+
+## [v1.7.0] - 2026-10-21
+### Fixed & Improved
+- **NetApp ONTAP REST API Active DC 감지 및 단독 스크립트 실행(Standalone) 지원 강화**:
+  - **REST API JSON 필드 매핑 수정 (`Modules/NetAppService.ps1`)**:
+    - ONTAP REST API `/api/protocols/cifs/domains`의 `discovered_servers` 하위 개체에서 도메인 컨트롤러 호스트명 키(`server_name`)가 `name`으로 잘못 매핑되어 실서버 연결 시에도 항상 가상 데모 DC(`dc04.corp.local`)로 폴백되던 버그 수정
+    - `server_name`, `server_ip`, `server_type`, `state`, `node.name` 필드 정상 파싱 및 `Active Connected` 상태 검증 로직 강화
+  - **파라미터 해석 헬퍼 (`Resolve-NetAppParameters`) 신설**:
+    - `NetAppService.ps1`을 GUI 애플리케이션 외부의 독립 PowerShell 콘솔에서 단독 발췌 실행할 때, `$Config` 객체 없이도 `-ClusterEndpoint`, `-Username`, `-Password`, `-SvmName`, `-UseLive` 파라미터만으로 즉각 실제 스토리지와 통신하도록 구조 개선
+    - `Get-NetAppActiveDc`, `Get-NetAppQtrees`, `Get-NetAppQuotas`, `Get-NetAppShares`, `New-NetAppQtreeAction`, `New-NetAppShareAction`, `Set-NetAppShareAcl`, `Set-NetAppQuotaRule` 등 모든 NetApp 모듈 함수에 단독 파라미터 전달 체계 적용
+  - **PowerShell 7 (Core) 자체 서명 SSL 인증서 우회(`-SkipCertificateCheck`) 호환성 확보**:
+    - Windows PowerShell 5.1의 `ServicePointManager` 방식 외에, PowerShell 7 `Invoke-RestMethod`의 `-SkipCertificateCheck` 매개변수를 동적 인식하여 SSL/TLS 핸드셰이크 예외 완벽 차단
+  - **다단계 API 엔드포인트 폴백 및 타임아웃 현실화**:
+    - 클러스터 도메인 질의 시 기본 타임아웃을 3초에서 15초로 현실화하여 노드 간 브로드캐스트 지연에 의한 타임아웃 예외 방지
+    - SVM별 필터 쿼리(`/api/protocols/cifs/domains?svm.name=...`), 전체 조회 쿼리(`?fields=discovered_servers,svm.name`), 컬렉션 단건 self-link 조회, 그리고 NetApp DataONTAP Toolkit(`Get-NcCifsDomainDiscoveredServer`)까지 4단계 복합 폴백 엔진 구축
+  - **상세 오류 추적 지원**:
+    - 실제 접속 실패 시 `Write-Warning`으로 각 엔드포인트별 에러 메시지를 즉시 출력하고, 반환 객체의 `FallbackReason` 속성에 기록하여 원인 분석을 용이하게 함

+### 5.3 PowerShell 콘솔에서 NetAppService.ps1 단독 발췌 테스트
+GUI 앱(ModernAdminStudio)을 띄우지 않고, 관리자 PowerShell 콘솔에서 모듈 파일만 단독으로 로드하여 NetApp Active DC 바인딩을 즉각 검증할 수 있습니다:
+
+```powershell
+# 1. 모듈 로드
+. .\Modules\NetAppService.ps1
+
+# 2. 클러스터 기본 연결 테스트
+Test-NetAppConnection -ClusterEndpoint "https://10.20.1.10" -Username "admin" -Password "YourPassword"
+
+# 3. NetApp이 현재 바인딩 중인 Active DC 실시간 조회
+$dcInfo = Get-NetAppActiveDc `
+    -ClusterEndpoint "https://10.20.1.10" `
+    -Username "admin" `
+    -Password "YourPassword" `
+    -SvmName "svm_cifs_prod01" `
+    -TimeoutSec 15
+
+# 4. 결과 확인 (ActiveDC, IP, 상태, 전체 발견된 DC 목록)
+$dcInfo | Format-List ActiveDC, ActiveDcIp, Node, SvmName, Status, State, DiscoveryMethod, IsLive
+$dcInfo.AllDiscoveredServers | Format-Table ServerName, ServerIp, ServerType, State, Node, SvmName
+```
+
+> **기술 참고 (REST API JSON Schema)**:  
+> ONTAP REST API `/api/protocols/cifs/domains`의 `discovered_servers[]` 배열에서 각 서버의 FQDN 호스트명 필드는 `name`이 아니라 **`server_name`**입니다. 스크립트 단독 호출 시 `-ClusterEndpoint`를 제공하면 자동으로 `UseLive = $true`로 승격되어 실제 REST API를 호출합니다.
