When you merge a partition with its parent partition, the chosen partition and its replicas combine with the parent partition. You do not delete partitions---you only merge and create partitions to define how the directory tree is split into logical divisions, as shown in the following illustration.Figure 24
There are several reasons you might want to merge a partition with its parent:
Consider keeping partitions separate if the partitions are large (contain hundreds of objects), because large partitions slow down network response time.
The root-most partition in the tree cannot be merged because it is the top partition and has no parent partition to merge with.
The partition is merged when the process is completed on the servers. The operation could take some time to complete depending on partition sizes, network traffic, server configuration, etc.
IMPORTANT: Before merging a partition, check the partition synchronization of both partitions and fix any errors before proceeding. By fixing the errors, you can isolate problems in the directory and avoid propagating the errors or creating new ones.
Make sure all servers that have replicas (including subordinate references) of the partition you want to merge are up before attempting to merge a partition. If a server is down, eDirectory won't be able to read the server's replicas and won't be able to complete the operation.
If you receive errors in the process of merging a partition, resolve the errors as they appear. Don't try to fix the error by continuing to perform operations---doing so only results in more errors.
