Resolution

NOTE: Before attempting the steps below, ensure that you have taken snapshots of each node in the cluster as per How to take a Snapshot of VMware Aria Operations.

Follow these steps on each node (Primary, Replica, Data):

1. Log in to all the nodes as the root user via SSH or console.
   
   

2. Back up the existing file:

   cd /storage/db/casa/webapp/hsqldb/
   cp casa.db.script casa.db.script.BAK

    

3. Stop the CASA service:

   service vmware-casa stop 

   Note: Make sure, casa service is stopped on all the nodes before you make the changes.

    

4. Edit the script file:

   • Open /storage/db/casa/webapp/hsqldb/casa.db.script in a text editor.

   • Search for "slice_name" inside INSERT INTO CASA_DOCS VALUES and look for the old node name in this line.

   • Replace it with the new node name.

   • Save and exit the file.
     
     

5. Start the CASA service again:

   service vmware-casa start

   
   Once the service is up the changes will be reflected on Ops.
