Storage relationships
Discovery establishes the correct relationships between Network-Attached Storage (NAS)
storage devices and remotely mounted client servers that consume the storage. Discovery maps
NAS file shares. It maps by taking the IP or hostname of a remote mounted disk on the client
computer. It then matches it to the IP or hostname of the storage server providing the
exported file system.
Discovery creates the following relationships for storage CIs running on Storage Area
Networks.

Discovery maps NAS file shares. It maps by resolving the hostname of a remote mounted disk
on the client computer to an IP address. It then matches it to the IP address of the storage
server that provides the exported file system. Discovery extracts the hostname or IP address
from the NAS path to determine the identity of the storage server. If the hostname is an
actual hostname, the system immediately resolves that value into an IP address. It also
stores it in the nas_ip_address field of the NAS File System
[cmdb_ci_nas_file_system] table.
Discovery creates the following relationships for storage CIs running on Network Attached
Storage (NAS). These relationships are the same between Linux and Windows operating system
hosts.
