How to discover EMC Isilon Storage Systems?

Hi,

We have few EMC Isilon Storage Systems, which we would like to discover. Any input on how to do that would be appreciated.

Thanks,

Ashish

You can use two methods to discover Isilon Clusters:

Using a server-less horizontal discovery pattern, use the Isilon OneFS API to extract information via REST. You'll need both the Isilon REST endpoint URL (or IP address), port and a set of credentials to perform the REST queries. See the Isilon OneFS API Reference for more information on the type of information you can extract using REST.
Using a horizontal discovery pattern, use SNMP to query Isilon Clusters. I built a very basic pattern to discover an Isilon Cluster and create a CI with a Storage Server [cmdb_ci_storage_server] class. The pattern captures:
- Cluster hostname
- Chassis model
- Chassis serial number
- OneFS version
- File system volume and mount point
- Total and available space
- Storage devices and disks (name, model, serial number)
- Network adapters

An update set containing the pattern is attached below - note that it's supplied without warranty or support, and used at your own risk.

Of these two methods, the OneFS API allows you to extract information more readily than via SNMP. You may also want to review the OOTB CI classes to determine if they're adequate or whether custom CI classes may better model the Isilon cluster in the CMDB.

Hope this helps.

Tony, Which ServiceNow version are you running? We are running Istanbul. When I attempted to import the XML, the pattern appears as though it did not load. Wondering if it's due to a version mismatch.

The pattern was developed on Jakarta, so it could well be the reason why the update set wasn't applied successfully to your Istanbul instance.

I tested the update set with a Jakarta instance and it commits without errors and loads the pattern and probe correctly.

Tony - I've loaded the xml file but I don't see a probe, just the pattern, am I missing something?

Tony Branton · ‎11-18-2017

There's no probe. Other than the pattern there's an SNMP CI classifier - you should see this if you navigate to Discovery > CI Classification > SNMP and search for a record whose Name contains "Isilon".

Thanks for the clarification
