(Limited) vSphere management using a mobile device

On the VMware Labs website you can find a free appliance that can give you limited access to the management tools available in vSphere vCenter. The appliance is called vCMA or vCenter Mobile Access.

How to install?

  • Go to the vmware.com/labs website and download vCMA as a OVF. Jump to site
  • Extract the zip file that contains the OVF.
  • In vCenter, go File – Deploy from OVF and point to the extracted OVF file.
  • Once deployed, you can start the VM.
  • After the VM is started, there are 3 options to change settings
    • Using the menus on the console (to set network, timezone, login in to the command console)

    • Using the web interface https://vcma-host-or-ip:5480

       

    • Or using the command console. (use login in first screen)

       

      • By default the root account has as password vmware (remember the console is by default in qwerty)

 

Special configuration settings to thing about!

  • Set the IP to a fixed address
  • Enter the DNS servers
  • Change the default hostname and domainname. (http://communities.vmware.com/message/1335001)
  • Change the root default password using the passwd, in the command console

How to use?

  • It is very easy to start using this app.
  • Open a browser (on you PC or mobile device)
  • Point to http:// vcma-host-or-ip/vim (the folder /vim is needed and I hope VMware will change this in a next release)
  • Enter the vCenter server name and the userID and password you normally use in the vcenter.
  • Now you can do some functions like
    • vMotion
    • Edit settings of a VM
    • Change Powerstates of a VM
    • Etc, install and discover.

VSS issues when doing backups using VMware VDR

Hi,

During some consultancy projects @ SMB customers where we needed to install and configure VMware VDR to do some backups, we had some issues with Windows Machines and VSS. The result of the these errors with VSS was that the VDR backup jobs all failed.

Here some possible solutions (gonna try to keep the list up to date.)

  • VSS could not be started on a Windows 2003 server

We had to reregister all VSS DLL’s, restart the server and everything was working again. (check this)

VMware KB Articles about possible VDR / VSS issues.

A virtual machine can freeze under load when you take quiesced snapshots or use custom quiescing scripts KB 5962168

Because VDR is taking snapshots of your virtual machines this can also be a interesing KB
