 Лечение такое:  
1. Заходим в консоль ESXi и смотрим список подключений
[root@esxi:~] esxcfg-nas -l
в моем случае пусто
2. Отключаем VeeamBackup_TS-FS01, где TS-FS01 имя сервера
[root@esxi:~] esxcfg-nas -d VeeamBackup_TS-FS01
IORM: failed to disable IORM: Unable to get console path for volume, VeeamBackup_TS-FS01
NAS volume VeeamBackup_TS-FS01 deleted.
3. Все работает. Повторное монтирование образа виртуальной машины проходит успешно
