Introduction › Service Concepts › Propagation Types › Bound Propagation

Bound Propagation

Bound propagation indicates a bidirectional relationship between two CIs. If one CI is bound to another CI and either CI has a severity change, the change results in the same impact on both CIs.

Usage

Use bound propagation in the following situations:

• When a fault condition that affects one CI equally affects the other CI
• When two CIs are on the same hierarchical level and cannot function without each other

Examples

Examples of appropriate situations to use bound propagation include the following:

• Mirrored disks may require bound propagation with one another.
• A Database CI connected to an Application CI may have bound propagation with a replication database CI that belongs to a related replication server.

USM Relationships

The following USM relationships map to bound propagation by default in CA SOI:

• Is Bound To
• Is Clone Of
• Is Connected To
• Is Result Of

You must select one of these relationships when you assign bound propagation. For example, you could assign Is Bound To to a set of mirrored disks. When bound propagation is automatically assigned to a relationship, the default relationship assignment is Is Bound To.
