where, JID_xxxxxxxx is the job ID from step 6.
The status is displayed as Pending.
Continue to query the job ID until you view the Completed status (this process may take up to three minutes).
8. Run the following command to view the backplanerequestedmode attribute value:
racadm get storage.enclosure.1.backplanerequestedmode
The output is:
BackplaneRequestedMode=SplitMode
9. Run the following command to cold reboot the server:
racadm serveraction powercycle
10. After the system completes POST and CSIOR, type the following command to verify the backplanerequestedmode:
racadm 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:
racadm get storage.enclosure.1.backplanecurrentmode
The output is:
BackplaneCurrentMode=SplitMode
12. Run the following command and verify that only 011 drives are displayed:
racadm storage get pdisks

Viewing universal slots
Some 14
th
generation PowerEdge server backplanes supports both SAS/SATA and PCIe SSD drives in the same slot. These
slots are called universal slots and are wired to the primary storage controller (PERC) and either PCIe extender card or direct
connect manager by CPU backplanes supports both SAS/SATA and PCIe SSD drives in the same slot. The backplane firmware
provides information about 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 that supports 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 displays the entire enclosure information irrespective of which controller it is associated with.
Because 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:
Slot Empty If a slot is empty.
PCIe Capable If there are no PCIe capable slots, this column is not displayed.
Bus Protocol If it is a universal backplane with PCIe SSD installed in one of the slots, this column displays PCIe.
Hotspare This 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, ensure that you 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.
