Connecting storage enclosures to a storage subsystem
To connect storage enclosures to the storage subsystem, complete the following
steps:
1. Follow the instructions in the IBM System Storage DS3500 and EXP3500 Rack
2. Select a cabling topology applicable to the number of ESMs in the storage
3. Follow the cabling diagram for the selected topology.
4. If required, set unique enclosure IDs for all storage enclosures that are cabled to
The DS3500 storage subsystem locates the drives in the storage enclosures after
you power-on the configuration. Always turn on the storage enclosures first and
then turn on the DS3500. After you have powered-on the configuration, use the
Storage Manager software to check the status of the new drives, correct any errors,
and configure the new drives.
