Legend:
resync: Indicates that the copy pair can be re-synchronized.
restore: Indicates that the copy pair can be re-synchronized in reverse (from the secondary volume to
the primary volume).
create: Indicates that a copy pair can be created.
delete: Indicates that the copy pair can be dissolved.
split: Indicates that the copy pair can be split.
--: Indicates that the copy pair status cannot be changed.
*: This is the copy pair state when a 3DC multi-target configuration is used.
TIP:
Notes about pair status transitions:
• If a selected copy group includes a copy pair whose copy pair state is Error (PSUE) or Error
in LUSE , the state of all copy pairs is assumed to be Error (PSUE) .
• If a selected copy group includes copy pairs whose copy pair states differ, all copy pair statuses
to which each copy pair can be changed are displayed as candidates. However, note that nothing
is displayed if a copy pair whose pair status cannot be changed is included (and pair statuses
cannot be changed on a copy group basis).
