Select **Submit**. - **Verify the configuration of a Serverless Discovery schedule** role: Discovery\_admin. 1. Navigate to **Discovery** > **Discovery Schedules**. 2. Select **New**. 3. Fill in the fields in the form. |Field|Description| |-----|-----------| |Name|Fill in the name of your choice.| |Discover|In the list, select `Serverless`.| |MID Server|Select the search button to open the list of MID Servers and select the MID Server that has network access to the DDMC.| |Active|Enabled by default.| |Credential alias|No need to configure this field.| For more information about setting the **Max run time**, **Run**, and **Time** fields, see: [Schedule a horizontal discovery](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/it-operations-management/discovery/t_CreateADiscoverySchedule.md) 4. Select **Submit**. - **Associate the __Dell EMC Data Domain__ pattern with the Serverless Discovery schedule** role: Discovery\_admin. 1. Navigate to **Discovery** > **Discovery Schedules**. 2. Select the schedule that you configured. 3. Select the **Serverless Execution Patterns** tab. 4. Select **New**. 5. Fill in the fields in the form. |Field|Description| |-----|-----------| |Name|Fill in the name of your choice. For example: `dell_emc_data_domain_serverless_discovery`| |Pattern|Select the search button to open the list of patterns, and select the **Dell EMC Data Domain** pattern.| |Proxy Host|No need to configure this field.| |Extended Parameters|No need to configure this field.| 6. Select **Submit**. - **Configure the parameters for the __Dell EMC Data Domain__ pattern** role: Discovery\_admin. 1. Navigate to **Discovery** > **Discovery Schedules**. 2. Select the schedule that you configured. 3. Select the **Serverless Execution Pattern** tab. 4. Select the record created for the **Dell EMC Data Domain** pattern. 5. In the **Discovery Pattern Launcher parameters** tab, set the value for the fields as follows:
Field Description
Credential Alias Fill in the alias ID configured for DDMC. You can find the alias in the **Connection & Credential Aliases** list. For example: `ddmc_credential_alias_id`.
DDMC Port \(Optional\) by default the pattern uses port 3009.
DDMC IP Address Fill in the host name or the IP Address of the DDMC. These details can be provided by the DDMC Admin. For example: `101.10.10.101` or `ddmc.demo.local`.
6. To run the discovery, you can select **Discover now** from the **Related Links** or wait for the run time. ## Data collected by Discovery during horizontal discovery Discovery populates the data in the CMDB when running the **Dell EMC Data Domain** Patterns.
Field Description
Name \[name\] The unique identifier of the storage server. The name is typically the Domain Name System \(DNS\) hostname or the computer name, which corresponds to the **host\_name** attribute.
Host Name \[host\_name\] The DNS hostname of the Data Domain system. The host that is used to register the system with the Data Domain Management Center \(DDMC\).
FQDN \[fqdn\] The Fully Qualified Domain Name of the Data Domain system. The complete domain name used to register the system with the DDMC.
IP Address \[ip\_address\] The IP address of the Data Domain storage server. The name is the specific IP address used to register the Data Domain system with the DDMC.
OS Version \[os\_version\] The version of the operating system running on the Data Domain system. The versions supported are from DD OS 7.3.
Model \[model\] The specific model of the Data Domain \(DD\) system. For example, the name for the DD Virtual Edition \(VE\) is **DELL EMC DD VE**.
Manufacturer \[manufacturer\] The manufacturer is Dell EMC.
Serial Number \[serial\_number\] The unique serial number assigned to the DD system.
Operating System \[os\] The Data Domain OS is: **DD OS**.
Field Description
Name \[name\] The name of the DDMC associated with the storage cluster.
Cluster ID \[cluster\_id\] The universally unique identifier \(UUID\) of the DDMC, which uniquely identifies the cluster.
Cluster Version \[cluster\_version\] The software version of the DDMC that is currently installed on the cluster.
Serial Number \[serial\_number\] The unique serial number assigned to the Virtual Data Domain Management Center \(VDDMC\) system.
Model ID \[model\_id\] The specific model of the Data Domain system in use. For the DDMC, the model ID is 'DELL EMC DD Management Center'.
Manufacturer \[manufacturer\] The manufacturer is Dell EMC.
Field Description
Name \[name\] The name assigned to the disk device within the storage system.
Device ID \[device\_id\] The unique identifier for the disk device, which is the same as the device name.
Model ID \[model\_id\] The model of the disk device. For example: **VMware Virtual\_disk**.
Size \[size\] The capacity of the disk device, measured in gigabytes \(GB\).
The Disk Shelf Chassis database is populated only for physical DD systems that support disk expansion shelves.
Field Description
Name \[name\] The name of the disk expansion shelf.
Serial Number \[serial\_number\] The unique serial number of the disk expansion shelf.
Field Description
Serial Number \[serial\_number\] The unique serial number of the Dell EMC Data Domain storage system, as registered in the DDMC.
Serial Number Type \[serial\_number\_type\] The format of the serial number for the Dell EMC Data Domain storage system, indicating whether it's a system serial number or a Universally Unique Identifier \(UUID\).
Valid \[valid\] The validity of the data, with a value of **true** confirming that the serial number has been successfully verified.
Field Description
Name \[name\] The identifier or label of the network adapter, such as **eth1**.
The DDMC REST API doesn’t provide the MAC address of network adapters. As a result, the MAC address field for network adapters remains empty.
Field Description
IP Address \[ip\_address\] The IP address that is assigned to the device.
Netmask \[netmask\] The netmask associated with the IP address, defining the subnet to which the IP address belongs.
