SnapMirror over FC dedicated ports

mcarlton4 — Thu, 05 Jun 2025 06:23:41 GMT

I am currently implementing Snapmirror over FC and am having issues replicating the data, the replication works over FC if I add the below setting into the snapmirror.conf file at the destination and change the source name to the connection name I have created.

#Regenerated by registry Tue Jul 3 15:56:30 GMT 2012

CRS_Test = multi(192.168.1.1,192.168.1.3)

CRS_Test:vol_test_cifs SAN-CRS-FAS01:vol_test_cifs_FC_test4 - - - - -

The main issues is that everytime we go to set up a new snapmirror replication it starts to push ot over the ethernet network and not the FC network, I have tried to dedicated the ports through snapmirror.access

Controller 1 - snapmirror.access host=192.168.1.1-ql5a

Controller 2 - snapmirror.access host=192.168.1.3-ql5a

Please correct me if this is wrong

I have made sure that the controllers are added to the snapmirror.allow and hosts files

But I keep getting the error 13102 (could not read from socket), does anyone have any idea how I can setup these controllers up so they only use the FC ports for Snapmirror traffic and that when the customer creates new snapmirror relationships they also use the FC network.

Thanks in advance

When snapmirror.access is set to a host= then the allow file is not used. Only used when access is set to "legacy".

You could also setup failover type with fc as primary and Ethernet as secondary in the source connection
