The action that must first be performed to ensure that there are no issues with Horizon LDAP

replication within the Pod is to execute repadmin.exe/showrepl localhost:389. This command will

display the replication status of the local Connection Server instance and show any errors or warnings

that might affect the replication process1. The administrator should run this command on each

Connection Server instance in the Pod before upgrading them in parallel, and resolve any issues that

are reported.

The other options are not valid or feasible because:

Executing ViewDBChk.cmd --scanMachines will not check the Horizon LDAP replication status, but

rather scan the vCenter Server inventory for virtual machines that are managed by Horizon and

report any inconsistencies or errors2. This command is useful for troubleshooting virtual machine

issues, but not for verifying LDAP replication.

Executing vdmexport.exe -f Myexport.lDF will not check the Horizon LDAP replication status, but

rather export the Horizon LDAP configuration data to a file named Myexport.lDF3. This command is

useful for backing up or restoring the Horizon LDAP data, but not for verifying LDAP replication.

Executing vdmadmin.exe -S will not check the Horizon LDAP replication status, but rather display the

health status of the Connection Server instances in the Pod4. This command is useful for monitoring

the Connection Server performance and availability, but not for verifying LDAP replication.
