P.219 Configuring and viewing fans
Configuring the minimum fan speed
The minimum fan speed setting overrides the thermal configuration setting if the minimum fan speed is greater than the thermal configuration value

Configuring the thermal configuration setting
It might take several minutes before you can re-establish a connection
The thermal configuration setting overrides the minimum fan speed setting if the thermal configuration value is greater than the minimum fan speed value.

> 상대적으로 상위 냉각 설정이 우선한다는 ...

냉각 구성을 변경 후 적용하면, 자동으로 iLO가 리셋되는데, 한 번 더, iLO를 리셋하는것을 추천...

iLO 상에서, Cooling 설정 변경 후 저장하면,

iLO Web UI 및 BIOS 상에는 바로 적용되는데, ilorest로 조회되는 정보는 변경되지 않는다.

ThermalConfig=OptimalCooling

iLO reset을 2회(추가 한 번 더) 수행하면 적용된다.

ThermalConfig=IncreasedCooling

충분한(?) 시간을 기다려 본 것 같은데 변화하지 않은 것을 볼 때, 캐싱 정보가 업데이트 되지 않는 것으로 판단되고, 온라인에서, 서비스 영향 없이 수행하는 작업이니, iLO 리셋을 한 번 더 해서, 정확히 설정된 것을 확인하는 것이 좋다고 판단됨. (정신 건강이 ....)

RESTful API: ilorest 이용:

1. Open RESTful Interface Tool Console

2. execute below syntax command:
C:\> ilorest --nologo login iLO_IP_Address -u Administrative_Account -p Password --selector=Thermal.
C:\> ilorest rawpatch C:\temp\ilorest_cool.json

OneView의 Domain 확장(Scale up/Grow) 및 축소(Scale down/Shrink)

HPE Synergy Grow Best Practices Adding Enclosures to an Existing HPE OneView Logical Enclosure

도메인 확장의 경우, 구성이 잘못되지 않는 경우, 거의 서비스 다운 타임 없이 확장이 가능하다. 

그러나, 도메인 축소의 경우, 서비스 다운 타임이 반드시 필요하다.

기존 Oneview 도메인을 삭제 후, 축소된 도메인으로 새로 생성하는 작업으로 이해하면 된다.

Synergy를 운영 중, FLM 모듈을 재기동 해야할 상황이 있을 때,

Reset a Frame Link Module
https://support.hpe.com/hpesc/public/docDisplay?docId=emr_na-a00019536en_us#N101DF

Procedure

1. From the main menu, select SERVERS > Enclosures.
2. Select Actions > Reset link module.
3. Select the frame link module to reset.
   If there is only one frame link module, it is selected for you.
4. Click Yes, Reset.

Rebooting a frame link module

Note. Rebooting a frame link module will cause a brief disruption of the management ring network. The disruption may last up to 30 seconds.

Procedure

1. Connect to the HPE Synergy Console.
2. Select Actions > FLM Diagnostics > Reboot.
   The reboot pop-up window appears.
3. Choose either the Active or Standby frame link module.
4. Press Yes, reboot.

Performing a frame link module factory reset
https://techlibrary.hpe.com/docs/synergy/shared/ts/GUID-389527A1-3906-4196-A4A2-F07D320E8D5D.html
Note. The frame link module can be factory reset by pressing the front panel reset button until the front panel UID flashes or by using the HPE Synergy Console Actions menu. Hewlett Packard Enterprise recommends using the HPE Synergy Console to perform a factory reset.

Procedure

1. Connect to the HPE Synergy Console.
2. Select Actions > FLM Diagnostics > Factory Reset.
3. Click Yes, reset.
