The snapmirror baseload was done using multi IP, after that, the snapmirror relation was updated and multi IP was not used anymore.
After updating the snapmirror.conf file and put back on the snapmirror relation the multi IP I didn't receive anymore these kind of alert.
snapmirror.conf - Before:
filerA:vol_Test filerA_DR:vol_Test - 30 10,12,14,16,18,20,22 * *
snapmirror.conf - After:
filerA-FilerA_DR = multi(192.168.23.11,192.168.23.15)
filerA-FilerA_DR:vol_Test filerA_DR:vol_Test - 30 10,12,14,16,18,20,22 * *
