Table 1-2 provides a starting point for administering your cluster.
Note - The Oracle Solaris Cluster commands that you run only from the global-cluster voting node are not valid for use with zone clusters. See the appropriate Oracle Solaris Cluster man page for information about the valid use of a command in zones.
Table 1-2 Oracle Solaris Cluster Administration Tools
|
The Cluster Control Panel (CCP) provides a launchpad for the cconsole, crlogin, cssh, and ctelnet tools. All tools start a multiple-window connection to a set of specified nodes. The multiple-window connection consists of a host window for each of the specified nodes and a common window. Input to the common window is sent to each of the host windows, enabling you to run commands simultaneously on all nodes of the cluster.
You can also start cconsole, crlogin, cssh, or ctelnet sessions from the command line.
By default, the cconsole utility uses a telnet connection to the node consoles. To establish secure shell connections to the consoles instead, enable the Use SSH checkbox in the Options menu of the cconsole window. Or, specify the -s option when you issue the ccp or cconsole command.
See the ccp(1M) and cconsole(1M) man pages for more information.
The phys-schost# prompt reflects a global-cluster prompt. Perform this procedure on a global cluster.
This procedure provides the long forms of the Oracle Solaris Cluster commands. Most commands also have short forms. Except for the long and short forms of the command names, the commands are identical.
Before You Begin
Verify that the following prerequisites are met before starting the CCP:
Install the SUNWccon package on the administrative console.
Ensure that the PATH variable on the administrative console includes the Oracle Solaris Cluster tools directories, /opt/SUNWcluster/bin and /usr/cluster/bin. You can specify an alternate location for the tools directory by setting the $CLUSTER_HOME environment variable.
Configure the clusters file, the serialports file, and the nsswitch.conf file if you are using a terminal concentrator. The files can be either /etc files or NIS or NIS+ databases. See the clusters(4) and serialports(4) man pages for more information.
phys-schost# ccp clustername
The CCP launchpad is displayed.
Perform this procedure to establish secure shell connections to the consoles of the cluster nodes.
Before You Begin
Configure the clusters file, the serialports file, and the nsswitch.conf file if you are using a terminal concentrator. The files can be either /etc files or NIS or NIS+ databases.
Note - In the serialports file, assign the port number to use for secure connection to each console-access device. The default port number for secure shell connection is 22.
See the clusters(4) and serialports(4) man pages for more information.
# cconsole -s [-l username] [-p ssh-port]
Enables secure shell connection.
Specifies the user name for the remote connections. If the -l option is not specified, the user name that launched the cconsole utility is used.
Specifies the secure shell port number to use. If the -p option is not specified, the default port number 22 is used for the secure connections.
The clsetup utility enables you to interactively configure quorum, resource group, cluster transport, private hostname, device group, and new node options for the global cluster. The clzonecluster utility performs similar configuration tasks for a zone cluster. For more information, see the clsetup(1CL) and clzonecluster(1CL) man pages.
The phys-schost# prompt reflects a global-cluster prompt. Perform this procedure on a global cluster.
This procedure provides the long forms of the Oracle Solaris Cluster commands. Most commands also have short forms. Except for the long and short forms of the command names, the commands are identical.
phys-schost# clsetup
phys-schost# clsetup
The Main Menu is displayed.
phys-schost# clzonecluster configure sczone
You can view the available actions in the utility with the following option:
clzc:sczone> ?

% cluster show
Running the cluster show command from a global-cluster voting node shows detailed configuration information about the cluster and information for zone clusters, if you have configured them.
You can also use the clzonecluster show command to view the configuration information for just the zone cluster. Properties for a zone cluster include zone-cluster name, IP type, autoboot, and zone path. The show subcommand runs inside a zone cluster, and applies only to that particular zone cluster. Running the clzonecluster show command from a zone-cluster node retrieves status only about the objects visible to that specific zone cluster.
To display more information about the cluster command, use the verbose options. See the cluster(1CL) man page for details. See the clzonecluster(1CL) man page for more information about clzonecluster.
Example 1-6 Viewing the Global Cluster Configuration
The following example lists configuration information about the global cluster. If you have a zone cluster configured, it also lists that information.

You can also view the NAS devices that are configured for global or zone clusters, by using the clnasdevice show subcommand or the Oracle Solaris Cluster Manager. See the clnasdevice(1CL) man page for more information.
The cluster(1CL) command uses the check subcommand to validate the basic configuration that is required for a global cluster to function properly. If no checks fail, cluster check returns to the shell prompt. If a check fails, cluster check produces reports in either the specified or the default output directory. If you run cluster check against more than one node, cluster check produces a report for each node and a report for multinode checks. You can also use the cluster list-checks command to display a list of all available cluster checks.
Beginning in the Oracle Solaris Cluster 3.3 5/11 release, the cluster check command is enhanced with new types of checks. In addition to basic checks, which run without user interaction, the command can also run interactive checks and functional checks. Basic checks are run when the -k keyword option is not specified.
Interactive checks require information from the user that the checks cannot determine. The check prompts the user for the needed information, for example, the firmware version number. Use the -k interactive keyword to specify one or more interactive checks.
Functional checks exercise a specific function or behavior of the cluster. The check prompts for user input, such as which node to fail over to, as well as confirmation to begin or continue the check. Use the -k functional check-id keyword to specify a functional check. Perform only one functional check at a time.
Note - Because some functional checks involve interrupting cluster service, do not start any functional check until you have read the detailed description of the check and determined whether you need to first take the cluster out of production. To display this information, use the following command:
% cluster list-checks -v -C checkID
You can run the cluster check command in verbose mode with the -v flag to display progress information.
Note - Run cluster check after performing an administration procedure that might result in changes to devices, volume management components, or the Oracle Solaris Cluster configuration.
Running the clzonecluster(1CL) command at the global—cluster voting node runs a set of checks to validate the configuration that is required for a zone cluster to function properly. If all checks pass, clzonecluster verify returns to the shell prompt and you can safely install the zone cluster. If a check fails, clzonecluster verify reports on the global-cluster nodes where the verification failed. If you run clzonecluster verify against more than one node, a report is produced for each node and a report for multinode checks. The verify subcommand is not allowed inside a zone cluster.

# cluster check -v -o outputdir
Verbose mode
Redirects output to the outputdir subdirectory.
The command runs all available basic checks. No cluster functionality is affected.
# cluster check -v -k interactive -o outputdir
Specifies running interactive validation checks
The command runs all available interactive checks and prompts you for needed information about the cluster. No cluster functionality is affected.
# cluster list-checks -k functional
For example, a functional check might trigger a node panic or a failover to another node.
# cluster list-checks -v -C checkID
Specifies a specific check.
# cluster check -v -k functional -C checkid -o outputdir
Specifies running functional validation checks
Respond to prompts from the check to confirm that the check should run, and for any information or actions you must perform.
Note - For record-keeping purposes, specify a unique outputdir subdirectory name for each check you run. If you reuse an outputdir name, output for the new check overwrites the existing contents of the reused outputdir subdirectory.

>>> Functional Check <<<
'Functional' checks exercise cluster behavior. It is recommended that you
do not run this check on a cluster in production mode.' It is recommended
that you have access to the system console for each cluster node and
observe any output on the consoles while the check is executed.
If the node running this check is brought down during execution the check
must be rerun from this same node after it is rebooted into the cluster in
order for the check to be completed.

The /var/cluster/logs/commandlog ASCII text file contains records of selected Oracle Solaris Cluster commands that are executed in a cluster. The logging of commands starts automatically when you set up the cluster and ends when you shut down the cluster. Commands are logged on all nodes that are up and booted in cluster mode.
Commands that are not logged in this file include those commands that display the configuration and current state of the cluster.
Commands that are logged in this file include those commands that configure and change the current state of the cluster:
claccess
cldevice
cldevicegroup
clinterconnect
clnasdevice
clnode
clquorum
clreslogicalhostname
clresource
clresourcegroup
clresourcetype
clressharedaddress
clsetup
clsnmphost
clsnmpmib
clnsmpuser
cltelemetryattribute
cluster
clzonecluster
scdidadm
Records in the commandlog file can contain the following elements:
Date and timestamp
Name of the host from which the command was executed
Process ID of the command
Login name of the user who executed the command
Command that the user executed, including all options and operands
Note - Command options are quoted in the commandlog file so that you can readily identify them and copy, paste, and execute them in the shell.
Exit status of the executed command
Note - If a command aborts abnormally with unknown results, the Oracle Solaris Cluster software does not show an exit status in the commandlog file.
By default, the commandlog file is regularly archived once a week. To change the archiving policies for the commandlog file, on each node in the cluster, use the crontab command. See the crontab(1) man page for more information.
Oracle Solaris Cluster software maintains up to eight previously archived commandlog files on each cluster node at any given time. The commandlog file for the current week is named commandlog. The most recent complete week's file is named commandlog.0. The oldest complete week's file is named commandlog.7.
