Configuring high availability and disaster recovery for reservations

Setting up HA/DR using out-of-the-box tags and rules

Follow the steps given below to set up HA/DR using out-of-the-box tags and rules:

1. When you are Adding a Reservation, set the HA/DR required field to Yes.
   This creates a copy of all Reservation items for Disaster Recovery. The HA/DR tag is automatically attached to the copy of these Reservation items.
2. Navigate to the Placement Rules page and enable the HA/DR compatibility rule that is available out-of-the-box.
   Enabling this rule ensures that items with HA/DR tag are placed on Reservation Targets with the same tag.
3. Edit the Reservation Targets and associate the HA/DR tag to use the Reservation Targets for a HA/DR scenario.

Setting up HA/DR using custom tags and rules

Follow the steps given below to set up HA/DR using custom tags and rules:

1. Navigate to the Placement Rules page and disable the HA/DR compatibility rule that is available out-of-the-box.
2. Create a custom tag. For example, DisasterRecovery.
3. Attach the tag to all Reservations that you want to use for HA/DR scenarios.
4. Navigate to the Placement Rules page and create a new rule that uses the custom tag.
5. Edit the Reservation Targets and associate the custom tag to use the Reservation Targets for a HA/DR scenario.
