ONTAP 9.14.1 commands

storage aggregate reallocation start

Start reallocate job on aggregate

Availability: This command is available to cluster administrators at the admin privilege level.


Begins a reallocation scan on a specified aggregate.

Before performing a reallocation scan, the reallocation job normally performs a check of the current layout optimization. If the current layout optimization is less than the threshold, then the system does not perform a reallocation on the aggregate.

You can define the reallocation scan job so that it runs at a specific interval, or you can use the storage aggregate reallocation schedule command to schedule reallocation jobs.


-aggregate <aggregate name> - Aggregate Name

Specify this parameter to specify the target aggregate on which to start a reallocation scan.

{ [-i, -interval <text>] - Interval Schedule

Specified the schedule in a single string with four fields:

  • minute is a value from 0 to 59.

  • hour is a value from 0 (midnight) to 23 (11:00 p.m.).

  • day of month is a value from 1 to 31.

If you specify 31 as the value for the day of the month, reallocation scans will not run in any of the months with fewer than 31 days.
  • day of the week is a value from 0 (Sunday) to 6 (Saturday).

Use an asterisk "*" as a wildcard to indicate every value for that field. For example, an * in the day of month field means every day of the month. You cannot use the wildcard in the minute field.

You can enter a number, a range, or a comma-separated list of values for a field.

| [-o, -once <true>] - Once }

Specifies that the job runs once and then is automatically removed from the system when set to true. If you use this command without specifying this parameter, its effective value is false and the reallocation scan runs as scheduled. If you enter this parameter without a value, it is set to true and a reallocation scan runs once.


cluster1::> storage aggregate reallocation start -aggregate aggr0 -interval "0 23 * 6"

Starts a reallocation job on aggregate aggr0 at 11:00 p.m. every Saturday.
