(We discuss asynchronousmirroring in Chapter 6, “Asynchronous Remote Mirroring” on page 149.)– Master CG / VolumeThis is the volume or consistency group at the local site to be mirrored. You can selectthe volume or consistency groups from a list. The consistency groups are shown inbold and they are at the end of the list.– Target SystemThis is the XIV at the remote site that will contain the slave volumes. You can select thetarget system from a list of known targets.– Create slaveIf you have not yet created target volumes at the remote XIV, you can check mark theCreate Slave option. In this case you also must select the storage pool where thevolume must be created at the target XIV. This pool must already exit at the target XIV.The remote XIV will automatically create a target volume of the same size as thesource volume.If selected, the slave volume will be created automatically. If left unselected you mustcreate the volume manually.If you specified a consistency group instead of a volume this option is not available. Aslave consistency group must already exist at the remote site.– Slave PoolThis is the storage pool on the XIV at the remote site that will contain the mirrored slavevolumes. This pool must already exit. This option is only available if you check markedthe Create Slave option.Chapter 5. Synchronous Remote Mirroring 127
