Manage First Class Disk Snapshots

To create a snapshot of a First Class Disk (FCD), you make a POST request with the block device ID of the FCD. Using the snapshot ID created, you can revert an FCD to a snapshot or delete a snapshot of an FCD.

Verify that all general prerequisites and prerequisites for the

Automation Assembler

Infrastructure as a Service (IaaS) service have been satisfied. See Prerequisites for API Use Case Examples.

Verify that you have created an FCD and you have a block device ID. See Create a First Class Disk.

Assign the block device ID variable.

block_device_id='<your_block_device_id>'

Create a snapshot of the FCD.

curl -X POST \
  $url/iaas/api/block-devices/$block_device_id/operations/snapshots?apiVersion=$api_version \
  -H 'Content-Type: application/json' \
  -H "Authorization: Bearer $access_token" \
  -d '{
    "description": "example description"
  }' | jq "."

The response includes a selfLink value.

{
  "progress": 0,
  "status": "INPROGRESS",
  "name": "Provisioning",
  "id": "example-selfLink-alphanumeric-string",
  "selfLink": "/iaas/api/request-tracker/example-selfLink-alphanumeric-string"
}

Assign the selfLink variable.

selfLink_id='example-selfLink-alphanumeric-string'

Use the selfLink to track the progress of the FCD snapshot creation.

curl -X GET -H 'Content-Type: application/json' -H "Authorization: Bearer $access_token" $url/iaas/api/request-tracker/$selfLink_id?apiVersion=$api_version | jq "."

The response indicates if the snapshot is successful.

{
  "progress": 100,
  "message": "success",
  "status": "FINISHED",
  "resources": [
    "/iaas/api/block-devices/your-block-device-id"
  ],
  ...
}

To create additional FCD snapshots, repeat #GUID-CC4FAC80-584C-4B25-AD62-1FFE8809E2F9_STEP_722CF989-37EC-4969-B983-DD1C27E56201-en to #GUID-CC4FAC80-584C-4B25-AD62-1FFE8809E2F9_STEP_2CDEF3CD-C103-4D45-8C84-F00F01E5089F-en.

To get a snapshot ID, list all FCD snapshots.

curl -X GET -H 'Content-Type: application/json' -H "Authorization: Bearer $access_token" $url/iaas/api/block-devices/$block_device_id/snapshots?apiVersion=$api_version | jq "."

If you created multiple snapshots, the response lists multiple snapshot IDs.

Examine the response and select a snapshot ID to assign as a variable.

snapshot_id=<your_snapshot_id_1>

You can list an individual snapshot.

curl -X GET -H 'Content-Type: application/json' -H "Authorization: Bearer $access_token" $url/iaas/api/block-devices/$block_device_id/snapshots/$snapshot_id?apiVersion=$api_version | jq "."

You can revert an FCD to a snapshot.

curl -X POST \
  $url/iaas/api/block-devices/$block_device_id/operations/revert?id=$snapshot_id\&apiVersion=$api_version \
 -H 'Content-Type: application/json' \
 -H "Authorization: Bearer $access_token" \
 -d '' | jq "."

To track the progress of the reversion, perform #GUID-CC4FAC80-584C-4B25-AD62-1FFE8809E2F9_STEP_533302B9-3B9A-4770-8D97-2C0E3968F5AE-en and #GUID-CC4FAC80-584C-4B25-AD62-1FFE8809E2F9_STEP_2CDEF3CD-C103-4D45-8C84-F00F01E5089F-en.

You can delete a snapshot.

curl -X DELETE -H 'Content-Type: application/json' -H "Authorization: Bearer $access_token" $url/iaas/api/block-devices/$block_device_id/snapshots/$snapshot_id?apiVersion=$api_version | jq "."

Create snapshots of a First Class Disk and revert an FCD to a snapshot

With the block device ID from the created FCD, create multiple snapshots of an FCD.

$ url='https://appliance.domain.com'
$ api_version='2021-07-15'
$ block_device_id='e1cbc8e1-76bb-4bef-8e51-a582437266c2'

Create a snapshot of the FCD.

$ curl -X POST \
  $url/iaas/api/block-devices/$block_device_id/operations/snapshots?apiVersion=$api_version \
  -H 'Content-Type: application/json' \
  -H "Authorization: Bearer $access_token" \
  -d '{
    "description": "Example description 1"
  }' | jq "."

The response provides a selfLink to the request.

{
  "progress": 0,
  "status": "INPROGRESS",
  "name": "Provisioning",
  "id": "d08bb46c-cf7e-40b6-bdf8-893390ba4d51",
  "selfLink": "/iaas/api/request-tracker/d08bb46c-cf7e-40b6-bdf8-893390ba4d51"
}

Assign the selfLink ID variable.


$ selfLink_id='d08bb46c-cf7e-40b6-bdf8-893390ba4d51'

Track the progress of the request.


$ curl -X GET -H 'Content-Type: application/json' -H "Authorization: Bearer $access_token" $url/iaas/api/request-tracker/$selfLink_id?apiVersion=$api_version | jq "."

Create a second snapshot of the FCD.

$ curl -X POST \
  $url/iaas/api/block-devices/$block_device_id/operations/snapshots?apiVersion=$api_version \
  -H 'Content-Type: application/json' \
  -H "Authorization: Bearer $access_token" \
  -d '{
    "description": "Example description 2"
  }' | jq "."

List all the snapshots of the FCD.

curl -X GET -H 'Content-Type: application/json' -H "Authorization: Bearer $access_token" $url/iaas/api/block-devices/$block_device_id/snapshots?apiVersion=$api_version | jq "."

Examine the response to see all snapshot IDs.

Assign a snapshot ID variable.

snapshot_id='16cfdbb8-559c-49ff-8162-0a4c57079c81'

List information about the snapshot.
