Hello to all,

I have a problem when a job is running Backup to tape job ( the lastest full backup job) during the job it says this error : And the XXXBK1 computer physical lost the network.

The RPC server is unavailable RPC function call failed. Function name: [InvokerTestConnection]. Target machine: [IP adress].
Backup Job 8Error18:15:1722:30:26438,6 GB438,6 GB435,5 GB4:15:09Tape server XXXBK1 is unavailable [XXX1BK1] [TapeService] Failed to Get media info Tape server XXXBK1 is unavailable [XXXBK1] [TapeService] Failed to connect to tape service on 'IP adress:6166' [XXXBK1] Failed to open management RPC connection to proxy service. Port: '6166'. The RPC server is unavailable RPC function call failed. Function name: [InvokerTestConnection]. Target machine: [IPadress].

Veeam Backup & Replication 9.0.0.1715

My library PV124T is a harware connected directly to a windows server 2008 R2 named XXX1BK1.

XXX1BK1 lost the netwotk. can'p ping nothing. TO fixe i have to disable en enable the Network Adapters . it is a Broadcom's NetXtreme II 1 Gigabit Ethernet controllers: 5706, 5708, 5709, 5716.
I have also updated the drivers V 2014 on http://driverdownloads.qlogic.com/QLogi ... 245&Os=190

A case is opened on VEEAM Case # 01918137 - backup to tape

I don't know what to do .

DO you have any idea's ?

Thanks.
Cheers/

Hi Nicolas,

To be honest, it has been a while since looking at 2008 R2 ;-) but I do remember from a few years ago there were many issues with Broadcom controllers when TCP Chimney Offload was enabled. The only fix at that time (again, some time ago) was to disable a few of those offloading techniques and then everything worked again.

Maybe try to do this and see what it does? The command to do this is

Code: Select all
netsh int tcp set global chimney=disabled


This will however turn it off for the entire server (you can do it in the properties per network adapter also...)

To turn it back on again (if that doesn't solve it)

Code: Select all
netsh int tcp set global chimney=enabled


And if you just want to check the status it is
Code: Select all
netsh int tcp show global

Querying active state...

I'm not sure to be honest... It might disrupt the network and I don't know how the OS will react to that... I think it is best to do this if there is no job running

I can try to change to disable even if Offload State " Inhost" is used .. as the result of the command
..
netstat –t
You receive output that resembles the following:
Code: Select all
