2. You will be prompted to confirm the role change. Select OK to confirm (Figure 5-20).Figure 5-20 Roll change confirmationOnce you have confirmed, the role is changed to slave, as shown in Figure 5-21.Figure 5-21 New role as slave volume3. Repeat steps 1–2 for all the volumes that must be changed.Role changeover at the primary site using the XCLIWe now change roles for the master volumes at the primary site with the XCLI and makethem slave volumes. Before doing this, ensure that the original production server is shutdown.1. On the primary XIV open an XCLI session and run the mirror_change_role command(Example 5-9).Example 5-9 Change master volumes to slave volumes on the primary XIV>> mirror_change_role vol=itso_win2008_vol2Warning: ARE_YOU_SURE_YOU_WANT_TO_CHANGE_THE_PEER_ROLE_TO_SLAVE Y/N: YCommand executed successfully.Example 5-10 List mirror couplings2.
