You must resynchronize a pair by specifying the I/O preference mode when remote path failed option if you change this setting for an existing pair. For information about I/O preference mode when remote path failed, see I/O preference mode when remote path failed in a GAD pair.

If you want to change the I/O preference mode when remote path failed for a GAD pair in a consistency group, the same I/O preference mode when remote path failed must be set for all existing pairs in the consistency group.

Use the CCI pairresync command with the -pr pvol or -pr disable option when resynchronizing a pair for which I/O preference mode when remote path failed is switched.
When resynchronizing a pair for which I/O preference mode when remote path failed is switched from Disabled to Primary Volume use the -pr pvol option.
```
pairresync -g oraHA -pr pvol -IH0
```
When resynchronizing a pair for which I/O preference mode when remote path failed is switched from Primary Volume to Disabled use the -pr disable option.
```
pairresync -g oraHA -pr disable -IH0
```

Display pair information and check the PR column to ensure that I/O preference mode when remote path failed has been set.
