14.4 DS Command-Line Interface
Although the DS CLI will not run on a System z processor, it can be used to perform
operations on mainframe disks if you have a supported server environment (for example,
Windows XP). The DS CLI can be used to create scripts for setup and control of DS6000
functions. It is a flexible and powerful interface. The DS CLI commands are documented in
IBM System Storage DS6000: Command-Line Interface User´s Guide, GC26-7922.

14.5 DS CLI command- examples
In this section we cover the most frequently used DS CLI commands in a Metro Mirror
environment, and provide examples of their usage. For most of these commands, you must
know some (or all) of the following information:
򐂰 The serial number and device type of the source and target DS6000, identified by the -dev
and -remotedev parameters.
One way to get the serial number and device type is to use the lssi command.
The serial number and device type will have the format IBM.1750-1300247, for
example.
򐂰 The WWNN of the remote DS6000, identified by the -remotewwnn parameter. The WWNN
is also available using the lssi command.
򐂰 The LSS numbers where the source and target volumes are.
–The lslss command displays all of the LSSs on the system.
For a particular volume, the first two digits of the volume number represents the LSS.
For example, volume D000 is located in LSS D0.
LSS numbers are two-digit hexadecimal numbers.
Note: In order to run the job to refresh the VTOC of the secondary volume, the Metro
Mirror volume pair must first be deleted.
Note: Many of the examples that are presented here omit the -dev and -remotedev
parameters because we specify them in the DS CLI profile. Using the profile can
save a significant amount of typing.
