NDMP errors on VNX

[gernthefish]

We've running NDMP backups of several NAS shares off our VNX for several months, but lately we're getting failures. Nothing has changed on either end as far as I know. Here are entries from the activity log:

08/09/2016 13:21:50 ANR4399E NAS file server 10.1.80.55 is reporting NDMP
error number 2: Device 31914208 is in use. (SESSION:
8760, PROCESS: 57)
08/09/2016 13:21:50 ANR8844E Unable to open remote drive DRIVE4 (c32t0l0),

error number 2: Device 31931696 is in use. (SESSION:

Any thoughts? The drives appear to be working fine backing up normal TSM incrementals, but the NDMP backups started sporadically failing. Now they don't work at all.

It looks like a network issue with the NDMP protocol: http://www.ibm.com/support/knowledgecenter/SSGSG7_7.1.3/srv.msgs/ANR4399E.html

Restart the clients and/or check for network connectivity. Since you are using LAN Free, make sue that the LAN Free setup is working correctly.

By the way, if I were you, I would find a way to get out of the NDMP backup scenario. Too much headache and terrible performance regardless of what storage you are using.

Thanks moon-buddy. Good advice. We're going to try rebooting the datamovers tonight. If that doesn't work, we'll look at zoning, etc.

Yep, rebooting the datamovers fixed it.
