IDPA DP4400 - Process to Reset Initial Public facing IP addresses for ACM and ESXi Host

IDPA DP4400 - Process to reset Initial Public facing IP addresses for ACM and ESXi Host without performing a factory reset.

In the ACM Installation Wizard, the very first part of the install configures the public facing IP addresses for ACM (eth1) and ESXi Host (vmk0), together with default DNS, default route, etc.

If for any reason, the wrong addresses were originally entered and the rest of the IDPA installation has not been completed, then it is possible to reset the addresses to something other without following the procedure to clean up the system or do a factory reset.


NOTE: This process only applies if the IDPA 4400 has not been fully installed and the ACM Wizard is only at the initial network configuration stage for the ACM and ESX public facing IP addresses. If it is past that point, consult IDPA Support for additional assistance.

Brief:

• Recreate all DNS records, (all in lower case), to the required IP addresses.,
• As per best practice for IDPA deployment, ideally align the IP addresses in sequence for IDPA 4400, starting with the ACM as the first and lowest address.
• Reset the status on the ACM to: EULA_ACCEPTED
• Refresh the ACM URL and then redo the initial network configuration and completed full the installation.

Detailed Steps:

• Perform Steps 1 through 3 from a workstation already on the customer network.
• Perform steps 4 through to 12 from a workstation connected to the back of the IDPA Ethernet Service Port.
• Perform remaining steps from 14, on a workstation already on the customer network.

1. Delete ALL existing DNS records and confirm that the changes get replicated to ALL DNS servers.
2. Recreate the DNS records ideally in sequence as per example below:

3. Validate ALL DNS records using nslookip <IP-Address>.
4. Connect a windows workstation to the back of the IDPA 4400 Ethernet Service Port and assign an IP address of 192.168.100.98 with sub-net mask of 255.255.255.0.
5. SSH as to ACM internal IP address of 192.168.100.100 as user root and password as set by the customer. (Note that 192.168.100.100 is the factory default internal IP address of the ACM)
6. cd /usr/local/dataprotection/var/configmgr/server_data/status/
7. Take a backup copy of file applianceStatus.xml  - Issue command: cp -p applianceStatus.xml xx_applianceStatus.xml
8. Using vi, edit file applianceStatus.xml.
9. Change the <applianceState> line so that it reads: <applianceState>EULA_ACCEPTED</applianceState>
10. Save, exit and cat the file applianceStatus.xml file to confirm that the changes were correctly saved. The file should look as per below  example:

11. Open a web browser and connect to URL: https://192.168.100.100:8543
12. Enter the updated public facing IP addresses for the ACM and ESXi with correct subnet mask and complete the initial network configuration of the ACM wizard.
13. Disconnect the laptop from the backup of the IDPA Ethernet Service Port. 
14. From a workstation already on the customer network, connect to the ACM URL using the public facing IP address. From example, this would be: https://10.x.y.100:8543
15. Complete the remaining steps of the IDPA installation.
