Our weekly secondary AuxCopy is stuck at 30% since this weekend (so that it is blocking all the primary disk to disk incremental copies), with the below 2 error messages

 

Thinking it might be some ports communication issue between the Media Server (S01190) where the tape library is attached to, and the CommCell Server (S02116), so I did the below ports check between the 2 Servers:

 

Telnet from the Media Server (S01190) to the CommCell Server (S02116)

Port 8400        OK

Port 8401        OK

Port 8403        OK

 

Telnet from the CommCell Server (S02116) to the Media Server (S01190)

Port 8400        OK

Port 8401        Not OK

Port 8403        Not OK

 

Now, before I speak to our Network/Security administrator who have recently installed SentinelOne AV on both of the above 2 Servers, I’m wondering if I’m heading the right direction, and if I have done all the ports checking ? 

 

Thanks,

Kelvin

That definitely puts a potential spin on it….

Let me ask a few questions:

The Aux Copy, where is the data going from and to?  Meaning which 2 Media Agents?

The backups are all running to which of the Media Agents?

I see 2 machines referenced and want to be sure I know which is which:

  • S01190 - Media Agent with Primary jobs running to it just fine.  It looks like this MA is the proxy for the VMs and I assume the MA for the library as well, so there’s no actual transfer of data between servers, which COULD be why….
  • S02116 - Commserve (check readiness failed here),  is this also a Media Agent? is it involved in the Aux Copy?

It is possible that different executables are being blocked, but that’s unlikely a cause….it’s all the same directory.

I’m going to loop in a colleague and see if they can see if I’m missing anything.  Still confident it is the AV, but want the whole picture to make sense :nerd:

 

Thanks ! I’ve passed the message to my colleague who will look into this tomorrow.

However, there is another thing though, i.e. whereas the AuxCopy is failing, its Primary Copy is running fine on this same S01190 Media Serve (see below) - how come is this possible ?

 

OK, I’ll speak to our Network Security administrator about that. In the meanwhile, could I ask you to give me a link which shows how to set Commvault exclusion in AV ?

 

Very much appreciated,

Kelvin 

 

Hi Mike,

 

Just ran Readiness on both of the Servers, which seems to be OK

 

 

But it failed the below 2 commands on both Servers

  1. CvNetworkTestTool -Client -SrvHostName S02116 (ran on the Media Server S01190)
  2. CvNetworkTestTool -Client -SrvHostName S01190 (ran on the CommServe S02116)

with the below error messages

 

Do we know exactly what ports are being blocked between the two ?

 

Thanks,

 

Kelvin

PS. Pls ignore the offlined tape library “Quantum Scalar i40-i80” as it’s been replaced by “Quantum Scalar i40-i80 21”, although the offlined is still set as the default one:
