I'm trying to discover an EMC Isilon storage server.
SNMP classification goes fine, EMC Isilon pattern is launched, but fails when interrogating the REST interface with an error 401 (unauthorized).
I am able to interrogate the same REST url using the same credentials as configured in Discovery, using a simple browser, with no error and getting the expected response.
I've configured the credentials with copy/paste so the probability of a typo is 0.
Any idea would be welcome.

I had read those before. The question is : why can't the pattern connect (HTTP basic) to the REST interface of the server while I can with a browser, using the same url and credentials ?

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.
Thanks
