If the disaster recovery topology contains any compute instances, use the following steps to prepare each compute instance for Full Stack DR:
- Create a block storage volume group in the same Availability Domain (AD) as the compute instance.
- Add the boot volume for the compute instance to the volume group created in Step 1.
- Add all block volumes attached to the compute instance to the volume group created in Step 1.
- If the DR workflow requires execution of user-defined (custom) scripts or commands on compute instances, set up IAM policies so you can run these commands using the Oracle Cloud Agent. Configure
sudo
access for a root
administrator on these instances if you want to invoke the scripts or commands with a different user ID.
