Restoring pair statuses in the consistency group when the primary volume is at the secondary site

When a GAD pair is suspended due to a failure and the primary volume is at the secondary site, you can restore pair statuses in the consistency group after recovering from the failure.

1. Resynchronize a suspended pair.

   When the I/O mode of the primary volume is Local, resynchronize the pair by specifying the primary volume.

   Command example:

    pairresync -g oraHA -d dev0 -IH1

2. At the primary site, swap suspend the pair by specifying a consistency group.

   Command example:

   pairsplit -g oraHA -RS -IH0

3. At the primary site, swap resynchronize the pair by specifying a consistency group.

   Command example:

   pairresync -g oraHA -swaps -IH0

4. At the secondary site, swap suspend the pair by specifying a consistency group.

   Command example:

   pairsplit -g oraHA -RS -IH1

5. At the secondary site, swap resynchronize the pair by specifying a consistency group.

   Command example:

   pairresync -g oraHA -swaps -IH1

• Restoring pair statuses when a GAD consistency group contains local I/O mode pairs and block I/O mode pairs

  When a GAD pair is suspended due to a failure, if a GAD consistency group contains pairs whose volumes are in Local I/O mode and pairs in Block I/O mode, you can restore pair statuses in the consistency group after recovering from the failure.
