VCB failures with EMC Networker

I was able to get VCB working at one point with VC 2.0 and EMC Notworker 7.3.x, but with VC 2.5 and Notworker 7.4.2, I cannot. I consistently receive the following errors:

The virtual machine identified by <vm name> is unknown.
Exit Code: 16

So far, EMC support has been less than helpful, suggesting that I need to call VMWare. Has anyone else seen this problem?

Try a query with the vcbVmName utility to make sure the name didn't actually change. Also, you can set LOGFILE=6 in config.js to get a verbose log. I would also upgrade to VCB 1.5 which was just released last Friday.

The vcbVmName command indicates that the VM is named what I think it's named. Where would the logfile go and what might it be named?

They will be located in %TEMP% and are named vmware-vmount*.log and vmware-vlun*.log. %TEMP% is usually C:\WINDOWS\TEMP unless you changed it.

I'm feeling the same pain bud,

Like you I used the VCB command to get the names to be accurate about the name (case and spelling etc) but it didn't help. The other method I try was using the IP address of the VM instead of the name for the client which I would have thought worked but it didn't.

The verbose logging for me was displayed only in the command prompt from where I executed the VCB mount command, that revealed that VCB didn't have a problem but Legato always returned 'what vm' and I can't think what else to try. So it must be something with Legato Networker, I was going to try and log a call with them instead.

You can try running the vcbMounter command directly to rule out VCB.

VcbMounter works, although I note what may be a problem: using name based access, the VM name is upper case, but Networker forces its client names to lower case, and the command is case-sensitive. If I use the ipaddr search directive with the VM hostname, that works fine, so it's clearly possible to mount the VM.

OK, now you're getting somewhere. Yes, everything is case sensitive with VCB. You should be able to use hard IP addresses or FQDNs to perform your backups. You may be able to set your config.js with VM_LOOKUP_METHOD="ipaddr";
I've never used Networker with VCB, but the underlying scripts are the same for all.

Right--as far as I can tell, VCB is configured correctly to use the ipaddr directive, which is why I'm thinking it's a matter of how the Networker module is talking to VMWare.

Maybe there is a glue.js that calls the VM name instead of the ipaddr??

Has EMC gotten back to you at all? I've been working with them to try to sort this out, but with no luck so far. The only thing I can think of is that VMWare is now using an SSL certificate in VC 2.5, which may make Networker unhappy.

One other thing...you mentioned that you upgraded. In config.js, change the port to 443. 902 does not work now.

Well, that was certainly part of it. Thank you very much for the info! I've moved on to the following output:

savegrp: suppressed 55 lines of output.

  • A certificate in the host's chain is based on an untrusted root.

I'm going to guess that this is related to permissions for the VCB service account, which currently has the VCB Proxy User role assigned to it for the entire data center. Are there other permissions I should be looking at?

I answered this question myself and changed the service account from the VCB Proxy User role to VMware Consolidated Backup User role, and that seems to be working. I am waiting to see how this turns out, but I'm feeling very optimistic!

Newest error is:

Version mismatch:
Exit Code: 10

Guessing that the solution is to remove VCB and/or the Notworker integration module and reinstall.
