Quota Management Workflows User Guide

For Use with OnCommand® Workflow Automation

 

Introduction to Quota Management
Quotas provide a way to restrict or track the disk space and number of files used by a user, group, or qtree. You can use quotas to limit resource usage, to provide notification when resource usage reaches specific levels, or to track resource usage.
Quotas can be of different type such as, user, group, or tree. Quota targets specify the user, group, or qtree for which the quota limits are applied.

This workflow when executed allows you to implement the set, resize, and delete quota features for the selected FlexVol or FlexGroup volumes. FlexGroup support is from ONTAP 9.5 onwards. Before executing these features, you can create a new qtree or select an existing qtree on CDOT according to user request. Quota reporting and qtree support for FlexGroups allows you to migrate your workflows to FlexGroups to attain performance and scalability advantages.

Why you should use the Quota Management pack
The Quota management workflow enables you to create tree and user quota types. When you provide the Username parameter, the workflow sets a user quota.
You can use the Quota Management workflow to create quota rules. However, you cannot create quota policies.
You can use this workflow to perform the following actions:

·         Create a new qtree, set and initialize quota

·         Set quotas for existing qtree or user and re-initialize

·         Resize quotas for existing qtree or user

·         Delete quotas

·         Set execution options

 

Prerequisites for executing the workflows

You must ensure that certain requirements are met before executing the Quota Management workflows. You must be a storage architect for executing this workflow.

·         You must have downloaded the Quota Management workflow pack from the Storage Automation Store.
http://automationstore.netapp.com/pack-list.shtml

·         Your system must be running clustered Data ONTAP 8.3.1. and above.

·         You must have installed WFA 3.0.

·         You must have added the OnCommand Unified Manager 6.2 or later as a data source in WFA.

·         You must add your cluster as a data source in your WFA with “Cluster Data ONTAP – Quota-8.3.X” Data Source type.

·         You must have re-set and acquired the scheme before execution.

·         Cluster data source must be acquired when manual acquisition is happened on OCUM.

·         You must have assigned quota policy to Vserver.

Refer to the table in the Workflow in the Quota Management Pack section that specifies the input parameters required for each of the workflow.
Optional: Click Preview to validate your workflow before executing it.

·         Click Execute.

·         You can also schedule the workflow for execution at a later date and time by selecting the Choose Date and Time for Execution check box.

 

Result  

This workflow when executed allows you to implement the set, resize, and delete quota for the selected FlexVol or FlexGroup volumes.
