Hitachi probe alarms displaying IP address instead of device name - DX UIM

Products

• DX Unified Infrastructure Management (Nimsoft / UIM)

Issue/Introduction

When generating alarms, Hitachi probe is creating alarms with the IP address in device name.  This behavior typically occurs when reverse DNS resolution is unavailable.

Environment

• DX UIM 23.4 and later
• hitachi 3.01 and later

Cause

The Hitachi probe attempts to resolve the connected device name via DNS.  If the expected device name cannot be resolved via DNS or the hosts file, the device name defaults to the IP address.

Resolution

Add device name entries to the hosts file on the server where the probe is running.  The hosts file will be accessed to provide device name information.

1. On a Windows server, edit the hosts file
   1. Open the Start menu, type Notepad, right-click it, and choose Run as administrator.
   2. Click File > Open and navigate to C:\Windows\System32\drivers\etc\.
   3. Change the file type dropdown from "Text Documents (.txt)" to "All Files (.*)" to see the hosts file, then open it.
   4. Add your new mapping at the bottom
      • (e.g., 127.0.0.1 mylocal.test).
   5. Click File > Save.
2. After the hosts file entries are added, restart the hitachi probe
   1. Deactivate the probe
   2. Activate the probe
3. Validate any new alarms that are generated have the device name populated with the information added to the hosts file instead of the IP address.
