled, and the candidatesinterval option has no effect.

Options File

Place this option at the beginning of the dsm.sys file before any server stanzas.

Syntax


1  CANDIDATESINTERVAL scan_interval

Parameters

scan_interval
Specifies the maximum interval of time that elapses between each successive time the dsmscoutd daemon automatically scans for files in the file systems. The range of values is 0 to 9999. The default is 1.

Specify 0 to continuously scan the file systems. When scanning reaches the end of a file system, the dsmscoutd daemon immediately begins scanning again from the beginning of the file system.

Specify 1 to scan the file systems at intervals that depend on the percentage of the file system content that has changed. The dsmscoutd daemon increases the frequency of scanning as the percentage of file system changes increases. The dsmscoutd daemon reduces the frequency of scanning as the percentage of file system changes decreases. This is the default.

Specify a value from 2 to 9999 to define the number of hours between file system scans. After scanning reaches the end of the file system, the dsmscoutd daemon waits the specified number of hours before starting the next scan.
