Prepare To Remove An Spp (Sparc M7-16) - Oracle SPARC M8 Service Manual

Prepare to Remove an SPP (SPARC M7-16)

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
an SP" on page
If you issue the prepare_to_remove command for an SPM, you must also prepare
Note -
the SPP for removal. You must then return the SPP to service for the SPM to restart. This
automatically happens when an SPP is physically removed and installed into the slot, but if you
do not physically install an SPP into the slot, you must issue the return_to_service command
for the SPP. See
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).
