Migrating backup / DR traffic from one interface to another

Hello all

My client's controllers are using a single interface for all activity and now would like to move their backups and mirrors on a "private" network.

If we create this private network, everything pings and connectivity is good, how can i get protection manager to change freeway lanes?

My thoughts would be like this:

1.     Make sure on each controller has proper host table entries so that filers can ping those backup interfaces.

2.     Suspend all activity in Protection Manager ( this way all current relationships stay in tact )

There is no way in Protection Manager to choose a controller's interface, do I have to ...

1.     remove all relationships

2.     perform a manual resync and update

3.     import those relationships back into PM

Would this avoid re-baselining?

Re: Migrating backup / DR traffic from one interface to another

HI Emanuel,

     For QSM and VSM to use specific interface set the following options.

[root@lnx ~]# dfm host set
Valid options are
  hostLogin                 Login
  hostPassword              Password
  hostLoginProtocol         Login Protocol
  hostPreferredAddr1        Preferred IP address 1
  hostPreferredAddr2        Preferred IP address 2

Set this for the source filer  and similarly for the destination filer also.

dfm host set <filername-or-id>  hostPreferredAddr1= x.x.x.x

For SV relationships use the filer options.

ndmpd.preferred_interface    disable

to an interface name like e0b or e0c.

Below is the FAQ on the same.

Even though this talks about backup manager this is applicable to PM created SV relationships too.
