Sample workflow requirements checklist


A workflow requirements checklist includes detailed requirements—​such as commands, user input, and resources—​for a planned workflow. You can use the checklist to plan your workflows and identify the gaps in the requirements.

Requirements checklist example

The following sample workflow requirements checklist lists the requirements for the “Create a Clustered Data ONTAP Volume” workflow. You can use this sample checklist as a template to list your workflow requirements.

Workflow details

Requirement Description

Workflow name

Create a Clustered Data ONTAP Volume


Storage provisioning


The workflow creates a new volume in a specific SVM. This workflow is meant for a scenario where a volume is provisioned and delegated for later usage.

High-level description of how the workflow works

  • The SVM that contains the volume is specified by the user (cluster, SVM names).

  • A volume is created based on the specified size.

  • The configuration of the volume is described in a template.


  • Use the Create CM Volume command

  • Command details for Create CM Volume:

    • Execution is set as always

    • Volume details are specified by filling in attributes for the volume

    • Use the Space Guaranteed Settings template for configuring the volume

    • Volume name and size are provided by user.

The volume will be mounted in the SVM namespace as /volname (under the root namespace).

  • Use the actualVolumeSize function because the snap reserve will be 5%.

  • SVM reference is defined with the following resource selection logic:

    • CM SVM by key — searches for SVM by name and the cluster, which is provided by the user

    • CM SVM by type — only data SVMs (type = cluster)

    • SVM by state — (state = running)

  • Aggregate reference is defined with the resource selection logic as a predefined finder (CM Aggregate by space thresholds and RAID Type):

    • CM Aggregate by available capacity (capacity = size of volume to be provisioned, cluster given by user)

    • CM Aggregate by delegation to SVM

    • CM Aggregate by RAID Type (RAID-DP)

    • CM Aggregate not aggr0

    • CM Aggregate by used size % (threshold = 90, spaceToBeProvisioned = size provided, since guarantee is volume)

    • CM Aggregate by over commitment (threshold = 300, spaceToBeAllocated = Size of volume being provisioned)

    • Select the aggregate with maximum free space

User inputs

Name Type Description (data values, validation, and so on)


Locked query (tabular)

  • Cluster hosting the SVM

  • Query can be tabular display with primary address and name of the cluster

  • Sort alphabetically by name


Locked query

  • SVM in which the volume is provisioned

  • Query should only display SVM names belonging to the cluster chosen in the previous input

    Show only cluster type SVMs, not admin or node (type column of cm_storage.vserver)

  • Sort alphabetically



  • Name of the volume to be created

Size in GB


  • Size of the volume to be provisioned

  • Data size (snap reserve should be considered)


Name Description Status
