Backup VADP in error

Hello everybody,

Since yesterday where i have upgrading Networker from 8.1.0.1 to 8.1.1.2. Some VM in my VADP groups are failed.

The error is :

3065:nsrvadp_save: The following internal error occurred: An error was returned from nsrvddk.exe: Error opening disk, [SDMirrored_LN_BECHU-INT-0001_PERF000_001] MSCS-BECHU-0073/MSCS-BECHU-0073.vmdk: VDDK Error: NBD_ERR_NETWORK_CONNECT

Other VM in the same group and on the same LUN works fine.

I have try to clean mnt folder on Proxy, clean snapshot on vSphere client, enable/disable CBT, switch on/off the Quiesce snapshot.

Same result.

I have all server in W2k8 with NMC 8.1.1.2 and NWS 8.1.1.2 on a separate server.

2 SN (Networker 8.1.1.2) as VADP Proxy.

Thanks for your help.

David.
