[Execution Conditions]
To perform state display, the following conditions must be satisfied.
(i) The target MV and RV are paired.
(ii) The target MV or RV has been registered in the volume list.
(iii) The volume list is not being created or updated.
(iv) Specifying a volume of a dynamic disk or a GPT-format partition disk is not allowed (Windows
only).
(v) The iSM dedicated special file is not being created (HP-UX version UNIX only).
(vi) When an LVM volume group or a VxVM disk group is specified, the target volume group or disk
group must be active (UNIX only).
(vii) When specifying the combination of an LVM volume group or a VxVM disk group with a special
file name (logical disk name), you must specify the same number of logical volumes that make up
the volume group or disk group as MV (RV) on the special file name (logical disk name) side.
In this case, Copy is performed in specified sequential order (UNIX only).
The above execution conditions except for (i) are not applicable when conducting a joint operation with
the iSM (replication management).
Figure 4-31 shows execution conditions for displaying the replication state.
