About P460, P2404, and P4408 storage
controllers
The storage controllers support 12-Gbps data channels. Some storage controllers support caching,
which greatly improves performance and data security. For more information, access

This chapter is available for the following storage controllers:
RAID-P460-B2

Features
Operating modes
The storage controller supports the following operating modes:
HBA mode—In this mode, physical drives attached to the storage controller are exposed as
raw drives and RAID functions are disabled.
RAID mode—In this mode, RAID functions are enabled and RAID arrays can be created on
physical drives. Only logical drives are exposed to the operating system.
Mixed mode—This is the default mode. In this mode, RAID functions are enabled and RAID
arrays can be created on physical drives. Both logical drives and raw physical drives are
exposed to the operating system.
If the storage controller has RAID configuration, you must clear RAID configuration before
changing the operation mode of the storage controller to HBA mode. The new operating mode
takes effect after the server reboots.
For the new mode to take effect, restart the server after an operating mode change.
The operating system might fail to start up after the operating mode of the storage controller is
changed. To resolve this issue, reinstall the operating system. If the issue persists, contact
