Cloud computing and Virtualization

 I wanted to share my experience in fixing NFS issue during vCD 9.7 Linux based installation.  It is my first cell in the server group with CentOS 7 as operating system. The NFS server(centos) and client versions are v4. After configuring the first cell in the environment, the vCD service started successfully however when I tried to access vCD web port it was not accessible. 

 We need to follow set of prerequisite to migrate vRA(7.6) IAAS SQL database to a new AlwaysOn Availability Group (AAG) server. •    AlwaysOn Availability Group (AAG) is only supported with SQL Server 2016 Enterprise or SQL Server 2017 Enterprise •    Set DTC_Support = Per_DB in AAG  NOTE:  Starting with SQL Server 2016 (13.x) Service Pack 2 you can alter an availability group for distributed transactions. For SQL Server 2016 (13.x) versions before Service Pack 2, you need to drop, and recreate the availability group with the DTC_SUPPORT = PER_DB setting.
