Change Which SPP Is Managing DCU Activity (SPARC M7-16)
Change Which SPP Is Managing DCU Activity (SPARC
M7-16)
You cannot specify which SPM will serve as the DCU SPM or PDomain SPM, but you can
specify that Oracle ILOM should assign a new SPM in the pair to serve these roles. You might
do this when, for example, you are replacing an SPP.
Complete this task to change the current roles of the SPMs. For example, you would need to
change the SPM in the pair that is currently identified as the DCU SPM to be the Standby SPM
if you are replacing it.
On an SP, type:
-> set /System/DCUs/DCU_
x
initiate_sp_failover=true

SPARC M8 and SPARC M7 Servers Administration Guide
Prepare to Remove an SP
SPARC M8-8 and SPARC M7-8 servers have two SPs in the CMIOU chassis. SPARC M7-16
servers have two SPs in the switch chassis. On all servers, one SP serves as the Active SP, and
one serves as the Standby SP. The Active SP manages DCU activity and all system resources
unless it can no longer do so, in which case the Standby SP assumes its role.
Note -
Replace only one SP in the system at a time.
Note - If you issue the
prepare_to_remove
command for an SPM, you must also prepare
the SP for removal. You must then return the SP to service for the SPM to restart. This
automatically happens when an SP is physically removed and installed into the slot, but if you
do not physically install an SP into the slot, you must issue the
return_to_service
command
for the SP. See “Return a Component to Service” on page 75 .
This procedure explains how to prepare an SP for removal. For information about preparing
to remove the SPPs in a SPARC M7-16 server, see “Prepare to Remove an SPP (SPARC
M7-16)” on page 129 .
