cloning with data domain boost over fibre channel
I have a DD2500, DDOS 5.4 and Networker Linux 8.1. I created a boost device over IP and a boost device
over fibre channel. Both mount the same volume. I want to clone to a LTO6 fibre channel device. Networker
seems to read only from the boost IP device. Only if I unmount the boost IP device it reads from the boost fibre
device. But this blocks my backups.
How can I force Networker to read always from the boost fibre device.
regards
Bernd

Are they in the same pool? If yes, there seems to preference to use IP always and therefore you would need to have two pools.
You didn't say if your source ssid in on IP or FC. It is possible that IP based original will prefer IP based target and other way around (I also have to disclaimer myself by saying that I don't know if DD based replication will work between these two even they are both DD Boost devices - perhaps in such case data path will go over storage node if integration is not full, but I never tested it).

Hallo Hrvoje,
backup is always done to the IP device since clients are not in the SAN.
The same volume is mounted on 2 devices (IP and FC). With boost and NW 8.1
this is possible. But always the IP device is used.
There seems to be a preference for IP. You are right, could be the origin of the save sets
the rules the selection of the read device.

this can be done but you will need a storage node for all the DDBoost over FC devices.
After you have your new storage node configured, set up all the DD Boost over FC devices on that storage node. Mount the existing volumes to the new FC devices.
In the clone menu, you'll need to enable diagnostic mode and you'll be able to select a storage node to READ from during cloning. Select the storage node we just configured and now all cloning jobs will read from the FC devices.
