Consolidating disks – unable to access file since it is locked

Had a vm which had flagged up as requiring disk consolidation
Attempting consolidation failed with the error ‘ Unable to access file since it is locked’

The error stack showed the following : msg.fileio.lock


Storage vMotion the disk to another data store and reattempt consolidation, this time it has cleared the locks and works. Nice and quick one, although not obvious.
Alternatively you could find the host that has a lock on the file and restart hostd, but depending on the environment this method can be a lot faster.

vSphere 6.7 Update 3 released!

vSphere 6.7 Update 3 has now been released. Among the new features:

Ability to change vCenter Server PNID/Hostname

PNID (Primary Network IDentifier of vCenter Server) is the host name of a vCenter and 6.7 Update 3 now supports changing this post-deployment. This will be great news to anyone who has had to rename or change the domain of a vCenter on prior releases and found it required a whole rebuild.

Support for multiple NVIDIA® vGPUs

VMware vSphere 6.7 Update 3 will introduce support for multiple NVIDIA GRID virtual GPUs (vGPU) per virtual machine to enable more graphics and compute intensive workloads running on vSphere. You will be able to configure up to four NVIDIA vGPUs connected to one virtual machine.

AMD EPYC™ Generation 2 support

The vSphere 6.7 U3 is compatible with the 2nd Generation of AMD EPYC™ processors.

Dynamic DNS support

With vSphere 6.7 Update 3, the usage of Dynamic DNS will be supported! vCenter will now support dynamically updating IP information in DNS, another manual job saved.

Driver Enhancements

Enhancements to VMXNET3: Guest encapsulation offload and UDP, and ESP RSS support to the Enhanced Networking Stack (ENS). Checksum calculations are offloaded from encapsulated packets to the virtual device emulation and you can run RSS on UDP and ESP packets on demand. The feature requires a corresponding VMXNET3 v4 driver.

Various driver updates will be shipped with 6.7 Update 3. The ixgben driver adds queue pairing to optimize CPU efficiency. The bnxtnet driver will support Broadcom 100 GbE network adapters and multi-RSS feeds. These are just some highlights, the following drivers are updated:

  • VMware nvme
  • Microchip smartpqi
  • Marvell qlnativefc
  • Broadcom lpfc/brcmfcoe
  • Broadcom lsi_msgpt2
  • Broadcom lsi_msgpt35
  • Broadcom lsi_msgpt3
  • Broadcom lsi_mr3
  • Intel i40en
  • Intel ixgben
  • Cisco nenic
  • Broadcom bnxtnet

Unable to update VCSA to 6.5 u2d

 If you are using any version of VCSA 6.5 U1d or below, you may come across this error whilst attempting to update to 6.5 U2d:

Latest updates already installed on vCSA, Nothing to stage/install

This is due to the way the VCSA updater processes build numbers on older versions. Fortunately, there is a workaround

Visit KB59659 at and download from the attechments on the article

  1. Log in as root via SSH to VCSA
  2. Run the command to enable the shell. shell
  3. Download the script attached to the article.
  4. Using a supported tool, sftp/scp the to the VCSA.
  5. Change the file name to and copy it to /root on the vCenter Server Appliance. cp /root/
  6. Run the command to execute permission: chmod +x /root/
  7. Run the command to execute the script: /root/
  8. Proceed with the update.

vCenter PSC converge tool now available for vCenter 6.5 with U2d

VMware is spreading some holiday cheer in the form of the latest update for vCenter 6.5 U2d. Buried in the release notes is:

  • vCenter Server 6.5 Update 2d adds a CLI tool to convert instances of vCenter Server Appliance with an external Platform Services Controller into vCenter Server Appliance with an embedded Platform Services Controller connected in Embedded Linked Mode. For more information, see the 6.7 vCenter Server Installation and Setup guide.
  • With vCenter Server 6.5 Update 2d, you can add VMware Platform Services Controller appliances to Active Directory 2016 domains.
  • With vCenter Server 6.5 Update 2d, you can use the new vRealize Operations Manager plug-in that provides specific metrics and high-level information about data centers, datastores, virtual machines, and ESXi hosts, to vCenter Server and vSAN. The plug-in is supported only in the vSphere Client.
  • With vCenter Server 6.5 Update 2d, the new vRealize Operations Manager plug-in adds by default the Patch method, supported by the HTTP protocol, to facilitate the online installation stage.
  • With vCenter Server 6.5 Update 2d, you can configure the property config.vpxd.macAllocScheme.method in the vCenter Server configuration file, vpxd.cfg, to allow sequential selection of MAC addresses from MAC address pools. The default option for random selection does not change. Modifying the MAC address allocation policy does not affect MAC addresses for existing virtual machines.

This feature was an eagerly awaited core feature of vCenter 6.7 U1 which has now been back-ported to 6.5.
While vCenter 6.5 Update 2 included support for enhanced linked mode using embedded PSCs, this was only good for new deployments leaving everyone with existing installations stuck with external PSCS. This feature allows us to migrate from a setup with external PSCs to embedded PSCs in a few easy steps.


  1. Edit the converge.json and decommission_psc.json templates to include information about the managing vCenter Server Appliance. See Preparing JSON Configuration Files for Reconfiguring External to Embedded Nodes for information on preparing the converge.json template.
    1. Confirm the appliances have been backed up
    1. Accept the thumb print
    1. Run the vcsa-util converge converge.json command on the client machine running on a Windows, Linux, or Mac OS operating system to begin the convergence process to install and configure the new embedded Platform Services Controller. See Syntax of the Converge Command for a list of available arguments for the vsca-util converge command.
    1. You can log into the vCenter Server Appliance appliance management interface (https://appliance-IP-address-or-FQDN:5480) and see that it is now a vCenter Server with embedded Platform Services Controller.
    1. Reconfigure any products that use the external PSC such as vRealize suite, NSX Manager, etc to use the new embedded Platform Services Controller.
    1. Run the vcsa-util decommission decomission.json command to decommission the original Platform Services Controller. This operation removes the external Platform Services Controller from the SSO domain.
    1. Shut down and delete the old PSC VMs.

Worth noting:

  • You still need to update all nodes, including existing external PSCs to 6.5 U2d before running this tool
  • This tool is only for vCenter Appliance (VCSA) deployments, not windows. If you have not already migrated from windows to vcsa, take this as a sign to do so sooner rather than later.
  • The external PSC configuration is being deprecated by VMware, so it is worth taking the time to migrate
