How to backup and restore the embedded vCenter Server 6.0 vPostgres database
Posted on October 18, 2016 by Ramesh B S
This video demonstrates how to backup and restore an embedded vCenter Server 6.0 vPostgres database. Backing up your database protects the data stored in your database. Of course, restoring a backup is an essential part of that function.
This follows up on our recent blog & video: How to backup and restore the embedded vCenter Server Appliance 6.0 vPostgres database.
Note: This video is only supported for backup and restore of the vPostgres database to the same vCenter Server. Use of image-based backup and restore is the only solution supported for performing a full, secondary appliance restore.

How to recreate a missing virtual machine disk descriptor file
http://kb.vmware.com/kb/1002511
This video demonstrates how to recreate a missing virtual machine disk descriptor .vmdk file.
Note: VMware recommends to attempt to restore the missing descriptor file from backups if possible. If this is not possible, proceed with recreating the virtual machine disk descriptor file.
To create a virtual machine disk descriptor file:
– Identify the size of the flat file in bytes.
– Create a new blank virtual disk that is the same size as the original. This serves as a baseline example that is modified in later steps.
– Rename the descriptor file (also referred to as a header file) of the newly-created disk to match the name of the original virtual disk.
– Modify the contents of the renamed descriptor file to reference the flat file.
– Remove the leftover temporary flat file of the newly-created disk, as it is not required.
This procedure will not work on virtual disks configured with a Para-virtualized SCSI controller in the virtual machine

Troubleshooting Virtual SAN on-disk format upgrade to 3.0 failures
Posted on October 13, 2016 by Ramesh B S
This video demonstrates how to troubleshoot Virtual SAN on-disk format upgrade to 3.0, which may fail in small Virtual SAN clusters or ROBO/stretched clusters.
https://kb.vmware.com/kb/2144944
This video demonstrates how to troubleshoot Virtual SAN on-disk format upgrade to 3.0, which may fail in small Virtual SAN clusters or ROBO/stretched clusters.
Attempting an on-disk upgrade in certain VSAN configurations may result in failure. Configurations that can cause these errors are:
– The stretched VSAN Cluster consists of two ESXi Hosts and the Witness Node also called ROBO configuration
– Each Host in the Stretched Cluster contains a single VSAN Disk Group
– A Virtual SAN cluster consists of three normal nodes, with one disk group per node
– A Virtual SAN cluster is very full, preventing the full data migration disk-group decommission mode
During this upgrade, a single point of failure is exposed. Follow all VMware best practices, and your business practices, regarding the backup of important data and virtual machines.
This exposure to additional failure risk is referred to as “reduced redundancy,” and must be manually specified in the Ruby vSphere Console or RVC to allow the upgrade to proceed.

VMware NSX as a Security Platform
Until now, there have really only been two enforcement points for security controls at our disposal: in the OS, and the Network. Each has their strengths and weaknesses. VMware NSX changes our options by opening up a new frontier for security, and the unique capabilities only a virtualized environment can offer.
