Storage DS3500 In this chapter, we introduce the new IBM System Storage DS3500 Storage Subsystem offerings and functionality. These products consists of different models of storage subsystems which provide for a variety of different environments to meet various user needs. This edition applies to the IBM System Storage DS5100 or DS5300 Storage Subsystem with controller firmware version 7.30, and to all subsequent releases and modifications until otherwise indicated in new editions.
If you have experience with IBM DS serial storage systems(previously called FastT), then probably you familar with GUI based Storage Manager.
Do you know that you can also use Command line interface and the script commands for DS3000, DS4000™, and DS5000 Storage Manager software to configure, operate, and maintain a storage subsystem ?
Here I show some most useful command examples, for more detail, you can check the a reference book called 'Command Line Interface and Script Commands Programming Guide', describes all the commands.
Suppose you have your hardware installed and controller ips configured.

In case you are interested, I have another article shows the script to Using command line interface to setup DCS3700 and DCS3860
There are also some commands you can delete, destroy logical drives, fail physical drives. To be safe, I don't list them here, please refer the SMcli command line reference, or consult your vendor support.
