AWS Automated OS Configuration
Automated OS Configuration for AWS automatically installs the drivers required for fast and successful recovery operation on virtual machines running Windows or Linux operating systems. The virtual machines will automatically boot after failover or failback. Automated OS Configuration also enables recovery to any Availability Zone in the ZCA region.
Automated OS configuration requires no manual preparation of the VMs as it eliminates the need to run ZertoTools on the protected VM. In some cases running Zerto tools is still required. See ZertoTools for Windows.
The following operating systems are supported:
| • | Windows 2012R2, 2016 and 2019 |
| • | RHEL 7.4 and above |
| • | CentOS-7 based on RHEL 7.4 and above (Release 1708 and above) |
!
Important:
| • | When upgrading to 8.0, if a previous version of ZertoTools is installed, automated OS configuration will be used by default. |
| • | If ZertoTools for Windows version 3.0 is installed, automated OS configuration will not run allowing ZertoTools to be used instead. |
| • | If ZertoTools for Linux version 2.0 is installed, automated OS configuration will not run allowing ZertoTools to be used instead. |
| • | Volume partitions on protected Linux VMs need to be set according to the recommended partitions schema specified in: https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/installation_guide/sect-disk-partitioning-setup-x86#sect-recommended-partitioning-scheme-x86 |
| • | For Windows VMs only: Automated OS Configuration brings all volumes online on the recovered virtual machine regardless of the SAN policy settings. For example, if the SAN policy is set to online but one of the disks is set to offline, driver auto-installation will automatically bring that disk online. If you want to keep SAN policy setting offline, use ZertoTools for Windows, see ZertoTools for Windows. |
| • | Virtual machines running RHEL and CentOS versions 7.0-7.3 will not automatically boot unless the kernel is updated. Virtual machines running versions lower than 7.0 will not automatically boot. |
