IDPA 4400 : How to change ESXi root password and sync it with ACM

Steps to Change ESXi root password and sync it with ACM :
 
1. Log in to ACM using root user via putty and stop the webapp service. 
Command: service dataprotection_webapp stop
 
2. Log in to ESXi using root user via putty and change the password of ESXI root to common password.
 Command : passwd
 
Note: Give the common password which you have given during ACM initial configuration.
 
3. Log in to ACM using root user via putty
 
4. Create a copy of InfrastructureComponents.xml
 
Command: cd /usr/local/dataprotection/var/configmgr/server_data/config
 
Command: cp InfrastructureComponents.xml original_InfrastructureComponents.xml
 
5. Edit the infrastructure file, and modify *only* the 'password' tag as below:
 
Before modification, the file looks like this:
 

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<InfrastructureComponents>
    <ACM>
        <ipAddress>_customer_ip</ipAddress>
    </ACM>
    <ESXiHosts>
        <ESXi>
            <ipAddress>_customer_ip</ipAddress>
            <privateIpAddress>_customer_ip</privateIpAddress>
            <username>root</username>
            <password isEncrypted="true">nKWguK4OP0WU76mnsCY1+ScouI4Bgt9aJBtaYpLoHiO6XjXQuQ==</password>
            <isIdpaUserCreated>false</isIdpaUserCreated>
            <isRootPasswordChanged>false</isRootPasswordChanged>
        </ESXi>
    </ESXiHosts>
</InfrastructureComponents>


 Where the field highlighted in yellow can be different for different system, it is just a encrypted string.
 
 After modification, the file looks like this:
 

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<InfrastructureComponents>
    <ACM>
        <ipAddress>_customer_ip</ipAddress>
    </ACM>
    <ESXiHosts>
        <ESXi>
            <ipAddress>_customer_ip</ipAddress>
            <privateIpAddress>_customer_ip</privateIpAddress>
            <username>root</username>
            <password isEncrypted="false">**COMMON_PASSWORD**</password>
            <isIdpaUserCreated>false</isIdpaUserCreated>
            <isRootPasswordChanged>false</isRootPasswordChanged>
        </ESXi>
    </ESXiHosts>
</InfrastructureComponents>

Where **COMMON_PASSWORD** is your common password.

 
6. Start the ACM Service using the below command:
Command: service dataprotection_webapp start
 
7. Wait 10 minutes. Check the InfrastructureComponents.xml and make sure that the password tag value has changed for 'isEncrypted' = 'true'.
