Pause and UnlockPause and UnlockThis command pauses the mirror and unlocks the volume on the target system. You may wish to unlock thetarget volume in order to make a backup of the volume.Warning: Any writes to the target volume while it is unlocked will be lost when the mirror is continued. Also, ifa reboot or shutdown is performed on the target system while a volume is unlocked, a full resync will occurwhen the mirror is continued. To prevent the full resync in this case, be sure to perform a "Continue andLock" prior to rebooting or shutting down the target system.Note: If replacing the target volume, either break the mirror or delete the mirror in order to ensure a full resyncof the data from the source volume to the new target volume when the new target volume is in place. SeeReplacing a Target for further information.The Continue and Lock command will relock the target volume, perform a partial resync (or full resync if thetarget has been rebooted or shut down while unlocked) and resume the mirroring process.1.
