and create the symbolic link
by running t

Troubleshooting
Processes
P
rocess
es
such as
mxdomainmgr
can
take time (up to 2 minutes on minimum platform requirements
based machine
)
to start
.
Consequently
:

Do not attempt to log in to HP SIM immediat
ely
after Serviceguard Manager
displays
the package
.

T
ake
the
2 minutes into account when testing failover scenarios.

If required, adjust the
sleep timer (within the sgsim script)
to
fit the failover process.
SNMP communications
SNMP uses the User Datagr
am Protocol (UDP) as the transport protocol for passing data between
managers and agents
. In a clustered configuration
,
HP SIM
uses
the real IP address instead of the
virtual
address
to answer
UDP requests.
To resolve this issue, you must use
address trans
lation on the
UDP
and use
the embedded kernel firewall stack of Linux to achieve it. You must SNAT the
udp
packets, by using the
iptables
command
.
A
dd the following line to the
/etc/rc.local
file on
each node:
#
iptables
-
t nat
-
A POSTROUTING
-
p udp
-
j SNA
