Cause: ViPR SRM Isilon data collection won't work when using non-admin credential with the AuditAdmin role. When you put this url https://Isilon_IP:8080/platform/1/zones in the browser and use the non-admin account.
You will get Authentication error as below.

{
"errors" :
[

{
"code" : "AEC_NOT_FOUND",
"message" : "Path not found: /1/zones%20in."
}
]
}

Fix: To fix this issue you have to add the Service account; which you are using to discover the Isilon in ViPR SRM to the "Security Admin Group" role in Isilon Cluster.
>> login into Console > Click on "Access" > Select "Membership & Roles" > Click on "Roles" > Select "SecurityAdmin" > click on "View/Edit" > Click on "Edit Role" > "+ Add members to this role" > Search for the account > Select the account > Click on "Save Changes"

Verify: https://<HostName>:8080/platform/1/zones
Output: if the output is like below, it means it is working
