The Modular Disk Storage Manager (MDSM) software that is used to manage the Dell PowerVault MD3000 and MD3000i storage arrays is a powerful GUI for creating disk groups, configuring hosts, and setting up iSCSI parameters. It has a scripting component, the storage management command line interface (SMCLI) that enables the user to script actions that become tedious and error prone with the GUI, such as disk group/virtual disk creation, and to set parameters (such as disk group element size) that are not exposed through the GUI.

This note will show how to use the SMCLI to script disk group/virtual disk creation.

Get the full MD3000/3000i scripting document from support.dell.com for details (drill down to the MD3000i on support.dell.com and look for user guides).

The smcli program is installed along with the MD3000/3000i Modular Disk Storage Manager controller software
(C:\Program Files (x86)\Dell\MD Storage Manager\client/smcli.exe on our systems)

To automate disk group creation, use the MDSM GUI to create the first disk group on the MD3000i

Then, use SMCLI to store the MD3000i configuration (r3md3000i resolves to the IP address of the management port on the first MD3000i controller):

C:\>smcli r3md3000i -c "save storagearray configuration file=\"c:\\md3000i_config_base.scr\";"

This is what md3000i_config_base.scr looks like:

The result, md3000i_create_LUNs.scr, looks like this:
