3 Run the following command to set the requested backplane mode to split mode:
racadm set storage.enclosure.1.backplanerequestedmode "splitmode"
The message is displayed indicating that the command is successful.
4 Run the following command to verify if the backplanerequestedmode attribute is set to split mode:
racadm get storage.enclosure.1.backplanerequestedmode
The output is:
BackplaneRequestedMode=None (Pending=SplitMode)
5 Run storage get controllers command and note down the controller instance ID.
6 Run the following command to create a job:
racadm jobqueue create <controller instance ID> -s TIME_NOW --realtime
A job ID is returned.
7 Run the following command to query the job status:
racadm jobqueue view -i JID_xxxxxxxx
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:

Viewing universal slots
Some 13
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 a PCIe extender card. The backplane rmware 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.
