How to backup and restore the embedded vCenter Server 6.0 vPostgres database

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.

Troubleshooting “SSO log directory full” in vCenter Server Appliance 6.0

This video demonstrates how to troubleshoot “SSO log directory full” warnings in vCenter Server Appliance 6.0. This is a known issue affecting vCenter Server Appliance 6.0, and currently, there is no resolution. You see that the /storage/log directory is highly utilized in an Embedded vCenter Server Appliance or Platform Controller Server Appliance 6.0.

To work around this issue, reduce the maximum backup size and the maximum backup index in the log4j.properties file.

Note: In external Platform Service Controller (PSC) environments, log in to the Platform Service Controller instead to make the suggested changes.

Troubleshooting Virtual SAN Providers status- Disconnected

This video demonstrates how to troubleshoot Virtual SAN Providers which display the status as disconnected in the vSphere Web Client. This issue occurs if the SMS certificate for vCenter server is expired.

To resolve this issue, expired certificate will be removed and a new certificate will be generated.

Tips and tricks on Ruby vSphere Console (RVC) for managing a Virtual SAN environment

In this latest KBTV Webinar you will learn some great tips and tricks you can use in Ruby vSphere Console (RVC) for managing a Virtual SAN environment.

Covered in this video demonstration are various commands that can be used within Ruby vSphere Console (RVC), including:

  •  “vsan.disks_stats” Useful for capacity planning, management of disk groups and monitoring the health of physical disks
  •  “vsan.check_state” Useful for troubleshooting data unavailability situations and understanding object health in the VSAN cluster
  •  “vsan.resync_dashboard” Useful for visibility into data resync when changing storage policies
  •  “vsan.whatif_host_failures” Useful for capacity planning on future VSAN nodes and understanding VSAN’s ability to tolerate node failures

  • KB 2144018 / – In VMware NSX for vSphere 6.2.1, ESXi 5.5.x/6.0.x host experiences a purple diagnostic screen mentioning PFFilterPacket and VSIPDVFProcessSlowPathPackets
  • KB 2143397 / – In VMware NSX for vSphere 6.2.1, adding an ESXi host to the vSphere Distributed Switch fails with the error: Host <IP address> is not licensed for the VDS feature. Cannot add this host to dvSwitch
  • KB 2144314 In VMware NSX for vSphere 6.x, ESXi 5.5.x host experiences a purple diagnostic screen mentioning VdrProcessDhcpClientReq and VdrConsumeDhcp

Top troubleshooting issues:

  • KB 2144605Troubleshooting duplicate VXLAN VTEP vmk interfaces or IP addresses in VMware NSX for vSphere 6.x
  • KB 2137025IP address assignments to VXLAN Tunnel End Point (VTEP) and NSX host preparation fails with the error: Insufficient IP addresses in IP pool
  • KB 2144016In VMware NSX for vSphere 6.x, the NSX agencies on an ESXi host are uninstalled after unregistering the NSX Solution Plug-in
  • KB 2144200In VMware NSX for vSphere 6.x, installing or upgrading NSX VIBs fails with the error: ERROR: The pending transaction requires xxx MB free space, however the maximum supported size is xxx MB
  • KB 2126560 – Understanding and troubleshooting High Availability (HA) on the VMware NSX for vSphere 6.x Edge
    • ​Inline with other HA features, such as vSphere HA or MSCS, Edge HA is not designed to deliver zero downtime as the failover between appliances may require some services to be restarted.
    • ​NSX Edge HA is designed to minimize failover downtime. For example, it synchronizes the connection tracker of the statefull firewall, or the statefull information held by the load balancer. However, the time required to bring all services back up is not null. Examples of known service restart impacts include a non-zero downtime with dynamic routing when an Edge is operating as a router.
    • ​See also the 6.2.2 and 6.1.6 release notes – Fixed Issue [1573818]: [Traffic interrupted for 50 seconds after HA failover on ESG]

 

How to track the top field issues:

Web Client issues in vSphere 6

Today we’d like to talk about some common issues that have been seen when customers were upgrading to the latest version of our vSphere Web Client.

Perhaps you, during an upgrade, missed some products that were no longer supported (ie: removing plugins that are no longer supported), and now are proving to be reluctant to be removed. Most of these are not production stopping, though they are problematic when it is not expected.

KBs 2111224 and 211292 For customers who have upgraded and may have not seen the documentation on what other products are no longer supported in vSphere 6.0.

KB 1025360 Helps with removing plugins that are no longer compatible with vCenter 6.0.

KB 2119011 To help introduce customers to the feature changes in the vSphere Client and vSphere Web Client in 6.0 and any corresponding errors.

KB 2121185 After upgrading to vSphere 6.0 you may run into items no longer appearing in your inventory. This KB assists in troubleshooting to the services to find the cause.

KB 2121717 Troubleshoots login issues that customers may see in the vSphere environment using the Use Windows Session Credentials check box.

 

How to confirm ESX and ESXi host hardware compatibility

We’ve just put the finishing touches on a new video which discusses how to confirm ESX and ESXi host hardware compatibility using the VMware Hardware Compatibility Guides, which are available here.

You can use the VMware Hardware Compatibility Guides to confirm whether or not your particular server, system, HBA, network card, or other peripheral devices are certified and compatible for use with specific vSphere ESX and ESXi versions.

Additional information is available at Confirming ESX/ESXi host hardware (System, Storage, and I/O) compatibility (1003916).
