Port availability for deployed operating systems

Some ports are blocked by certain operating-system profiles. The following tables list the ports that are open (not blocked).

Ensure that the hypervisor that is running the Lenovo XClarity Administrator appliance allows network traffic (TCP/UDP) on ports 139, 445, 3001, 3900, 8443. These are required for operating-system deployment.

RHEL Virtualization profile

By default, the Red Hat Enterprise Linux (RHEL) Virtualization profile blocks all ports except for those that are listed in the following table.

SLES Virtualization, Basic, and Minimal profiles

For SUSE Linux Enterprise Server (SLES), some open ports are dynamically assigned based on the operating system version and profiles. For a complete list of open ports, see your SUSE Linux Enterprise Server documentation.

VMware ESXi Virtualization profile

For a complete list of open ports for VMware vSphere Hypervisor (ESXi) with Lenovo customization, see the VMware documentation for ESXi on the VMware Knowledge Base website.

Windows profiles

The following ports must be available for Windows profiles.
