Симптомы

The NetWorker VMware Protection (NVP) integration is configured with the vProxy appliance. When performing a backup, the vProxy is unable to open the VM's source VMDK with transport mode hotadd. This only impacts some VMs, but it is consistently the same VMs each time the workflow is run.

Причина

There is a snapshot of the failing VM still attached to the vProxy VM from a previous backup. At the end of a previous backup, the VM snapshot was not properly consolidated, so the snapshot remained mounted on the vProxy.

Разрешение

The ProxyHC utility can be used to cleanup any left behind disks or snapshots.

During VM backups, the vProxy sends a create snapshot request to the vCenter server, at the end of the backup a request is sent to remove the snapshot. The vProxy logs these requests in the /opt/emc/vproxy/runtime/logs/vbackupd/vbackupd-snapmgr.log. Responses to these requests come from the VMware API. If snapshots are not being removed in the VMware environment, it is recommended to engage VMware support:
