Initiator and Target Site Movement
Procedure
This procedure demonstrates how to move an initiator and a target site to different site locations. Refer
to Figure 14. This procedure is used for Data Migration.
1 Stop host access to the fabric.
2 Delete the remote copy sets between the initiator and target sites.
3 Create connections between the BuildngC (the new target site) and BuildngB (the old target site).
4 Create LUNs at BuildngC (the new target site) that match the old target LUNs.
5 Create connections between BuildngB (the old target site) and BuildngC (the new target site).
6 Remove access to the old initiator LUNs.
7 Create a remote copy set between BuildngB (the new initiator) and BuildngC (the new target site).
8 Allow host access to the BuildngC (new target site) LUNs.
