Discovering some of these resources might require updating to the latest version of the Discovery and Service Mapping Patterns application from the ServiceNow Store.\n\n## Request apps on the Store\n\nVisit the [ServiceNow Store](https://store.servicenow.com/sn_appstore_store.do#!/store/home) 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](https://www.servicenow.com/docs/r/store-release-notes/sn-store-release-notes.html).\n\nTo learn about PowerMax storage components and their versions that you can discover, refer to [Detailed information on products discovered by ITOM Visibility](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/it-operations-management/itom-visibility/r_SupportedApplications.md).\n\n## Prerequisites\n\n- **Verify that the applications are up to date**\n\n Discovery and Service Mapping Patterns\n\n CMDB CI Class Models\n\n- **Verify the creation of the credential alias**\n 1.
