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 1-37 shows the relations between the migration volume
statuses and command acceptances. 
Table 1-37: Command Issues and Pairing Status Transition
•
• Accepted: A command is accepted and executed. When the command
execution succeeds, the status changes to that of the shown number.
• Acceptable: No operation is executed, though a command is accepted.
• Shaded portions: Command execution is rejected and the operation
terminates abnormally.
