How to discover storage devices?

[Subhamoy Maitr1]

I need to discover the following storage devices:

Mass Storage Device
Storage Device
Storage HBA

I need the following information:

1. Which ports are needed for this discovery?

2. What type of credentials (Windows/SSH/SNMP) are needed?

3. Any specific application needed to be installed on the mid server?

4. How to map the data to the corresponding tables?

[Rahul Priyadars]

refer below docs for Storage Discovery and MAP what is there in your environment.

CIM Probe uses SLP 427, CIM 5989 and 5988 ports.

2. What type of credentials (Windows/SSH/SNMP) are needed? --> CIM credentials are majorly used for storage discovery. However, snmp can also be used where SMI-S or CIM based discovery is not possible. The attached storage of windows/Linux servers are taken care of by the server discovery using windows/ssh credentials and you don't need to worry about it. After both the server and its storage host are discovered, the relationship is also established.

3. Any specific application needed to be installed on the mid server?--> The storage discovery needs SMI-S to be installed and running on the target host. Ask your storage team if that's the case in every device type you're trying to discovery. If that is the case, you just need CIM credentials (credentials of local user with read rights to the system and ports mentioned by Rahul to be opened from the MID server)

If not, you can look into installing the SMI-S on MID server to get a comprehensive discovered data. Or you can just have a snmp discovery on the storage devices to get minimal data on the same.

4. How to map the data to the corresponding tables? --> If it is OOB, you don't need to map any data, servicenow automatically takes care of it. However, if there are customizations, you may need to specify the table in your classifier (usually Storage server in case of snmp based discovery on Storage devices)

1. Which ports are needed for this discovery? https://docs.servicenow.com/bundle/paris-it-operations-management/page/product/discovery/concept/c_Storage.html

SMI and CIM has there own requirements.

2. What type of credentials (Windows/SSH/SNMP) are needed? CIM, Basic authentication and NAS requires SNMP.

3. Any specific application needed to be installed on the mid server? No, connectivity between storage server and servicenow mid.

4. How to map the data to the corresponding tables? Handled in ServiceNOw by patterns already.
