Manually reactivating the environment

You learn how to reactivate the AWS or Azure environment.

Follow this procedure to reactivate the AWS environment or reactivate the Azure environment, and then ensure the reactivated environment is configured the same as the deactivated one. You must add the activated parameters that were backed-up and documented in the previous steps to the new reactivated environment.

Using the CDP CLI🔗

You parameterize the CLI create-cluster command to activate the cluster, as described in the CLI documentation.

Activate the cluster by passing the options you retrieved backing up AWS or activating Azure.

To see all options run the following command.

cdp dw create-cluster –help

Examples for shorthand and JSON syntax are available.

For example, an Azure CLI activation option looks something like this:

cdp dw create-cluster --environment-crn <crn:cdp:environments:us-west-1:abc:environment:123> \
--use-overlay-network --no-use-private-load-balancer \
--azure-options \
userAssignedManagedIdentity="<full managed identity identifier>",subnetId="<full subnet identifier>",enableSpotInstances=false,logAnalyticsWorkspaceId="<full log analytics workspace identifier>" \
--profile <customer profile>

An AWS CLI activation option looks something like this:

cdp dw create-cluster --environment-crn <crn:cdp:environments:us-west-1:abc:environment:123> \
--use-overlay-network --use-private-load-balancer \
--aws-options \
lbSubnetIds=<list of subnet identifiers>,workerSubnetIds=<list of subnet identifiers>,enableSpotInstances=false --profile <customer profile>

(Optional) If you need to preserve the old environment URL, specify the custom subdomain in the dw create-cluster command.
```
--custom-subdomain (string)
```
For example:
```
--custom-subdomain env-qwertyu.dw
```

For more information about cluster URLs after reactivation, see “Cluster URLS after reactivation”. For more information about the CLI, see CDP CLI documentation.

Using the Cloudera Data Warehouse UI🔗

In the Cloudera Data Warehouse service, in Environments, search for and locate the environment that you want to activate.
Click Activate to activate the environment.
The default Database Catalog is created. When the Cloudera Data Warehouse cluster is restored, the IDs of the environment and Database Catalog change.
In the Activation Settings, configure the environment using the information you gathered when you backed up activation parameters.
(Optional) If you need to preserve the old environment URL, specify the custom subdomain.
In Custom Environment Subdomain, if the environment is env-qwertyu.dw, for example, specify the custom subdomain in the following format:
```
<old environment identifier>.dw
```
