Managing Metro Mirror Pairs With The Ds Cli - IBM System storage DS6000 Series Redbook

Figure 29-17 Managing Metro Mirror pairs
29.4.2 Managing Metro Mirror pairs
In this example, we show how you can establish Metro Mirror volume pairs between a
DS6000 and an ESS 800 with the DS CLI. We created two Metro Mirror pairs. Volumes 0600
and 0601 from the DS6000 are the source volumes, and the target volumes on the ESS are
0500 and 0501.
Example 29-11, we created the pairs with the mkpprc command. We then listed them with the
lspprc command and removed one pair with the rmpprc command.

withdrawn.
We connected to the DS6000 SMC using DS CLI, so the ESS 800 is the remote device. To
establish pairs where the ESS 800 is the source device, you must connect to the ESS 800
using the DS CLI. This will make the DS6000 the remote device.
Important: If you specify the wrong -remotedev or you are using a profile with a remote
device specified that is different from the one you intended to work on, you might get an
error message, CMUN03057, that says that you are specifying an invalid subsystem ID.
This might be because you are specifying the wrong remote device serial number. If you
have multiple potential remote devices, do not specify a remotedev in your DS CLI profile.
