From 939a8f7322238592ddda66f3faa3a43af4e60de6 Mon Sep 17 00:00:00 2001 From: Christian Berendt Date: Fri, 21 Nov 2025 23:12:27 +0100 Subject: [PATCH] Consolidate NetBox device lookup into centralized utility - Create osism/utils/netbox.py with find_device_by_identifier() - Refactor 9 files to use centralized function: - osism/api.py - osism/commands/baremetal.py (5 locations) - osism/commands/sonic.py - osism/commands/console.py - osism/commands/netbox.py - osism/tasks/conductor/utils.py - osism/tasks/conductor/sonic/sync.py - osism/utils/ssh.py - Add comprehensive logging and error handling - Maintain backward compatibility This reduces code duplication by ~40 lines and improves maintainability by providing a single source of truth for device lookup operations.
