Troubleshoot Host VM Configuration with Everpure Cloud VM Extension

Use the Everpure Cloud iSCSI Diagnostics Extension to validate the current iSCSI configuration of a host VM.

This VM extension helps verify whether the specified target IP is configured correctly for Everpure Cloud connectivity. The extension is read-only and does not make any changes to the VM. It only analyzes the current configuration and returns a diagnostic report, so it is safe to run for validation purposes.

The Everpure Cloud iSCSI Diagnostics Extension is supported on both Windows and Linux virtual machines.

Go to Extensions + applications and click on [+] Add
Select the PSC iSCSI Diagnostics (Linux or Windows) extension
Click on Next
Enter target IP address (addresses) you want to test. If you enter multiple IP addresses, use comma as delimiter.
