SmartArray/RAID mode vs. HBA mode

by 스쳐가는인연 2013. 7. 31.

ProLiant에는 (아직?) 지원하지 않는 HBA mode... 아마도 이 후로도 안 될 듯하지만 ...


Supports RAID or HBA mode for HP-UX only (no mixed mode). This can be configured through offline saupdate utility.


SAS Disk를 사용하는 경우 H/W Array가 필요하다면, RAID 모드를, 필요 없다면 HBA 모드를 사용하도록 되어 있다.

Determine whether the controller is in HBA mode or RAID mode; if necessary, change the mode to suit your configuration.

• Use RAID mode to take advantage of hardware-based fault-tolerant data storage methods such as RAID 1, RAID 1+0, or RAID 5. This reduces the amount of available storage space.

• Use HBA mode to access raw disks for increased storage capacity, to allow fault-tolerant storage to be managed by the enclosure firmware, or to implement software-based RAID modes using a volume manager.


NOTE: SATA disks are not supported when the Smart Array controller is in HBA mode


Determining and setting the controller mode

Use the saupdate.efi command with the get_mode and set_mode options to query or change the mode of the Smart Array P410i and Smart Array P411 controllers to HBA or RAID. Querying or changing modes is not supported for other controllers.


saupdate get_mode <controller>



saupdate set_mode <controller> <hba|raid> [-f]



NOTE: Commands are not case-sensitive. A system reset is not required after a mode change.

NOTE: After changing the mode, perform a reconnect -r command at UEFI.
