A bitmap operation, which is triggered by reaching the threshold specified by the ChangedTracks or DelayTime parameter, was unable to be mirrored to the swap volume.
XRC functions are active.If a HyperSwap® operation occurred, one or more volumes require full resynchronization from the swap volume to the remote volume.
Using information pertaining to the reported return code, determine and perform the actions necessary to restore the ability to mirror bitmap operations. If incremental resynchronization is required by local operations, refrain from using the HyperSwap function if possible until the problem is corrected.
