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: 

CBR3726I FUNCTION INCOMPATIBLE ERROR CODE 32 FROM LIBRARY XXX  FOR VOLUME xxxxxx . 

X'32' There is more than one valid copy of the specified export list volume in the TS7700 grid configuration. 

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. 

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: 

GLYPH<SM590000> Define an MC, for example, MCCEDATA, on Cluster 1: 

<img src='content_image/999081.jpg'>

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: 

<img src='content_image/999082.jpg'>

GLYPH<SM590000> Define this MC on Cluster 0: 

<img src='content_image/999083.jpg'>

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.
