Designing Disaster Recovery Clusters using Metroclusters and Continentalclusters, Reprinted October 2011 (5900-1881)

IMPORTANT: Starting with Continentalclusters A.08.00, multiple log files are used to log various
operations. All log messages are stored in the /var/adm/cmconcl/logs directory with
appropriate names.
• The monitoring daemon, by default, logs messages into the /var/adm/cmconcl/logs/
cmclsentryd.log file.
• Continentalclusters commands, such as cmquerycl, cmcheckconcl, cmapplyconcl, and
cmrecovercl, log messages into the standard output as prior versions. In addition, these
commands log messages into the following files:
◦ The cmapplyconcl command logs messages to the /var/adm/cmconcl/logs/
cmapplyconcl.log file.
◦ The cmcheckconcl command logs messages to the /var/adm/cmconcl/logs/
cmcheckconcl.log file
◦ The cmswitchconcl command logs messages to the /var/adm/cmconcl/logs/
cmswitchconcl.log file.
◦ The cmforceconcl command logs messages to the /var/adm/cmconcl/logs/
cmforceconcl.log file.
◦ The cmrecovercl command logs messages to the /var/adm/cmconcl/logs/
cmrecovercl.log file.
◦ The split brain prevention module (vpaccrlb) logs messages to the /var/adm/
cmconcl/logs/checkpkg.log file
◦ The cmviewconcl command logs messages in the /var/adm/cmconcl/logs/
cmviewconcl.log file.
• The Continentalclusters EMS resource monitor continues to log messages to the /etc/opt/
resmon/log/api.log and the registrar logs messages to the /etc/opt/resmon/log/
registrar.log.
The Continentalclusters EMS client, by default, logs messages to the /etc/opt/resmon/
log/client.log file.
Deleting Continentalclusters Configuration
The cmdeleteconcl command is used to delete the configuration on all nodes in the
Continentalclusters configuration. To delete Continentalclusters and the Continentalclusters
configuration.
# cmdeleteconcl
NOTE: If modifying the configuration, re-issue the cmapplyconcl command. There is no need
to delete the previous configuration.
While deleting a Continentalcluster configured with the recovery group maintenance feature, the
shared disk is not removed. Before applying a fresh Continentalclusters configuration using an old
shared disk, you must re-initialize the file system in the shared disk using the mkfs command.
Renaming a Continentalclusters
To rename an existing Continentalclusters, perform the following steps:
1. Remove the Continentalclusters configuration.
# cmdeleteconcl
2. Edit the CONTINENTAL_CLUSTER_NAME field in the configuration ASCII file, and run the
cmapplyconcl command to configure the Continentalclusters with a new name.
