IBM Tivoli Storage Productivity Center sensor
The IBM® Tivoli® Storage Productivity Center sensor discovers storage resources that are related to a storage area network (SAN) and Network Attached Storage (NAS). The sensor extracts data from a Tivoli Storage Productivity Center database.
- Storage arrays
- Storage volumes
- Array and switch ports
- File systems
- Disk partitions
- NAS-related data
Some of these resources can also be discovered by the host storage sensor (for example, data that is related to hosts) and the Fibre Channel switch sensor (for example, data that is related to switches).
Sensor name that is used in the GUI and logs
To get mappings among the Storage resources (Storage disks, volumes, physical hosts, VM machines, SVController as STG virtualizer, FC switches and disks, etc..), the below schema details the prerequisites at TPC/Spectrum level and TADDM discovery level for each case:
Virtual Server (typically VMware virtual machines) and storage LUNs resources mapping
The relationship can be obtained after both these sensors- HostStorageSensor and TPCStorageServerSensor run successfully.
However, we need to keep into consideration the prerequisites and limitations of both the sensors.
For prerequisites of the Host Storage sensor, please refer to the link below: https://www.ibm.com/support/knowledgecenter/en/SSPLFC_7.3.0/com.ibm.taddm.doc_7.3/SensorGuideRef/r_cmdb_sensor_hoststorage.html
For prerequisites of the TPC Storage sensor, please refer to the link below: https://www.ibm.com/support/knowledgecenter/en/SSPLFC_7.3.0/com.ibm.taddm.doc_7.3/SensorGuideRef/r_cmdb_sensor_tpcstorage.html
Storage Subsystems and storage LUNs resources mapping
This is an implicit relationship which is shown if the Storage Subsystem is correctly discovered.
Physical Servers and Storage Subsystems resources mapping
This can be obtained from HostStorageSensor. However, we need to keep into consideration the prerequisites and limitations of HostStorageSensor.
Storage Subsystems Volumes and Target Endpoint Mapping
To get the mapping from Storage Subsystems volume discovered by TADDM (through the TPC Storage sensor) to the endpoint target servers, TPC will need the TPC SRA agents installed on targets hosts accessing those volumes, since TADDM needs at least the MAC address with the hostname of the target host to display it as accessing specific volumes. Other alternative is using HostStorageSensor for each of the target hosts to store and display the mapping information.
