Storage discovery issues

[Rakesh16i]

Hi,

I am trying to discover storage devices and have configured CIM credentials. I have created a schedule with Storage IPs but discovery is not yielding any results. Unable to find what is the issue as the logs are not telling anyhting relevant to CIM. Then I found out the below notes from WIKI. In the point no 1 it says wbem port probe will be used as partof network discovery. So is network discovery is mandatory to disover storage? If so why should I go for it when i already know the IPs of storage devices

How CIM Discovery Works

1. The Shazzam probe launches the wbem port probe as part of network discovery.
2. The wbem port probe detects activity on target ports SLP 427, CIM 5989 and 5988, and then examines the Service Registry Queries related list, at Discovery Definition > Port Probes, for the SLP query. The base system provides this query is provided to detect the service:wbem service type, which indicates the presence of an SLP server.
3. The Shazzam probe launches a scanner for the WBEM service type. The scanner retrieves:
   • The attributes of the service from the SLP server.
   • The interop namespaces of CIM servers in the network.
4. The scanner appends the namespace values it finds to the port probe results.
5. The wbem port probe appends the SLP data it carries to the CIM Classify probe.
6. The CIM Classify probe uses that information to explore the CIM servers.

Regards,

That line is somewhat misleading, it's using the same Shazzam probe but it is not reliant on network discovery. The storage discovery connects to the WEBM IP but uses SMI-S / CIM for the actual discovery of storage system objects (LUNs, HBAs, WWPNs, etc).
