Breaking a mirror is similar to the Pause and Unlock function. It suspends mirror operation and unlocks the target volume for read/write access. The difference is that the Break operation marks all bits in the DataKeeper Intent Log as dirty, which forces a full resync to occur when the mirror is resync’ed to resume mirroring.
Warning: Do not write to the target volume while the mirror is broken. Any writes to the target while the mirror is broken will be lost when the mirror is resynchronized.
- Select the job that contains the mirror you want to break.
- Right-click on the job selection and choose Break All Mirrors or select Break All Mirrors from the Actions task pane.
- Select Yes to break all mirrors in the selected job.
- The mirror state will change to Broken in the Mirror Summary window.
Note: The Resync command will relock the Target volume, perform a full resync and resume the mirroring process.
