If your configuration consists of more than three nodes, the mirrors must be deletedand recreated.Refer to the examples below.See "WAN Considerations" and "Initial Synchronization of Data Across the LAN/WAN" in the "Configuration”section.This is the system that has the new source IP address available for the mirror.The drive letter of the mirror to be changed.The previous IP address of the target system.The new IP address of the source system.The new IP address of the target system.Notes:• A job may contain multiple volumes and multiple mirrors. The CHANGEMIRRORENDPOINTS commandwill modify endpoints on one mirror each time it is used. For a 1x1 mirror (1 source, 1 target), onlyone command is required. For a 2x1 mirror (2 nodes with a shared volume with one target node) or a1x1x1 (1 source, two target nodes), two commands are required to change the necessary mirror endpoints.• If an existing mirror whose endpoints are being changed is currently an active mirror, it must be put intothe Paused, Broken or Resync Pending state before the endpoints can be changed.CAUTION: Using the Break command will cause a full resync. It is recommendedthat the mirror be Paused instead.DataKeeper for Windows Technical DocumentationPage 64
