5.2.5 Metro Mirror setup

In this scenario we will set up an SVC based Metro Mirror Failover/Failback session with a

single volume pair as can be seen in Figure 5-41 on page 109.

As a review, Metro Mirror (MM) is a synchronous data replication mechanism and was

previously called Peer-to-Peer Remote copy or PPRC. I/O completion is signaled when the

data is secured on both the local storage server and the remote storage server. Metro Mirror

is popular for two site disaster recovery solutions. Metro mirror is available in any combination

between DS6000, DS8000 and ESS800. Synchronous data replication is also available on

the DS4000™ family and with the SVC, but again not directly compatible with Metro Mirror on

the DS6000, DS8000 and ESS 800.

Figure 5-41 SVC based Metro Mirror setup

Use CSMCLI to manage Metro Mirror session

In this instance we will create a session, add the copy sets and list the session attributes as

part of a single script.

As we can see in Figure 5-42, the script file contains multiple commands to setup the session

and the volume pairs as part of the copy set. In this case we have pre-determined the volume

pairs and captured these as part of the mkcpset command. We have also specified that the

Metro Mirror session type is mmsd or Metro Mirror Single Direction.

Invocation of this script results in the output as shown in Example 5-2.
