VxRail üzerinde VCF: Yedekleme Yapılandırması Geçersiz Parametreyle Başarısız Oluyor

Kullanıcı, SFTP yedekleme yapılandırmasını uyguladıktan sonra aşağıdaki hatanın döndürüldüğünü görebilir:

Invalid parameter: Validation failed for directory path /path/to/backup/location" on server sftp.domain.com. Please make sure backup directory is intact and sftp server has write permissions on backup path.

Domainmanager.log aşağıdaki hatayı gösterir:

[centos-admin@CENTOS-9 ~]$ update-crypto-policies --show
DEFAULT

Bu sorunu çözmek için şunu ekleyin: ssh-rsa OpenSSH yapılandırma dosyasına:

1. Şunu ayarlayın: crypto-policies eski moda geçiş yapın.

   [centos-admin@CENTOS-9 ~]$ update-crypto-policies --set LEGACY

2. Sabit sürücünüz için bellenim güncelleştirmesi bulmak üzere openssh.config (emin olun ssh-rsa eklenir).
