Where you noticed the Interface names are different? I assume you are looking at the replication property page - Please check which field you are looking at.

I understand you are getting confused with the term "Data Mover Interconnect" - this is not the same as the Interface name used by a CIFS server on a VDM which needs to be the same on both source and destination for CIFS replication to work properly.

The Data Mover interconnects are are the interfaces configured for the Replication traffic only - i.e. all the replication data will use the interconnect mentioned on the source and destination. This is not used by the CIFS server.

If you look at the replication property - you see the data mover interconnect names used for carrying the replication traffic - not the interface names used by the CIFS server. Please open the Online Help page which will provide you more details on the replication page.

In order to CIFS failover work properly - you need to ensure that the Same Interface NAME is created on the destination side - on the same data mover using same network configuration.

Hope I am able to clarify your doubt - if not, please feel free to revert back.

Thank you for the reply

I do not have a separate datamover interconnect interface for replication traffic only.

Both my replication traffic and my cifs traffic use the same interface on the source, in this scenario am i still required to have the same interface name on the source and destination?

I checked the VDM properties page on the source and destination and that is the interface i am referring to.

it is different on the destination so i need to change it to match the source correct?

below is the text i copied from the Celerra v2 replication pdf on powerlink:

The source and destination side interface names must be the same for CIFS

servers transition. You may need to change the interface name created using

Celerra Manager (by default it uses IP address) by creating a new interface

name with the server_ifconfig command.

page 82 v5.6.47

Can you list the Interfaces on both Source and Destination NAS - with their name and IP Address. Also - please provide the CIFS server details with the CIFS server name and associated Interface.

You are right - in order to CIFS failover to occur properly - the Interface Name MUST BE THE SAME on both Source and Destination NAS. If the interface names on the sites are not identical, you will not be able to load the VDM on the destination Data Mover after a failover.

The name of the Interface on the destination can be changed to match the name on source side - but I suspect this will disrupt the replication session and you may have to setup the replication with correct name.

I'll suggest to open a case with Tech Support team and allow them to check the configuration on both the NAS boxes and suggest you accordingly.

I am working on replicating cifs between 2 NX4 and I have 3 questions:

1/ for replication and usermapper do I need to dedicate an interface or can I use the same for cifs ?

2/ When I create the target VMD do I need to set to mounted or this will be automatically be set during the replication ?

3/ When I create the cifs file system on target do I need to set it to read-only (required for iSCSI lun)  ? unlike iSCSI lun I don't have this option for cifs file system?

1) No

2) Don’t know offhand – should be in the manual – or use the wizard which will do the right thing automatically

3) No

thank you,.

1) you do not need to have dedicated interfaces

for simplicity, do not create the target vdm or filesystem. Use the GUI Wizard and let the Celerra create the target objects ...

the target vdm must be monted state and the target file system will be samme size as source and mounted on vdm as read-only.

what about the cifs server on target ? do I need to create it ( cannot on a vdm monted) or the failover process will reate it and add join it in DC.

I work with replicator v2 on unissphere.

The cifs server on the target will come from the replication of the VDM

Make sure there is an interface on the target with the same name as the one being used by the source cifs server
