Field - r7451gsf

Global Mirror Collisions (GMC) sidefile count (short float). A GMC occurs when, during the sending of data in the secondary to create a consistency group, a subsequent host update is attempted before the modified track has been transmitted to the secondary volume. The modified track will be moved to the sidefile before allowing a new host write. The counter will be incremented by one when a track is added to the sidefile.
