Tip:  If the MC specified for export list volume is defined to have copies on more than  one cluster, the Copy Export fails and the following CBR message is displayed: X'32' There is more than one valid copy of the specified export list volume  in the TS7700 grid configuration.  CBR3726I FUNCTION INCOMPATIBLE ERROR CODE 32 FROM LIBRARY  XXX  FOR VOLUME  xxxxxx .  Consider the following Copy Export example in three-way grid environment: a. A Copy Export with the export list volume EXP000 is started from a host that is  connected to the C0, and the Copy Export runs on the C2.  b. The copy mode of EXP000 must be [N,N,D] or [N,N,R], which indicates that the only  copy of EXP000 is on C2.  c. If Copy Policy Override is activated on the C0 and the Copy Export is started from the  host that is attached to C0, a copy of EXP000 is created on the C0  and  C2.  d. The grid detects that a copy of EXP000 exists on two clusters (C0 and C2) and does  not start the Copy Export.  e. Copy Export fails. GLYPH<SM590000> Define an MC, for example, MCCEDATA, on Cluster 1: GLYPH<SM590000> Define this same MC on Cluster 0 without specifying a secondary pool. GLYPH<SM590000> To ensure that the export list volume is written to Cluster 1 and exists only there, define an  MC, for example, MCELFVOL, on Cluster 1: GLYPH<SM590000> Define this MC on Cluster 0: In the following example, assume that the TS7700 that is to perform the Copy Export  operation is Cluster 1 in two-way grid environment. The pool on that cluster to export is pool  8. You must set up an MC for the data that is to be exported so that it has a copy on Cluster 1  and a secondary copy in pool 8. To ensure that the data is on that cluster and is consistent  with the close of the logical volume, you want to have a copy policy of Rewind Unload (RUN).  You define the following information: Secondary Pool 8 Cluster 0 Copy Policy RUN Cluster 1 Copy Policy RUN Cluster 0 Copy Policy No Copy Cluster 1 Copy Policy RUN Cluster 0 Copy Policy No Copy Cluster 1 Copy Policy RUN A Copy Export operation can be start by using any virtual tape drive in the TS7700 grid  configuration. It does not need to be started on a virtual drive address in the TS7700 that is to  perform the Copy Export operation. The operation is internally routed to the TS7700 that has  the valid copy of the specified export list volume. Operational and completion status is  broadcast to all hosts that are attached to all of the TS7700s in the grid configuration. 744  IBM TS7700 Release 5.0 Guide
