Dell EMC XtremIO storage array discovery

ServiceNow Discovery uses the Dell EMC XtremIO storage array pattern to find Dell EMC XtremIO storage array components. Discovering some of these resources requires updating the Discovery and Service Mapping Patterns application from the ServiceNow Store.

Request apps on the Store

Visit the ServiceNow Store website to view all the available apps and for information about submitting requests to the store. For cumulative release notes information for all released apps, see the ServiceNow Store version history release notes.

Prerequisites

Discovery and Service Mapping Patterns store app

Verify the Discovery and Service Mapping Patterns store app, version 1.0.96, is installed.

Verify the CMDB CI Class Model, version 1.42.0, is installed.

Note: The Dell EMC XtremIO storage array pattern 1.0.96 store version was tested only for XtremIO cluster type X2.

Credentials

Grant Basic Auth permissions by configuring Basic Auth credentials for RESTful API. Save the admin credentials as Basic Auth credentials to ensure a proper access.

Run Discovery

Run Quick Discovery by Target IP. Provide the IP of the XMS (that manage the storage).

Permissions for REST API queries

During the discovery, the pattern uses the following API queries. The user that is added to the credentials in the instance must have permissions to run these queries.
