How to discover EMC Isilon Storage Systems?

wowashish · ‎08-29-2017

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.

I think it has to do with my CI Identifier rule for Storage Server. I"m getting this message:

In payload invalid data source [ServiceNow] exist. You need to provide a valid choice value from field [discovery_source] in table [cmdb_ci],

Working myway through it.

Figured it out, it was a system choice that needed to be added

Good to hear - let me know what system choice you needed to add.

I'll be interested to hear your feedback on the information returned by Discovery, in particular:

Whether the CI class is adequate (suggest a more appropriate one if applicable)
Missing objects, how they relate to the parent CI, and which CI classes would best represent them
Attributes no picked up by the pattern that would be important to track (assuming they can be queried via SNMP)

Thanks for trying out the pattern!

Thanks Tony, this is working great, now just trying to understand from the team how we can tell what applications/servers are mapped to the Isilon's.

Identifier: Horizontal discovery pattern not found: Isilon-SNMP

This is the error I get running against the IP address..

The update set installed fine in Istanbul.
