Hi Guys,
I have two nodes clustered. Each node is AIX 5.2 & they are clustered with HACMP 5.2. The mode of the cluster is Active/Passive which mean one node is the Active node & have all resource groups on it & the 2nd node is standby.
Last Monday I noted that all resource groupes have been... (2 Replies)
Hi.
I have started heartbeat on two redhat servers. Using eth0.
Before I start heartbeat I can ping the two server to each other.
Once I start heartbeat both the server become active as they both have warnings that the other node is dead.
Also I am not able to ping each other. After stopping... (1 Reply)
Hi Guys,
I have to design a multinode hacmp cluster and am not sure if the design I am thinking of makes any sense.
I have to make an environment that currently resides on 5 nodes more resilient but I have the constrain of only having 4 frames. In addition the business doesnt want to pay for... (7 Replies)

Hi Experts,
I have configured HP-UX Service Guard cluster and it dumps crash every time i reboot a cluster node. Can anyone please help me to prevent these unnecessary crash dumps at the time of rebooting SG cluster node?
Thanks in advance.

scds_syslog_debug - write a debugging message to the system log
SYNOPSIS
cc [flags...] -I /usr/cluster/include file -L /usr/cluster/lib -l dsdev
#include <rgm/libdsdev.h>
void scds_syslog_debug(int debug_level, constchar *format...
DESCRIPTION
The scds_syslog_debug() function writes a debugging message to the system log. It uses the facility returned by the scha_cluster_getlogfa-
cility(3HA) function.
All syslog messages are prefixed with: SC[<resourceTypeName>,<resourceGroupName>,<resourceName>,<methodName>
If you specify a debug_level greater than the current debugging level being used, no information is written.
The DSDL defines the maximum debugging level, SCDS_MAX_DEBUG_LEVEL, as 9. The scds_initialize(3HA) function, which the calling program must
call before scds_syslog_debug(), retrieves the current debugging level from the file: /var/cluster/rgm/rt/<resourceTypeName>/loglevel.
Caution -
Messages written to the system log are not internationalized. Do not use gettext() or other message translation functions in conjunction
with this function.
PARAMETERS
The following parameters are supported:
debug_level Debugging level at which this message is to be written. Valid debugging levels are between 1 and SCDS_MAX_DEBUG_LEVEL,
which is defined as 9 by the DSDL. If the specified debugging level is greater than the debugging level set by the
calling program, the message is not written to the system log.
format Message format string, as specified by printf(3C)
... Variables, indicated by the format parameter, as specified by printf(3C)EXAMPLES
Example 1 Display All Debugging Messages
To see all debugging messages for resource type SUNW.iws, issue the following command on all nodes of your cluster
echo 9 > /var/cluster/rgm/rt/SUNW.iws/loglevel
Example 2 Suppress Debugging Messages
To suppress debugging messages for resource type SUNW.iws, issue the following command on all nodes of your cluster
echo 0 > /var/cluster/rgm/rt/SUNW.iws/loglevel
