Create volume using iSCSI

07/05/2024 Contributors

You can use this workflow to create a volume accessed through iSCSI protocol.

Choose the workflow to use based on the type of Cloud Volumes ONTAP deployment:

Single Node
HA pair

Create volume using iSCSI for single node

You can use this workflow to create volume using iSCSI for a single node system.

There are two workflows available depending on whether a new or existing iGroup is used. You need to select the correct workflow:

Create volume using iSCSI with a new iGroup
Create volume using iSCSI with an existing iGroup

Create volume using iSCSI with a new iGroup

If the properties aggregateName and maxNumOfDisksApprovedToAdd are not provided on the REST API call, the response will fail with a suggested name for the aggregate and the number of disks needed to fulfill the request.

Step 1. Select the working environment

Perform the workflow Get working environments and choose the publicId value for the workingEnvironmentId parameter and the svmName value for the svmName parameter.

Step 2. Select the aggregate

Perform the workflow Get aggregates and choose the name for the aggregateName value.

Step 3. Choose the size for the disk

Choose the size value for the size:size parameter. The size:unit must be one of the following: TB, GB, MB, KB, or Byte.

Step 4. Choose the iscasiInfo parameters

You must choose the following values for the REST API call:

A unique igroup name for igroupCreationRequest → igroupName parameter
The required iqn’s to igroupCreationRequest → initiators parameter.
The required operating system for the osName parameter from one of the following:
- windows
- linux
- vmware
- windows_2008
- windows_gpt

Step 5. Create the quote

Perform the workflow Create quote. This is a recommended step but is not mandatory.

Step 6. Create the volume

You can issue the REST API call to create a volume.

HTTP method and endpoint

This REST API call uses the following method and endpoint.

HTTP method	Path

curl --request POST \
--location "https://cloudmanager.cloud.netapp.com/occm/api/vsa/volumes" \
--header 'Content-Type: application/json' \
--header 'x-agent-id: <AGENT_ID>' \
--header 'Authorization: Bearer <ACCESS_TOKEN>' \
--d @JSONinput

Additional input parameters

The JSON input example includes the minimum list of parameters.

Parameter Type Required Description

Parameter	Type	Required	Description
<SVM_NAME> `(svmName)`	Query	Yes	Identifies the SVM
`workingEnvironmentId` <WORKING_ENV_ID>	Query	Yes	Identifies the working environment ID
