Use the following procedure to recover from a failure at the primary and secondary sites when sharing GAD volumes with UR in a GAD 3DC delta resync (GAD+UR) configuration.

  1. Suspend the UR pair by specifying the S-VOL (swap suspend).
    Command example:
    pairsplit -g oraREMOTE -RS -IH2

    You can resume operations at this point by using the S-VOL at the UR secondary site.



  2. Remove the failure at the primary and secondary sites.
  3. Change the I/O mode of the P-VOL to Local.
    Command example:
    pairsplit -g oraHA -iomd local -IH0
  4. Resynchronize the UR pair by specifying the S-VOL (swap resync).
    Command example:
    pairresync -g oraREMOTE -swaps -IH2
  5. Swap the P-VOL and S-VOL of the UR pair.
    Command example:
    pairresync -g oraREMOTE -swaps -IH0
  6. Resynchronize the GAD pair by specifying the P-VOL.
    Command example:
    pairresync -g oraHA -IH0
