Çözüm:

Biçimlendirilmemiş diski atlamak için bir kod düzeltmesi yayınlandı.

• NetWorker sunucusunu 19.7.0.x veya sonraki bir sürüme yükseltin.
• vProxies'i 4.3.0-29 veya sonraki bir sürüme yükseltin.
  • vProxy aygıtını yükseltme: https://www.dell.com/support/kbdoc/000197385/

Geçici Çözüm:

NetWorker 19.7.x ve vProxy 4.3.0-29'dan önce VM'yi Anında Kurtarma işlemini gerçekleştirin. Bu, Data Domain sistemindeki VM'nin geçici (çevrimdışı) bir kopyasını oluşturur. Gerekli diskler, kaynak (çevrimiçi) VM'ye bağlı NFS olabilir ve VM işletim sisteminden kopyalanır. Bu işlem aşağıdakiler altında ayrıntılı olarak anlatılmalıdır: https://www.dell.com/support/kbdoc/000158482
