Non-Disaster Tolerant Data Movement to an Alternate Site

Procedure

If the data being moved is in a non-disaster tolerant environment, then it can be moved with fewer steps

than when it has to be protected from loss. This method can be used to move data to another site in a

non-disaster tolerant environment. Refer to Figure 11. This procedure is used for Data Distribution,

Data Migration, and Data Mining.

1 Enable access from the target controller to the initiator LUN being moved.

2 Create a new target LUN with access to the initiator controller.

3 Create a remote copy set from the initiator and target LUNs and allow normalization to occur.

4 Delete the remote copy set from the initiator and target LUNs.

Example

In this example, assume that both subsystems are running identical ACS 8.xP and that the connections

have been named. The first two commands are issued to show the initial conditions.

I 1. Issue this command to show all units configured to the initiator controller:

SHOW UNITS

Example Display 20 shows a sample output of this command.
