Description

Symmetrix arrays are automatically discovered when they are connected through HBA to the servers where EMC SMI-S provider (EMC Solutions Enabler) is installed. Because monitoring large storage arrays with a single SMI-S Provider may cause performance issues and affect the performance of the SMI-S provider itself, it is recommended to prevent some arrays from being automatically discovered.

Procedure

IMPORTANT: DO NOT use this method if the host where the EMC SMI-S Provider is installed also has ECC running.

To prevent EMC Symmetrix Arrays from being automatically discovered:

  1. Execute the following command to stop the EMC SMI-S provider service: 
    <install_dir>\ECIM\ECOM\bin\sm_service stop ecom.exe 
  2. Execute the command ‘SYMCLI\bin›symcfg list’ to list the SymmIDs
  3. In a file, list the SymmID of the Symmetrix arrays that should not be auto-discovered
  4. Save this file as ‘symavoid’ in the SYMAPI/config directory
  5. Delete the host’s SYMAPI database (the symapi_db_bin file) for the changes to take effect. The database will be recreated the next time the Storage Agent for Symmetrix tries to discover arrays.
  6. Execute the following command to start the EMC SMI-S provider service: 
    <install_dir>\ECIM\ECOM\bin\sm_service start ecom.exe
  7. Perform a discovery for the changes to take effect.
