# WHATPORT(6389)

## NAME

port 6389 — clariion-evr01 — Registered to EMC for CLARiiON storage arrays; seen only around SAN management networks.

Protocol: TCP/UDP  
IANA registry

## DESCRIPTION

IANA lists 6389 TCP and UDP as clariion-evr01, registered by Dave DesRoches of EMC, and it belongs to the management side of the CLARiiON storage array line (later VNX, now Dell). There is no public protocol specification, so scanners label it from the registry rather than from a fingerprint. In practice you meet it on a storage management VLAN alongside the array's other administrative services, not on a general-purpose server.

## EXPOSURE

**Do not expose.** Storage-array control planes reach every LUN in the environment; keep them on an isolated management network with no route from the internet.

## CHECK

```sh
nc -vz TARGET 6389
```
