The output is:

9. Run the following command to cold reboot the server:
serveraction powercycle
10. After the system completes POST and CSIOR, type the following command to verify the backplanerequestedmode:
get storage.enclosure.1.backplanerequestedmode
The output is:
BackplaneRequestedMode=None
11. Run the following to verify is the backplane mode is set to split mode:
get storage.enclosure.1.backplanecurrentmode
The output is:
BackplaneCurrentMode=SplitMode
12. Run the following command and verify that only 011 drives are displayed:
storage get pdisks

Viewing Universal Slots
Some of the 13th generation PowerEdge server backplanes supports both SAS/SATA and PCIe SSD drives in the same slot.
These slots are wired to the primary storage controller (PERC) and a PCIe extender card. These slots are called universal
slots. Backplane firmware provides information on the slots that support this feature. The backplane supports SAS/SATA disks
or PCIe SSDs. Typically the four higher number slots are universal. For, example, in a universal backplane supporting 24 slots,
slots 0-19 support only SAS/SATA disks while slots 20-23 support either SAS/SATA or PCIe SSD.
The roll-up health status for the enclosure provides the combined health status for all the drives in the enclosure. The enclosure
link on the Topology page display the entire enclosure information, irrespective of which controller it is associated with. As two
storage controllers (PERC and PCIe extender) can be connected to the same backplane, only the backplane associated with the
PERC controller is displayed in System Inventory page.
In the Storage > Enclosures > Properties page, the Physical Disks Overview section displays the following:
If a slot is empty, Slot Empty is displayed for the slot.
If there are no PCIe capable slots, then the PCIe Capable column is not displayed.
If it is a universal backplane with PCIe SSD in one of the slots, then the Bus Protocol column displays PCIe.
The Hotspare column is not applicable for PCIe SSD.
NOTE:
Hot swapping is supported for universal slots. If you want to remove a PCIe SSD drive and swap it with a SAS/
SATA drive, make sure to first complete the PrepareToRemove task for the PCIe SSD drive. If you do not perform this task,
the host operating system may have issues such as a blue screen, kernel panic, and so on.
Setting SGPIO Mode
The storage controller can connect to the backplane in I2C mode (default setting for Dell backplanes) or Serial General Purpose
Input/Output (SGPIO) mode. This connection is required for blinking LEDs on the drives. Dell PERC controllers and backplane
support both these modes. To support certain channel adapters, the backplane mode must be changed SGPIO mode.
The SGPIO mode is only supported for passive backplanes. It is not supported for expander-based backplanes or passive
backplanes in downstream mode. Backplane firmware provides information on capability, current state, and requested state.
