Adaptec RAID Controller - Arcconf Setconfig; Arcconf Setcontrollermode

Examples
ARCCONF SETCACHE 1 LOGICALDRIVE 1 RON
ARCCONF SETCACHE 1 DEVICE 0 0 WB
arcconf setcong
Description
Resets the controller's conguration. Logical drives are deleted, hard disks are reset to the READY state,
and any controller settings are reset to default values.
Syntax
ARCCONF SETCONFIG <Controller#> DEFAULT [noprompt]
Parameters
Controller#
The controller number
Default
Restores the controller's default conguration.
Noprompt
No prompt for conrmation.
Examples
ARCCONF SETCONFIG 1 DEFAULT
arcconf setcontrollermode
Description
Sets the controller operating mode to one of the following:
• RAID Mode (default)—All RAID functions of the controller are enabled.
• Auto Volume Mode—All RAID functions of the controller are enabled. Attached drives without
Adaptec meta-data, but with an OS partition, are surfaced to the host operating system as RAW Pass
Through devices (similar to JBODs on legacy Adaptec controllers), where the RAID layer of the
controller rmware is bypassed when the host issues commands to the device . Attached drives
without Adaptec meta-data and without OS partitions, are automatically congured as Simple
Volumes (single drives with Adaptec meta-data), with these settings:
∘ Controller read caching is set to “Enabled” for rotating media.
∘ Controller write caching is set to “Enabled (write-back) when protected by battery/ZMM” for
rotating media.
∘ maxCache SSD read and write caching is enabled and the write caching policy is set to "write
back" for rotating media.
∘ Caching for non-rotating media is disabled.
By using DRAM caching, Auto Volume Mode can help reduce latency and accelerate performance,
especially if combined with a custom performance mode, such as Big Block Bypass (see arcconf
setperform on page 40 for more information).
• HBA Mode—The intent of this mode is to allow the RAID controller to act and be used as an HBA.
All attached drives are surfaced as RAW devices. Changing into HBA mode is allowed only if there
are no drives with Adaptec meta-data attached to the controller. Uninitialize the drives before
