Discovery can find information about a UNIX or Linux host and attached
storage.

## Before you begin

Role required: discovery_admin

## Procedure

1. **Optional:** On the host, assign elevated privileges to the account that Discovery will use.
2. On the ServiceNow instance, [add
   credentials](https://www.servicenow.com/docs/access?context=t_CreateCredential&version=yokohama&pubname=yokohama-platform-security&ft:locale=en-US) to the Discovery Credentials table.
3. Create a Discovery Schedule for each host IP address.
4. **Optional:** Create a behavior that uses a functionality definition with a wbem port probe to make the initial port-scanning phase (Shazzam) more efficient.
5. Run network discovery.  
   Note:  
   If the host also connects to a NAS or SAN storage array, set up the [SMI-S Provider](https://servicenow-prod.fluidtopics.net/62fNAVLDZXumnwuj2dZbvw "Use this procedure for configuring a standalone storage device with the required SMI-S Provider for Discovery.") and [CIM
   credentials](https://www.servicenow.com/docs/access?context=r_CIMCredentialsForm&version=yokohama&pubname=yokohama-platform-security&ft:locale=en-US).
