|
|
### 1. Enhanced Monitoring (Pending)
|
|
- Alerting engine
|

|
- Enhanced health checks
|
|
|
|
### 2. MHVTL Integration (Future Enhancement)
|
|
- Actual MHVTL device discovery
|
|
- MHVTL config file generation
|
|
- Device node mapping
|
|
- udev rule generation
|
|
|
|
### 3. SCST Export Automation (Future Enhancement)

|
|
|
|
## 📝 Known Limitations
|
|
|
|
1. **Delete Library**: Requires library to be inactive first (by design for safety)
|
|
2. **MHVTL Integration**: Current implementation is database-only; actual MHVTL device integration pending
|
|
3. **Device Paths**: `device_path` and `stable_path` are NULL until MHVTL integration is complete
|
|
4. **Physical Tape**: Requires physical hardware for full testing
|
