PHD VBA will not Power On (VMware vSphere)

SUMMARY

PHD VBA will not Power On (VMware vSphere)

ISSUE

If you encounter an error when powering on a PHD Virtual Backup Appliance, for example, a lock error as seen in the image below, you may need to remove any attached snapshots that are no longer valid.

In some instances, when a PHD Virtual Backup Appliance is shutdown in the middle of a backup, it can leave behind a snapshot on the VM it was backing up. Also, that snapshot will remain attached to the powered off PHD Virtual Backup Appliance as an attached virtual disk. When the Appliance starts up, any leftover snapshots are removed by a snapshot cleanup process.

In environments using multiple PHD Virtual Backup Appliances, you may encounter a situation where a snapshot is left behind by a powered down PHD Virtual Backup Appliance but then that snapshot is removed by a second PHD Virtual Backup Appliance running the snapshot cleanup process. When you attempt to power on the original Appliance, you may encounter an error within vSphere Client, since the snapshot it had attached is no longer available. To start the Appliance, the snapshot must be removed. Follow the steps below to remove an attached snapshot from a PHD Virtual Backup Appliance.

To remove a leftover snapshot from a VBA

  1. Use vSphere Client and edit the PHD Virtual Backup Appliance's VM settings (right-click the PHD Virtual Backup Appliance VM and select Edit Settings).
  2. Select the attached snapshot disk.

    (Warning: do not remove an attached disk that is being used as backup storage or the VBA's operating system disk).

  3. Click Remove. The attached snapshot disk is deleted and the PHD Virtual Backup Appliance should power on successfully.
