Problem Description:
When attempting to deploy a VMware proxy using the VMware Deployer tool, the following error is encountered:
Cause:
This error typically occurs when existing proxies are in a disconnected or maintenance state and have lingering virtual disks (VMDKs) attached. These disks interfere with the deployer tool’s ability to fetch the datacenter mapping correctly.
Resolution:
Follow the steps below to verify the state of existing proxies and remove unnecessary disks:
Step 1: Verify Proxy State
Log in to the Druva Management Console or the vCenter.
Check if any existing proxies are disconnected or in maintenance mode.
Step 2: Inspect Disks on Existing Proxies
Log in to vCenter or the ESXi host where the proxy is deployed.
Locate and select the affected Proxy VM.
Right-click and choose Edit Settings.
In the settings window, expand the Hard disk section and review the number of attached disks.
The proxy should typically have 4 disks.
Any disks beyond disk 4 may be residual from past backup or restore jobs.
Step 3: Manually Unmount Extra VMDK(s) from the Backup Proxy
To safely detach lingering VMDK(s) from the proxy:
Power off the backup proxy virtual machine.
Right-click the proxy VM and select Edit Settings.
Identify the unwanted Hard Disk(s) by checking the Disk File path.
Once verified, click the X mark next to the unwanted disk entry.
Important: Do NOT select the option “Delete files from datastore”.Click OK to save and close the configuration window.
Step 4: Retry Proxy Deployment
After confirming that unnecessary disks have been unmounted and the proxies are in a healthy state, attempt the proxy deployment again using the VMware Deployer tool.
