How pair status changes
The primary system changes and maintains the status of the P-VOL and is responsible for keeping
the P-VOL and its S-VOL synchronized. The secondary system maintains the status of the S-VOL.
• The primary system can change the status of the P-VOL and S-VOL.
• The secondary system can change the status of the S-VOL but not the P-VOL. When an operation
is performed from the secondary system, the primary system detects a status change in the
S-VOL and then changes P-VOL status accordingly.
• The status indicates the state of the volume or pair:
When a pair is started, the secondary system changes the status of the P-VOL and S-VOL
to Pending. When the initial copy operation is complete, the primary system changes the
status of both volumes to Duplex.
◦
◦ When you split a pair, the system changes the status of the P-VOL and S-VOL to Suspended.
◦ When a pair is suspended due to an error condition, the primary/secondary system
changes the P-VOL and S-VOL status to Suspended.
