clarify what you mean by "debug mode"
are you looking to increase logging into syslog.log?
for the cluster as whole?
and why?

Hello,

You did not specify which version of
Serviceguard is used.

The cmsetlog command (obsolete with SG A.11.19)
enables users to obtain a more verbose output
of cmcld. This is extremely useful if a
problem should be reproduced. cmsetlog allows
to set the log level and to restrict logging
to specific categories and modules.

From SG A.11.19 onwards you can start logging
for cmcld by adding the following lines in
the /etc/cmcluster.conf and do a
kill -SIGHUP .

CMCLD_LOG_FILE=/var/adm/cmcluster/cmcld.log
CMCLD_LOG_LEVEL=5

You can also enable debug logging for a
specific module only by setting in the same
file:

CMCLD_{module mnemonic}_LOG_LEVEL=5

where {module mnemonic} is one of the following:

ATN = Auto Trans
CDB = Configuration Database
CLM = Cluster Management
CMD = Commands
CML = SAF Distributed Lock Service
CMP = Config/Status Proxy
CMS = SAF Cluster Membership Service
CNF = Configuration
COM = Communication Server
CSV = Command Server
DFA = Disk File Access
DLK = Disk Lock
DLM = Distributed Lock Management
EVT = Cluster Management Event
GMD = Group Membership Server
GMS = Group Membership Service
LOC = Local Communication
LVM = Logical Volume Management
MDV = Module Version
MSG = Messaging
NET = Network Management
PKG = Package Management
PLE = Placement Engine
QSM = Quorum Service
REM = Remote Communication
RES = EMS Resources
SDB = Status Database
SEC = Security Service
SES = Sessions
SRV = Service Management
STA = Status Database API
SYN = Synchronization
UNK = Unknown
UTD = Utility Daemon

There is also debug logging of SG commands
using the '-D' option (SG A.11.18 and later)
If you want to change the logging for a
single command, you can specify -D {1-5} or
-O {filename) on the command line of any
commands. These command line options will
take precedence over the COMMAND_LOG_LEVEL/COMMAND_LOG_FILE values
specified in /etc/cmcluster.conf.

And so on.

As you can see, there are many ways to do it.

Cheers,
