Revert to a Product Snapshot

You can use the vRealize Suite Lifecycle Manager API to revert your vRealize Suite product to a snapshot created using vRealize Suite Lifecycle Manager. Reverting to a snapshot restores the product to a former state.

For example, if a product upgrade fails, you can revert to a snapshot of the product that you created before attempting the upgrade.

The following procedure shows how to revert to a snapshot for vRealize Operations Manager.

Prerequisites

Verify that all general prerequisites have been satisfied and that you have assigned your environment ID and product ID. See the prerequisites for Performing Day 2 operations using vRealize Suite Lifecycle Manager APIs.
Verify that you have the ID of the snapshot that you want to revert to. See Create a Product Snapshot.
If you are reverting to a snapshot of SaltStack Config or vRealize Business for Cloud, verify that the tenant ID variable is assigned. See Creating and Managing Product Snapshots.

Procedure

Assign the snapshot ID variable.
```
snapshotId = '<your_snapshot_ID>'
```

Revert vRealize Operations Manager to your_snapshot_ID. For a snapshot that was taken without memory, set "powerOn": true to power on the virtual appliance and restore the disk to its initial state.

curl -X POST \
  '$url/lcm/lcops/api/environments/$environmentId/products/$productId/snapshot/inventory/revert' \
  -H 'Authorization: Basic YWRtaW5AbG9jYWw6VGhpc0lzUGFzc3dvcmQ=' \
  -H 'Content-Type: application/json' \
  -d '{
     "powerOn": true,
     "productSnapshotId": "'$snapshotId'"
}' | jq "."

Note: To revert to a snapshot of SaltStack Config or vRealize Business for Cloud, include the tenant ID as a query parameter in your request, for example:

curl -X POST \
  '$url/lcm/lcops/api/environments/$environmentId/products/$productId/snapshot/inventory/revert?tenantId=$tenantId' \
  -H 'Authorization: Basic YWRtaW5AbG9jYWw6VGhpc0lzUGFzc3dvcmQ=' \
  -H 'Content-Type: application/json' \
  -d '{
     "powerOn": "true",
     "productSnapshotId": "'$snapshotId'"
}' | jq "."

The request triggers the API. The response shows the request ID.

{
    "requestId":"a3f77209-0005-44b3-9eb5-ac1a1ba19394"
}

Assign the variable for the requestId.

requestId = "a3f77209-0005-44b3-9eb5-ac1a1ba19394"

Use the requestId to track your request.
```
curl -X GET '$url /lcm/request/api/v2/requests/$requestId' -H 'Authorization: Basic YWRtaW5AbG9jYWw6VGhpc0lzUGFzc3dvcmQ=' | jq "."
```
After the request succeeds, vRealize Suite Lifecycle Manager has restored vRealize Operations Manager to the state and configuration defined in the snapshot.
```

  "outputMap": {},
  "state": "COMPLETED",
  "executionId": "59430b9d-44cc-47a1-90ec-777481edb9z9",
...
```
On Manage Snapshot in the vRealize Suite Lifecycle Manager product UI, a You are here marker shows the snapshot to which the product was reverted.
