Prevent Automatic SP or SPP Failover
Prevent Automatic SP or SPP Failover
The SPs and SPPs in the server are to failover automatically when the Oracle ILOM firmware
senses a fault or when a SP or SPP is taken offline. Before preparing to service an SP or SPP,
set the Oracle ILOM
/System/DCUs failover
property to
manual
. Setting the
failover
property to
manual
enables you to prepare an SP or SPP for service without interference from
the Oracle ILOM firmware.
Caution -
Only set the
failover
property to
manual
when servicing SPs and SPPs. After
servicing the SP or SPP, set the
failover
property back to
auto
so that the components will
failover properly in case of a fault or user command.
Note - This
failover
property was added to the Oracle ILOM firmware version 4.0. x . The
property will not be available on SPARC M7 servers running earlier versions of the Oracle
ILOM firmware. Always update your system firmware to latest available and supported version
for optimal performance, security, and stability.
On an SP, type:
-> set /System/DCUs failover=manual

Determine Which SP Is Managing System Activity
The SP that is identified as the Active SP manages system activity. On SPARC M8-8 and
SPARC M7-8 servers, this SP is located in the CMIOU chassis. On a SPARC M7-16 server, this
SP is located in the switch chassis.
The example shows that SP0 is assigned the status of the Active SP.
