'Process Communication' status when validating vdisk store


I've upgrade a PVS 6.1 environment to PVS 7.1. During the process it became apparent that the Service account password was lost so I changed the service account.


After the upgrade, When attempting to validate the vdisk store I get 'Process Communication' as the returned status. What does this mean?


Also I cannot create a vdisk larger than 1mb as that is the only option presented when attempting to create a new one.


Another issue is that I cant import vDisks, I'm assuming that this is all related.

I have found the issue. 


The customers PVS instance has a separate network for Streaming to keep production and streaming traffic segregated. When PVS 6.1 was configured there was a host entry used for the Hostname to map to the PVS LAN IP address.


When I installing PVS 7.1 there is now an option to specify the management IP address. I assumed that this would be the production  LAN address and not the PVS LAN address.


I now see from another Konstantin post, the following ...


Otherwise, in a multi-homed environment we have seen the following action items resolve some replication status/inventory issues:


1) In ncpa.cpl (NIC Binding order) for PVS 6.1 servers - switch the PVS/Streaming NIC to the first place in the bindings. For 7.1 - put Management NIC first.

2) Modify the hosts record on the PVS servers to resolve FQDN of all PVS servers to their Streaming IP 6.1 and Management IP for 7.1.

Did you change your firewall rules by any chance? Typically Process Communication message means we are unable to contact the remote stores. Check out the following articles: CTX133333 and CTX138795 for port requirements. Also, make sure the PVS service account has read/write permissions to the stores. In this case a CDF trace and a WireShark would be useful for troubleshooting from data collection standpoint.

I thought that it could have been a remote issue but the datastore is local to the server.


I do have another theory, it turns out that the licenses server in the environment doesn't support PVS 7.1. After checking the eventvwr I see the error... Streamprocess - Unable to contact the license server and Licensing grace period expired. I've raised a change to upgrade the licensing server.

just fyi if you receive this after changing IP address of your PVS servers: Re-run PVS Config-Wizard.


In my case all works fine after changing IP addresses, however I wasn't able to create new vdisk versions receiving Error "Retry Limit Exhausted Error Code E0070004 " and "Process Communication" when validating Stores.
