Sorry it's been awhile since I last responded to this, but thank you all
for your comments.
I am doing the maintenance and reorganizing the DB as shown below.
MOVMEDBRM MOVPCY(TAPEMOVES) LOC(TAPMLB01)
STRMNTBRM PRTEXPMED(*NO) PRTVSNRPT(*NO) PRTBKUACT(*NO) PRTRCYRPT(*ALL)
WRKMEDIBRM CTLGRP(DMCTC2D) SLTDATE(*CURRENT)
WRKMEDBRM SORT(*VOL) OUTPUT(*PRINT)
I had been working on implementing new control groups to make them
consistent across all three of my partitions. The existing ones were set up
by a person who is no longer here. As a result of this issue I went ahead
and implemented my new control group and now we no longer need a second
tape... go figure.
