Rediscovering resources

Use this procedure to invoke the Auto-Discovery tool to import a resource into the database that has previously been discovered.

Before you begin

Read the following information before beginning this procedure:

  • General information
    • Management of the network using Netcool Configuration Manager requires network resources to be imported. Often, the VTMOS for a resource is unknown.
    • The Auto-Discovery tool in Netcool Configuration Manager 'discovers' the VTMOS of each network resource, allowing the import to take place without prior knowledge of the VTMOS credentials. Either the IP address or the DNS name of the resource is used instead.
    • If a network device previously fails to discover correctly, re-discover can be used to update the VTMOS information for that device.
    • If re-discover is used against an already successfully discovered device an import UOW is created.
  • About discovering head end devices
    • The Auto-Discovery tool does not support the importing of head end devices.

      To import head end devices, see Importing resources.
