VAST Data | Scan Requirements – Help Center | Core6

StorageGuard collects configuration data from VAST clusters by connecting to the VMS IP address and invoking read-only REST API calls over HTTPS.

Preparation for Scanning VAST Clusters

The following table lists the requirements for scanning VAST Clusters:

#	Description
1	Provide the VMS IP address.
2	Provide a VMS management (REST) username and password.
3	The VMS manager user should be assigned with a readonly role enabling it to run queries on all realms. Examples of read-only APIs used: `GET /clusters` `GET /vms` `GET /views`
4	Make sure that IP connectivity through HTTPS is available between the StorageGuard server and the VMS IP.

The following suggested method can be used to create a user account with appropriate privileges:

From the left navigation menu in the VAST Web UI, select Administrators and then Managers.
Click Create Managers.
In the Add Manager dialog, complete the manager's details.
Select the predefined Read-Only role or assign the View permission on all realms to the manager.

The manager can also be created using CLI:

manager create --username sguard --role-id {id of the predefined read-only role}
