HPE Smart Array SR Gen10 Controller - How to Change the Spare Management Mode
https://support.hpe.com/hpesc/public/docDisplay?docLocale=en_US&docId=emr_na-a00076345en_us
Changing the spare management mode
The spare management feature provides multiple methods for handling spare behavior. User can choose from the following options:

Dedicated - When the failed data drive is replaced, it must be rebuilt from the data on the spare drive. In Dedicated mode, one spare can be dedicated to multiple arrays.
Auto-Replace Drives - The spare for the failed data drive automatically becomes the replacement data drive. When the spare is replaced, the data drive does not need to be rebuilt. In Auto-replace mode, spare drives cannot be shared between arrays.

Auto-replace spare
Auto-replace spare allows an activated spare drive to become a permanent member of the drive array.
The original drive location becomes the location of the spare drive.
This method has the benefit of avoiding the copy-back operation after replacing the failed drive

Gen10 시스템의 Smart Array SR HBA fw가 1.98/1.99/2.62 인 경우, 신규 생성된 Logical Drive의 Surface Scan 중 inconsistent parity 오류가 발생할 수 있다.

Array 구성에 따라, 유효 데이터가 inconsistent stripe에 위치하는 경우, 수정 불가한 오류(URE) 및 Disk 장애를 유발할 수 있고, 고객 데이터의 문제(data integrity issues)를 일으킬 수 있어 조치가 필요하다.

SA HBA fw를 2.65로 업데이트 하여 사용하면 됨

VMware ESXi

Linux (x64)

Windows (x64)

증상 검토 관련 정보:
1. Windows 환경의 경우 Event ID 24677이 관찰될 수 있다.
(Linux는 오류를 기록하지 않아 발견하기 어렵다)
e.g.) Windows Event log
------------------------------------------------------
Message Id: 24677
Severity: Informational
Log message: Surface analysis has repaired an inconsistent stripe on logical drive connected to array controller .
------------------------------------------------------

2. SSA를 통해, 특정 LD의 Parity 상태 정보를 검토할 수 있다.
GUI> Controller Devices > Logical Devices > Logical Drive x from Array Y > Parity Initialization Status : Initialization Failed

CLI> 아래 명령 수행 후, Parity Initialization Status를 검토.
1) controller all show
2) controller slot=x logicaldrive all show
3) controller slot=x logicaldrive y show

증상을 경험 중인 fw 사용 중 불가피한 경우, Workaround로는 "offline Parity Initialization"을 이용한다. (Parity 초기화 완료 후 볼륨 사용)
