IBM DS3500

Adding an expansion enclosure to a running dual-controller
configuration
The following procedures provide instructions for adding expansion enclosures to a
running dual-controller DS3500 storage subsystem.
Note: Make sure that each expansion enclosure has two ESMs before you connect
it to a dual-controller DS3500 storage subsystem. The second ESM must be
purchased separately. Contact your IBM marketing representative or
authorized reseller for more information about purchasing a second ESM.
For more information about installing a second ESM, see the Installation
Guide that comes with the expansion enclosure.
