Modify an efficiency policy

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

Description

The volume efficiency policy modify command can be used to modify the policy attributes.

The attributes of the inline-only predefined policy cannot be modified.

Parameters

-vserver <vserver name> - Vserver
This specifies the Vserver on which the volume is located.
-policy <text> - Efficiency Policy Name
This specifies the policy name.
[-type <Efficiency policy type>] - Policy Type
This specifies the policy type. The policy type defines when the volume using this policy will start processing a changelog. There are two possible values:
  • threshold means changelog processing occurs when the changelog reaches a certain percentage.
  • scheduled means changelog processing will be triggered by time.
The default value is scheduled.
[-schedule <text>] - Job Schedule Name
This specifies the job schedule. Use job schedule show to show all the jobs.
[-duration <text>] - Duration
This specifies the duration that an efficiency operation can run in hours. The possible value is between 1 and 999 inclusive.
[-start-threshold-percent <percent>] - Threshold Percentage
The percentage at which the changelog will be processed. The percentage is checked on an hourly basis. The default value is 20. Valid only if -type parameter is set as threshold.
[-qos-policy <Efficiency QoS policy>] - QoS Policy
This specifies how the efficiency operations are throttled. This option can be configured to be background or best-effort. Default value is best-effort. If background is specified, the efficiency operations are run with minimum or no impact on the data serving client operations. If best-effort is specified, the efficiency operations might have some impact on the data serving client operations.
[-enabled {true|false}] - Enabled
This specifies whether the policy is enabled or not. Default value is true.
[-comment <text>] - Comment
User specified comment.
