Cleaning up deployed environments

You can clean up the IBM Spectrum LSF cluster from the environment if no longer needed. The process is in three phases:

Destroy all the associated VPC resources and remove them from your IBM Cloud account
Remove the workspace
Verify that the cluster is free of running jobs or working compute nodes

Destroying resources by using the UI

In the IBM Cloud console, navigate to Projects > project_name > Configurations > project_configuration_name > Resources tab, and click the link for the workspace, and select Actions > Destroy resources to delete all of the related VPC resources that were deployed as part of that workspace.
If you select the option to destroy resources, decide whether you want to destroy all of them. This action cannot be undone.
Confirm the action by entering the workspace name in the text box and click Destroy.

If successful, the Jobs view, you should see a Workspace destroy successful message. If unsuccessful, Schematics throws an error and shows a failure status.

Deleting a workspace by using the UI

In the IBM Cloud console, the navigate to Projects > project_name > Configurations > project_configuration_name > Resources tab, and click the link for the workspace, and select Actions > Delete workspace to delete the workspace.
Confirm the action by entering the workspace name in the text box and click Delete.

If unsuccessful, Schematics throws an error and shows a failure status.

Verify that the cluster is free of running jobs and working compute nodes.

Verify that it is safe to destroy resources:

As the lsfadmin user, close all LSF queues and kill all jobs:
```
badmin qclose all
bkill -u all 0
```
Wait ten minutes (this value is the default idle time), and then check for running jobs:
```
bjobs -u all
```
Look for a No unfinished job found message.
Check that no working compute nodes (only management nodes) are listed:
```
bhosts -w
```

If the cluster has no running jobs and no working compute nodes, then it is safe to destroy resources from this environment.

Destroying resources by using the CLI

Log in to the IBM Cloud CLI.
Run the following command to remove your VPC resources from your workspace:
```
ibmcloud schematics destroy --id <workspace_ID>
```

You can monitor the log files to view the deletion progress of all IBM Cloud resources.

Deleting a workspace by using the CLI

Run the following command to delete your workspace:

ibmcloud schematics workspace delete --id <workspace_ID>

You can monitor the log files to view the deletion progress of your workspace.

If unsuccessful, Schematics throws an error and shows a failure status.
