VM Mount Operation Fails

Valid on Windows platforms.

Symptom:

A raw (full VM) mount operation or a file level VM mount operation failed.

Solutions:

To perform a raw (full VM) mount operation or a file level VM mount operation, VCB first takes a snapshot of a VM and then exports the files to the backup proxy system. There are several reasons this problem can occur and actions you can take to remedy this problem.

• Reason 1: There is not enough free disk space in the disk volume on the backup proxy system.

  Action 1: Clean up the disk or change the mount path to a different volume that has enough space.

• Reason 2: The VMware ESX Host system is down.

  Action 2: Take corrective action if the VMware ESX Host system on which the VM resides is down.

• Reason 3: VM has become temporarily unmountable.

  Action 3: Run vcbMounter utility for the VM on the backup proxy system, if the VM has become temporarily unmountable.

  You can run the utility using the command-line by navigating to the directory where VMware VCB framework is installed. To view the syntax for the utility, type the following in the command line:

  vcbMounter -help
  

  If the vcbMounter utility fails to mount the specified VM, then the problem could be with the VMware VCB framework. Restart the backup proxy system and resubmit the VM backup job.

• Reason 4: The backup source included VMs with an Independent (Persistent/Nonpersistent) disk mode specified.

  Action 4: Clear or Remove the Independent disk mode setting for all virtual disks associated with the VM.

• Reason 5: The job was submitted with incorrect VMware ESX Host or vCenter Server user credentials. The credentials were specified on the Security and Agent Information dialog.

  Action 5: Resubmit the VM backup job with valid credentials. You must provide valid VMware ESX Host system credentials or vCenter Server system credentials, and backup proxy system credentials on the Security and Agent Information dialog.

• Reason 6: A VM is no longer available in the VMware environment.

  Action 6: Run the ARCserve VMware Configuration Tool or ca_vcbpopulatedb utility to populate the CA ARCserve Backup database with updated information about your VMware environment.
