Relations between "cc" command issues and status
The migration volumes can be handled by issuing the CCI commands (pair
creation and pair splitting commands). The validity of the specified operation
is checked according to the status of the paired volume (primary volume).
Table 6-12 Command issues and pairing status transition on page 6-42
shows the relations between the migration volume statuses and command
acceptances.
