# Clone copy session options

Clone copy sessions enable you to create clone copies of a source volume or storage group on multiple targets.

The following table describes the TimeFinder/Clone session options:

Table 1. TimeFinder/Clone session options
Session option | Description | Available with action
--- | --- | ---
Both Sides | Activates all locally and remotely associated clone pairs in an SRDF group. | Activate Establish
Concurrent | This option performs the action for an additional clone pair in a group. | Create Recreate Establish Activate Verify
Consistent | This option creates clone copies that are consistent with the database up to the point in time that the activation occurs. It suspends writes to the source volumes during the activation. | Activate
Copy | This option is not supported on storage systems runningPowerMaxOS 10 (6079). The option creates a full data copy. By omitting this option (default), the volume pair state is in the CopyOnAccess state when activated. Copying of the data is deferred until either tracks on the source volume are written to, or tracks on the target volume are read or written. This option is only applicable when the target volume is a regular volume (not a virtual volume). | Create Establish
Differential | Used with either the Copy or Precopy option to create an SDDF session for maintaining changed track information. It must be used when creating copy sessions on which you plan on issuing a Restore action. | Create Establish
Force | Overrides any restrictions and forces the operation, even though one or more paired volumes may not be in the expected state. Use caution when checking this option because improper use may result in data loss. | Create Establish Activate Restore Split Terminate
Not Ready | This option sets the target volumes as Not Ready. | Establish Activate Restore
Optimize | Optimizes volume pairings across the local storage system without regard for whether the volumes belong to different SRDF (RA) groups. For remote volumes, use the Optimize Rag option. | Create Establish
Optimize Rag | Uses optimization rules to create remote BCV pairs from volumes within the same SRDF (RA) group on a storage system. | Create Establish
Precopy | Copies the tracks in the background before the clone session is activated. Used with the create and recreate actions. | Create Recreate
Restored | With the verify command, verifies that the copy sessions are in the Restored state. With the terminate command, terminates a restored VP Snap session. | Verify Terminate
Star | This option targets the action at volumes in SRDF/Star mode. | Create Recreate Establish Activate Restore Split Terminate
Symforce | Forces an operation on the volume pair including pairs that would be rejected. Use caution when checking this option because improper use may result in data loss. | Terminate
