11.6.23 Remote Copy states and events This section describes the various states of a MM/GM relationship and the conditions that  cause them to change. In Figure 11-94 shows an overview of the status that can apply to a  MM/GM relationship in a connected state. When the MM/GM relationship is created, you can specify whether the auxiliary volume is in  sync with the master volume, and the background copy process is then skipped. This  capability is useful when MM/GM relationships are established for volumes that were created  with the format option. The following step identifiers are shown in Figure 11-94: Figure 11-94 Metro Mirror or Global Mirror mapping state diagram GLYPH<SM590000> Step 1: a. The MM/GM relationship is created with the  -sync  option, and the MM/GM relationship  enters the  ConsistentStopped  state. b. The MM/GM relationship is created without specifying that the master and auxiliary  volumes are in sync, and the MM/GM relationship enters the  InconsistentStopped state. GLYPH<SM590000> Step 2: a. When an MM/GM relationship is started in the  ConsistentStopped  state, the MM/GM  relationship enters the  ConsistentSynchronized  state. Therefore, no updates (write  I/O) were performed on the master volume while in the  ConsistentStopped  state.  Otherwise, the  -force  option must be specified, and the MM/GM relationship then  enters the  InconsistentCopying  state while the background copy is started. b. When an MM/GM relationship is started in the  InconsistentStopped  state, the MM/GM  relationship enters the  InconsistentCopying  state while the background copy is  started.  Chapter 11.
