The order for H740P, H745, H745P MX, H840 is:
1. Non-RAID disks are enumerated first based on slot ID.
2. Virtual disks are enumerated second based on virtual disk target ID.
NOTE: If a virtual disk target ID occupies the slot ID, a non-RAID disk may not display in the slot order.
NOTE: OS enumeration may not be in this order if virtual disks or non-RAID disks are created while the operating system is
running. The operating system may name devices based on the order in which they were created resulting in the operating
system enumeration changing after reboot. It is recommended to reboot the system for the final device enumeration after
creating any virtual disks or non-RAID disks.
HII and PERC CLI can be used to identify non-RAID disk slot ID and device ID or virtual disk target ID. See the Virtual disk
management and Physical disk management sections for details on HII. For additional PERC CLI details, see the Dell EMC
PowerEdge RAID Controller Command Line Interface Reference Guide.
Controller mode
You can configure the controllers in two modes.
● RAID mode
● Enhanced HBA mode
RAID mode
RAID mode is the default mode for PERC 10 series controllers. In this mode, all RAID levels are accessible to the user for virtual
disk creation. Only online virtual disks are presented to the host, and all unconfigured or foreign disks are hidden from the host.
All controller models (H345, H740P, H745, H745P MX, and H840) support RAID mode.
NOTE:
In H345 controller, non-RAID disks can be created and assigned as boot devices in RAID mode. The H345 Controller
only supports RAID levels 0,1,10. See PERC Card Specifications for more details.
Enhanced HBA mode
Enhanced HBA mode or eHBA mode is an alternative mode for PERC 10 series controllers.
NOTE:
Older versions of OpenManage Storage Management and Comprehensive Embedded Management do not support
management of the controller in the eHBA mode.
NOTE: In the eHBA mode, non-RAID disks are enumerated first in ascending order, while RAID volumes are enumerated in
descending order. For more information, see the applicable systems management documentation.
NOTE: The only controllers that support eHBA mode are H740P, H745, and H745P MX. eHBA mode is not supported on
H345 and H840.
The major differences and similarities between RAID mode and eHBA mode are listed in the following table:
