Discovered CITs and Relationships

This section describes SOM storage entities in UCMDB:

  • Fibre Channel Connect. Represents a fibre channel connection between fibre channel ports.
  • Fibre Channel Port. Has change monitoring enabled on parameters such as state, status, WWN, and trunked state. Since a Fibre Channel Port is a physical port on a switch, it inherits from the Physical Port CIT under the NodeElement Resource CIT.
  • Fibre Channel Switch. Falls under the Node CIT because SOM maintains an IP address for each switch. Parameters such as status, state, total/free/available ports, and version are change monitore
  • Logical Volume. Represents volumes on storage arrays with change monitoring on availability, total/free/available space, and storage capabilities.

  • Storage Array. Represents a storage array with change monitoring on details such as serial number, version, and status. Since a storage array may not have a discoverable IP address, it inherits from the Network Device CIT.

  • Storage Fabric. Inherits from the Network Resource CIT and represents a storage fabric. This CIT has no change monitoring enabled.
  • Storage Processor. Represents other storage devices such as SCSI controllers, and inherits from the Host Resource CIT. A Storage Processor CIT monitors change on parameters such as state, status, version, WWN, roles, power management, and serial number.
  • Storage Pool. Storage Pool information is also collected from each storage array. This data collection populates a map as shown here:
