SPARC M7-16 servers have two SPPs in each CMIOU chassis and two SPs in the switch chassis. SPPs have two service processor modules each. SPs have one SPM each. This procedure explains how to remove an SPP.
For information about preparing SPs in the switch chassis for removal, see Prepare to Remove an SP.
To achieve redundancy, each SPM (SPM0 and SPM1) on an SPP is assigned to a different DCU. SPM0 on each SPP manages one DCU in the CMIOU chassis, while SPM1 on each SPP manages the other DCU in the chassis.

Before you remove an SPP, you must ensure that neither of the SPMs on the SPP are the DCU SPP (the SPP that manages DCU activity).
This example shows how to check the state of both SPMs on SPP2. See Oracle ILOM Paths for SPMs.
-> show /System/Other_Removable_Devices/Proxy_Service_Processors/ Proxy_Service_Processor_2/Service_Processor_Module_0 state_sp Properties: state_sp = OffDuty -> show /System/Other_Removable_Devices/Proxy_Service_Processors/ Proxy_Service_Processor_2/Service_Processor_Module_1 state_sp Properties: state_sp = OffDuty
If the state reports OffDuty, neither of the SPMs on SPP2 are managing a DCU. Move to Step 4.
If the state reports Running, you must change the DCU PDomain assignment. For example, if you want to remove SPP2 and it is currently running, you need to ensure that DCU2 is managed by /SYS/SPP3/SPM0 and that DCU3 is managed by /SYS/SPP3/SPM1. See Change Which SPP Is Managing DCU Activity (SPARC M7-16).
SPARC M8-8 and SPARC M7 servers running Oracle ILOM version 4.0.x do not require you to prepare the SPM for removal or verify that the SPMs and PCIe devices are offline.
-> set /System/Other_Removable_Devices/Proxy_Service_Processors/ Proxy_Service_Processor_2/Service_Processor_Module_0 action=prepare_to_remove -> set /System/Other_Removable_Devices/Proxy_Service_Processors/ Proxy_Service_Processor_2/Service_Processor_Module_1 action=prepare_to_remove
This command can take several minutes to complete.
It can take up to two minutes for the SPMs to go offline. Once they are offline, you can prepare the SPP for removal.
-> show /System/Other_Removable_Devices/Proxy_Service_Processors/ Proxy_Service_Processor_2/Service_Processor_Module_0 health Properties: health = Offline -> show /System/Other_Removable_Devices/Proxy_Service_Processors/ Proxy_Service_Processor_2/Service_Processor_Module_1 health Properties: health = Offline
-> show /System/Other_Removable_Devices/Proxy_Service_Processors/ Proxy_Service_Processor_2/Service_Processor_Module_0 state_pcie Properties: state_pcie = Offline
If state_pcie returns a value of Online, log onto the host and take the card offline for the appropriate SP/SPM slot. See Change Which SPP Is Managing DCU Activity (SPARC M7-16).
-> set /System/Other_Removable_Devices/Proxy_Service_Processors/ Proxy_Service_Processor_2 action=prepare_to_remove
This command powers off the SPP and turns on the blue Ready to Remove LED on the SPP.
-> show /System/Other_Removable_Devices/Proxy_Service_Processors/ Proxy_Service_Processor_2 health Properties: health = Offline
