DETERMINING AND SETTING THE CONTROLLER MODE The Smart Array P411/256 controller has two operating modes: o 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. RAID mode is supported on HP-UX and Windows; it is the required operating mode for servers running Windows. o 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. [Important] Important: SATA disks are not supported when the Smart Array controller is in HBA 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. GET_MODE This option displays the current mode of the controllers. Syntax saupdate get_mode can be any one of the strings listed in Table 1. Table 1 strings +------------------------------------------------------------------------+ | | Meaning | |--------------------+---------------------------------------------------| | | A controller having the PCI segment id, bus id, | | | device id and function id is addressed | |--------------------+---------------------------------------------------| | all | Addresses all controllers in the system | |--------------------+---------------------------------------------------| | | Controllers of a particular type indicated by the | | | string are addressed | +------------------------------------------------------------------------+ SET_MODE [Important] Important: If you are using HBA mode, do not install any disk that has previously been a part of a RAID volume into the system. Use set_mode to change the mode of the controller. If the controller is already in the required mode the following message appears: The controller at is already in HBA|RAID mode Syntax saupdate set_mode [-f] can be any one of the strings listed in Table 3-1. An alert message about the possible data loss is displayed when a mode change command is issued. A confirmation is required before the actual mode change is made. This ensures that an unintentional change of mode does not happen. The -f indicates the user is aware of the changes that are being made, and no warning message or confirmation regarding the mode change is needed. set mode [Note] Note: Commands are not case-sensitive. A system reset is not required after a mode change. [Note] Note: After changing the mode, perform a reconnect -r command at UEFI.
