This section contains commands that create, manage, and delete Remote Mirror and Copy (formerly PPRC) pairs and display Remote Mirror and Copy pair information.
The failbackpprc command copies the required data from the source volume to the target volume in order to resume mirroring. You can use this command after a failoverpprc command has been issued to restart mirroring from site A (local site) to site B (remote site).
The lspprc command generates a report that displays a list of remote mirror and copy volume relationships for a storage image and the status information for each remote mirror and copy volume relationship in the list.
The mkpprc command establishes a remote mirror and copy relationship for a volume pair.
The freezepprc command creates a new remote mirror and copy consistency group. It places the source logical subsystem (LSS) in the long busy state so that no I/O can be directed to it. It also removes remote mirror and copy paths between the source LSS and target LSS and sets the queue-full condition for the primary volume.
The pausepprc command pauses an existing remote mirror and copy volume pair relationship or pauses a single volume ID.
The resumepprc command resumes a remote mirror and copy relationship for a volume pair.
The rmpprc command removes one or more specified remote mirror and copy volume pair relationships, or it removes a single volume ID (which might be useful when a disaster occurs and you want to specify only the available volume and not both the primary and secondary volumes).
The unfreezepprc command resumes I/O activity on a storage unit where the freezepprc command has been issued. The unfreezepprc command resets the queue full condition for the primary volume.
