Scenario - Three way NDMP backup from Isilon. The Isilon is using an IP pool of x.x.x.x (eg 192.168.1.1 - .4) for NDMP operations The media agent has a primary IP of y.y.y.y (eg 192.168.2.1). I have put a second IP on the media agent that is in the same subnet as the Isilon, eg 192.168.1.250. This second IP is on a different nic from the primary IP. When I do a backup of the Isilon the job fails due to “network communication error”. When I look at the logs the problem seems to be that the nasbackup command is still using the media agents original primary IP and not the new secondary IP.
I have tried setting up DIP/Backup Network pair but the job still fails and the logs show that the media agent primary IP is still being used. Is it possible for the NDMP backup to use a specified ip address for the MediaAgent that is not the primary IP? Based on a bit of digging around in the forum it seems that DIPs are not used for NDMP traffic management since the NDMP server (Isilon) is not really a CommVault client. So if DIP is not the right knob what is? Is it even possilble?
Cheers,
Ron
