prevents unpredictable behavior from corrupting the data on the shared
disks. See the
clexit.rc
man page for additional information.
8.2.4 Starting and Stopping Cluster Services on Clients
Use the
/usr/sbin/cluster/etc/rc.cluster
script or the
startsrc
command to
start
clinfo
on a client, as shown below:
/usr/sbin/cluster/etc/rc.cluster
You can also use the standard AIX
startsrc
command:
startsrc -s clinfo
Use the standard AIX
stopsrc
command to stop
clinfo
on a client machine:
stopsrc -s clinfo
8.2.4.1 Maintaining Cluster Information Services on Clients
In order for the clinfo daemon to get the information it needs, you must edit
the /usr/sbin/cluster/etc/clhosts file. As installed, the clhosts file on an
HACMP client node contains no hostnames or addresses. HACMP server
addresses must be provided by the user at installation time. This file should
contain all boot and service names or addresses of HACMP servers from any
cluster accessible through logical connections with this client node. Upon
startup,
clinfo
uses these names or addresses to attempt communication
with a
clsmuxpd
process executing on an HACMP server.
An example list of hostnames/addresses in a clhosts file follows:
n0_cl83 # n0 service
n2_cl83 # n2 service
n3_cl83 # n3 service
For more detailed information on the clinfo command refer to Chapter 2,
“Starting and Stopping Cluster Services”,
HACMP for AIX, Version 4.3:
Administration Guide , SC23-4279.
Never use the
kill -9
command on the
clstrmgr
daemon. Using the
kill
command causes the
clstrmgr
daemon to exit abnormally. This causes the
SRC to run the /usr/sbin/cluster/utilities/clexit.rc script which halts the
system immediately, causing the surviving nodes to initiate failover.
