Limitations and Restrictions
-
Geographic Specificity
- Designed exclusively for South Korean Hangul standards – incompatible with North Korean (ko_KP) locale requirements
-
Hardware Constraints
- Unsupported on UCS B-Series blade servers due to firmware architecture differences
-
Mixed Environment Restrictions
- Primary/backup nodes must maintain identical locale packages (No hybrid ko_KR/en_US configurations allowed)
