PRIMARYSPMGMTCYCLE: Specifying the cycle for automatic primary space management

Explanation: PRIMARYSPMGMTCYCLE is an optional parameter specifying the days in a cycle when automatic primary space management runs.

PRIMARYSPMGMTCYCLE(cycle): For cycle, substitute a string of alphabetic Ys and Ns. Each Y represents a day in the cycle when automatic primary space management is to run. Each N represents a day in the cycle when automatic primary space management is not to run. You can represent up to 31 days with the Ys and Ns. The current day is the first day of the cycle, unless you specify the cycle start date.

CYCLESTARTDATE can be used with this parameter and is covered separately under CYCLESTARTDATE: Specifying the start date of a cycle.

Defaults: If you do not specify PRIMARYSPMGMTCYCLE or if you specify PRIMARYSPMGMTCYCLE without specifying cycle, automatic primary space management will default to a one-day cycle. Therefore, if a start time has been specified by a SETSYS PRIMARYSPMGMTSTART or AUTOMIGRATIONSTART command, automatic primary space management functions run every day.

If you do not specify both cycle and CYCLESTARTDATE, DFSMShsm will set the cycle to a one-day cycle. Therefore, if a start time has been specified by a SETSYS PRIMARYSPMGMTSTART or AUTOMIGRATIONSTART command, automatic primary space management functions will run every day.

Note:

If you specify CYCLESTARTDATE, you must also specify cycle; otherwise, the DEFINE PRIMARYSPMGMTCYCLE command will fail.
The first day of the cycle is DAY 1. The second day in the cycle is DAY 1 until the start time for the function is reached; then it becomes DAY 2. Third and subsequent days follow the same pattern.
