If you have selected a cluster pool as a DFS replica and it gets corrupted, the management context and the replica cannot be deleted.
When a DFS management context is created on an O or OU container object, two attributes are added to its container object in eDirectory:
DFS-VLDB-Hosts: Contains a list of the replica servers for the management context.
VLDB-Backend-ID: Contains the filename used for the VLDB, which is vdqad.
To resolve this issue, do the following:
Using iManager, delete the attributes: DFS-VLDB-Hosts and VLDB-Backend-ID from the O or OU container.
Using iManager, select Directory Administration > Modify Object.
Specify the container that is located in the DFS management context.
Click General > Other to display the Attributes.
From the Valued Attributes, select DFS-VLDB-Hosts, click Delete, then OK.
From the Valued Attributes, select VLDB-Backend-ID, click Delete, then OK.
If the VLDB process is running on the replicas, kill the process.
To get the process id of vldb, execute the following command:
ps -aef | grep vldb
Kill the process id received in Step 2.a.
The DFS management context is deleted.
