Isilon OneFS 8.1 has two possible ESRS configurations, one for ESRS v2, and one for ESRS v3. The v3 requires a username and password. Attempting to enable the v3 configuration with the wrong user name and password will result in the ESRS gateway sending ‘401’ errors back to the cluster.
Example of the error when enabling the ESRS v3 configuration on the cluster:
The issue is outside of Isilon’s control and is dependent upon configuration between ESRS and the Support EMC site. The error showing in the cluster logs, are actually errors the ESRS gateway is sending back to Isilon.
Enabling the ESRS v3 configuration on the cluster requires using the same Support EMC site credentials. The Support EMC credentials are the same ones used when logging into the website to manager Service Requests, search KBs, or download files.
If the credentials being used do not match that of the site, or if the credentials aren’t working or unknown. Engage with the Account team responsible for the site that is using the ESRS gateway. Changes may be required or related to ESRS itself, updates to the Customer Site information, the Install Base, or even changes to the account privileges associated with the Support EMC site.
Also, for the ESRS v3 configuration to work on Isilon, requires a signed and valid license.
