Deleting a PPRC volume pair

Issue the CDELPAIR command to delete PPRC primary and secondary volumes. Direct the command to the primary device.

Before issuing a CDELPAIR command, verify that the necessary paths are active between the primary and secondary volume pair. If all of the paths that were established between both of the storage controls have been disabled, the CDELPAIR command will fail. PPRC may issue the following two messages:

   ANTP0122I PRIMARY CU TIMED OUT ATTEMPTING TO COMMUNICATE
             WITH SECONDARY
   ANTP0001I CDELPAIR COMMAND UNSUCCESSFUL FOR DEVICE nnnn.
             COMPLETION CODE: 08

After the CDELPAIR command times out, the state of the primary volume is simplex. The secondary volume remains in its previous state (duplex, pending, or suspended). You then need to issue a CRECOVER command to return the secondary volume to the simplex state.

The following command deletes a PPRC volume pair:

CDELPAIR DEVN(X'0F40') PRIM(X'6060' 62019 X'00')
              SEC(X'6061' 68006 X'09')

You can process the following TSO CLIST in a standard TSO environment.

Example: This example shows how to use a CLIST to delete a volume pair.

     CONTROL PROMPT
     CDELPAIR                               +
        DEVN(X'04C6')                       +
        PRIM(X'6060' 62019 X'06')           +
        SEC(X'6061' 68006 X'09')
     ENDDATA

Start of change If you remove a pair that is part of a multi-target configuration, the microcode also automatically removes the MTIR relationship between the secondaries. End of change
