KBI 311316 Issue Addressed: DeviceMagic Rule Failed To Reach Device When DNS Name Is Used
Version
Argent Advanced Technology 3.1A-1510-A and earlier
Date
Tuesday, 1 December 2015
Summary
DeviceMagic with option ‘Test Host Device’ always reports ‘Failed to reach device xxx’ if the CMDB-X Node uses DNS name instead of IP address for Node name
However, if System Down Rule ‘NDE_PING’ runs OK with the same Node
The issue has been addressed in Argent AT 3.1A-1510-T9
Technical Background
The issue is caused by coding error
Argent for SNMP uses ICMP API to ping remote device
The API takes the IP address only
The DNS name must be resolved into IP address first
Directly passing in DNS name can result the failed ping or unpredictable status
Resolution
Upgrade to Argent AT 3.1A-1510-T9 or later
For customer who cannot upgrade immediately, he can specify the alternative IP for the device in CMDB-X
