Managing HP Serviceguard A.11.20.20 for Linux, May 2013

If you must disable identd, do the following on each node after installing Serviceguard but before
each node rejoins the cluster (For example, before issuing a cmrunnode or cmruncl).
For Red Hat and SUSE:
1. Change the value of the server_args parameter in the file /etc/xinetd.d/hacl-cfg
from -c to -c -i
2. Restart xinetd:
/etc/init.d/xinetd restart
5.3.6 Deleting the Cluster Configuration
You can delete a cluster configuration by means of the cmdeleteconf command. The command
prompts for a verification before deleting the files unless you use the -f option. You can delete
the configuration only when the cluster is down. The action removes the binary configuration file
from all the nodes in the cluster and resets all cluster-aware volume groups to be no longer
cluster-aware.
NOTE: The cmdeleteconf command removes only the cluster binary file $SGCONF/
cmclconfig. It does not remove any other files from the $SGCONF directory.
Although the cluster must be halted, all nodes in the cluster should be powered up and accessible
before you use the cmdeleteconf command. If a node is powered down, power it up and allow
it to boot. If a node is inaccessible, you will see a list of inaccessible nodes and the following
message:
Checking current status
cmdeleteconf: Unable to reach node lptest1.
WARNING: Once the unreachable node is up, cmdeleteconf
should be executed on the node to remove the configuration.
Delete cluster lpcluster anyway (y/[n])?
Reply Yes to remove the configuration. Later, if the inaccessible node becomes available, run
cmdeleteconf on that node to remove the configuration file.
5.4 Rebuilding the Deadman Driver
If you have upgraded the kernel to a new errata, the deadman driver must be rebuilt. The deadman
driver sources and associated files are located in the $SGROOT/drivers directory.
To rebuild the deadman driver:
1. Verify whether the deadman driver is already loaded:
# lsmod | grep deadman
2. Remove the deadman driver that is already loaded:
# rmmod deadman
3. To build and install the deadman driver module, run the following commands in the $SGROOT/
drivers directory:
a. # make modules
This command builds the module.
b. # make modules_install
This command installs the module.
c. # insmod deadman.ko
This command inserts the module.
