Hitachi Universal Replicator (TM) for Mainframe User Guide: HP XP24000 Disk Array, HP XP20000 Disk Array (T5278-96044, May 2011)

The emulation type of command devices and remote command devices must be OPEN-V. For
details on remote command devices, see the HP StorageWorks XP24000/XP20000 External
Storage Software User's Guide.
CAUTION: Performing maintenance operations on remote command devices (for example, devices
A and B in Figure 16 (page 68)) used for connections between secondary storage systems will
cause the pairs to be suspended as if there was a failure. To avoid this, before performing
maintenance tasks, remove all journal groups in the extended consistency group that use the remote
command devices under maintenance.
