Dell EMC Isilon discovery

The ServiceNow Discovery application uses the Dell EMC Isilon pattern to find components of Dell EMC Isilon. Discovering some of these resources may require updating to the latest version of the Discovery and Service Mapping Patterns application from the ServiceNow Store.

For a complete list of devices and applications that ITOM Visibility can discover, see Detailed information on products discovered by ITOM Visibility.

Request apps on the Store

Visit the ServiceNow Store 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

Create SNMP Community credentials

Create an SNMP Community credential for the Isilon cluster. The discovery process begins with using SNMP-based queries to classify an application as an Isilon cluster. For more information, see SNMP community credentials in SNMP credentials.

Verify Dell EMC Isilon user permissions and roles

Once the application is classified as an Isilon cluster, the discovery process uses REST queries to find information about it. Provide the Dell EMC Isilon user with the following REST API endpoints:

• "https://" + $host + ":8080/platform/3/cluster/config”
• "https://" + $host + ":8080/platform/3/network/interfaces”
• "https://" + $host_ip + ":8080/platform/3/cluster/nodes/”
• “https://” + $host + ":8080/platform/3/zones”
• "https://" + $host + ":8080/platform/3/network/pools”
• "https://" + $host + ":8080/platform/3/storagepool/nodepools”
• "https://" + $host + ":8080/platform/3/storagepool/storagepools”
• "https://" + $host + ":8080/platform/3/protocols/nfs/exports”
• "https://" + $host + ":8080/platform/3/protocols/smb/shares"

The Dell EMC Isilon user must also have the following roles:

• ISI_PRIV_LOGIN_PAPI
• ISI_PRIV_AUTH
• ISI_PRIV_DEVICES
• ISI_PRIV_NETWORK
• ISI_PRIV_NFS
• ISI_PRIV_SMARTPOOLS
• ISI_PRIV_SMB

Create basic authentication credentials

In the Credentials module of the ServiceNow platform, create a basic authentication credential for the same Dell EMC Isilon user. For more information, see Basic authentication credentials.
