NetApp SolidFire storage system discovery
Summarize
Summary of NetApp SolidFire Storage System Discovery
ServiceNow Discovery leverages the NetApp SolidFire storage system discovery pattern to identify and map clusters and nodes within SolidFire storage systems. This enables comprehensive visibility and management of your storage infrastructure in the CMDB. To discover certain resources, ensure the latest Discovery and Service Mapping Patterns application is installed from the ServiceNow Store.

Prerequisites
- Keep the Discovery and Service Mapping Patterns, Visibility Content, and CMDB CI Class Models applications updated.
- Create a basic authentication credential alias for a SolidFire Cluster Admin user to facilitate secure discovery.
- Verify MID Server connectivity to the SolidFire devices to enable communication during discovery.
- Configure a serverless discovery schedule targeted at SolidFire clusters and nodes for efficient resource scanning.
Data Collected and CI Details
The discovery process populates detailed configuration item (CI) records in the CMDB across several tables, capturing essential attributes such as:
- Storage Server: Name, serial number, firmware version, IP address, OS version, manufacturer, model ID, and operational status.
- Storage Cluster: Name, IP address, cluster version (Element OS API), manufacturer, and operational status.
- Storage Cluster Node: Name, operational status, and cluster reference.
- Storage Node Element: Hardware details including chassis type, RAM, CPU type/manufacturer, serial number, and operational status.
- Disk: Device ID, serial number, storage type, size, manufacturer, model ID, and associated storage server.
- Network Adapter: Name, IP and MAC addresses, netmask, and linked storage server.
- IP Address: IP, netmask, and linked network adapter.
CI Relationships and References
The discovery pattern establishes important relationships to accurately represent the SolidFire environment topology, including:
- Clusters containing cluster nodes.
- Cluster nodes hosting storage node elements.
- Storage node elements managing clusters and allocating storage servers.
- Storage servers running clusters and containing disks and network adapters.
- Network adapters owning IP addresses.
References link CI records across tables to maintain data consistency and enhance impact analysis within the CMDB.
Practical Implementation
- Use the provided guidance to create a basic authentication credential alias specific to NetApp SolidFire discovery for secure access.
- Set up a dedicated serverless discovery schedule focused on SolidFire clusters and nodes to automate and optimize discovery runs.
Benefits for ServiceNow Customers
By implementing this discovery pattern, customers gain automated, detailed visibility of their NetApp SolidFire storage infrastructure within the CMDB. This enables improved asset management, operational status tracking, and relationship mapping critical for service impact analysis and change management. The structured data and relationships support accurate dependency views showing the interconnections between storage clusters, nodes, and components.
ServiceNow Discovery uses the NetApp SolidFire storage system discovery pattern to find clusters and nodes on the SolidFire storage system. Discovering some of these resources may require updating to the latest version of the Discovery and Service Mapping Patterns application from the ServiceNow Store.
