Unable to discover SAN devices.

[Sudhakara Redd2]

Hi,

I am currently working on Discovery. As part of discovery, I am able to discover few storage devices but not SAN storage devices.

From ECC queue, I can see device name and Model but it is not creating the CI record. I am getting warning as "Name of unclassified CI is "xyz" and ECC queue stops at SNMP - Classify: 296 OIDs. Could you please assist me if someone created SAN devices?

Hi Sudhakar,

You are getting this error because the System OID of the particular device is not added into the discovery_snmp_oid table. Also, I don't think there is a defined SNMP classification for any Storage device in the discovery_classy_snmp table.

If your storage server supports SNMP then you can add the System OID into discovery_snmp_oid table and you need to define a new SNMP classification in the discovery_classy_snmp table.

Create a Discovery CI classification

Hi Vivek,

I have added SNMP OID for 1.3.6.1.4.1.1588.2.1.1.66 . with Model and Manufacturer in Dev environment. Yes it is creating CI as XYZ but it is not fetching any further information about the device like disks, serial numbers,CIM Object Path and any relationship data. Additionally it is also creating empty CI records without CI and model information.

and in the logs, completed activity, it is saying Identified CI and updating but it never got updated. Any help must appriaciated

Hi Sudhakar,

Yes! you won't find much information because there is no exploration probe present OOB for Storage discovery from SNMP.

To add more information you need to have MIB file from the particular vendor and that MIB file needs to be uploaded into ServiceNow. Also, you need to find out the OID's for Disks, serial numbers and whatever information you need. This OID information also you need to get it from the device vendors, they might have some document for that. Also, you can ask your network team if they are monitoring the SAN by SNMP if they are then they might have the OID's to explore more about the device. Based upon the OID's you need to create custom probes and sensors for ServiceNow to update in CMDB.
