10.9 Mixed device environments and migration
The Copy Services commands within the DS CLI are designed to interface with both the
DS6000 and DS8000 series and the ESS 800. They will not work with the ESS F20. The
storage management commands
within the DS CLI also will not work with ESS 800. This
means that customers who currently have a mix of 800s and F20s will have to continue to use
the current ESS CLI, but could consider deploying the DS CLI for certain Copy Services
functions.
To explain in more detail for the ESS 800, there are two families of CLI commands. ESS
storage management CLI commands are used for storage management and configuration.
The ESS Copy Services CLI commands are used to manage and monitor Copy Services
relationships (FlashCopy and Remote Mirror and Copy). Currently both kinds of CLI are
installed by the same setup file. The DS CLI combines both these functions into one library of
commands. Table 10-2 shows which CLI should be used based on which hardware is
installed in a particular environment.

ESS F20 ESS 800 DS6000 and 8000 CLI to use
Installed Not installed Not installed Use ESS CLI only.
Installed Installed Not installed Use ESS CLI for most functions. Consider use
of DS CLI for copy functions on the ESS 800.
Not installed Installed Installed Use DS CLI for all Copy Services. Use a
combination of ESS CLI and DS CLI for
storage management.
Not installed Not installed Installed Use DS CLI only.
Installed Installed Installed Use a combination of ESS CLI and DS CLI.
