EMC Storage Scope sensor

The EMC Storage Scope sensor discovers storage resources that are related to storage area network (SAN) by extracting data from an EMC Storage Scope database.

The sensor discovers such storage resources as storage arrays, hosts, switches, fabrics, zones, storage volumes, switch ports, file systems, and disk drives. Some of those resources, like data that is related to hosts or to switches, can also be discovered by the Host storage sensor or the Fibre Channel switch sensor.

The EMC discovery is performed by two sensors, the EMC Storage Scope sensor and the EMC Storage Scope Detail sensor. The first one discovers general attributes of StorageSubSystem and full details of FC Switch, Fabric, Zone and ZoneSet. Then, the sensor starts the Detail sensor that discovers details of EMC arrays and hosts. You can specify the number of arrays discovered by each of the Detail sensors by editing the arraysDiscoveryChunk parameter.

Prerequisites

  • You must copy the following Oracle JAR files from the discovery endpoint to the dist/osgi/plugins/com.ibm.cdb.discover.sensor.app.srm.emccommon_1.0.0/lib/oracle directory:
    • ojdbc14.jar
    • oraclepki.jar
    • ojpse.jar

Limitations

  • To avoid duplicates, you must run the Level 2 discovery of endpoints that are discovered by EMC Storage Scope sensor.
  • To reduce the number of discovered objects that might result in the Out of Memory errors, the EMC Storage Scope Detail sensor discovers only one SCSI Path for each Volume, even if more are available. Agile Service Manager uses the SCSI Paths to create relationship between a computer system and a Storage SubSystem. The Paths are retrieved from the SRMHostArrayPath table.
  • When you run a discovery, StoragePools are not discovered.

Security issues

  • If you enable SSL on the EMC Oracle database, you must add the cwallet.sso file to the access list.
