Cause

VM'ye bağlı bölümlenmemiş/biçimlendirilmiş bir disk var.

İşletim sistemi komutları, biçimlendirilmemiş diski doğrulamak için kullanılabilir:
  • fdisk -l
  • file -sL /dev/sd* dosyası
  • lsblk
  • blkid

Yukarıdaki komutlardan vm'ye bir aygıtın (/dev/sdb) bağlı olduğunu ancak biçimlendirme, bölüm veya veri olmadığını gösterebilirsiniz.

Resolution

Çözüm:

Biçimlendirilmemiş diski atlamak için bir kod düzeltmesi yayınlandı.

NetWorker belgeleri ve indirmeleri şu adreste mevcuttur: https://www.dell.com/support/home/product-support/product/networker/

SLR'yi yaparken, biçimlendirilmemiş bir diski atlayarak bildiriliyor:

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
