Tests an RMS resource for a specified resource state. It can be used in scripts when a resource must achieve a specified state before the script can issue the next command. Does not require root privilege.
Starts the base monitor and the detectors for all monitored resources. In most cases, it is not necessary to specify options to the hvcm command.The base monitor is the decision-making module of RMS. It controls the configuration and access to all RMS resources. If a resource fails, the base monitor analyzes the failure and initiates the appropriate action according to the specifications for the resource in the configuration file.
Either displays the current RMS configuration or sends the current configuration to an output file. The output of the hvconfig command is equivalent to the running RMS configuration file, but does not include any comments that are in the original file. Also, the order in which the resources are listed in the output might vary from the actual configuration file.
Displays information about the current configuration for RMS resources. Does not require root privilege.
Display the resource information of all the nodes in RMS.
Gets debugging information about RMS on the local node.
Either saves old log files into a subdirectory whose name is the time RMS was last started, or, if invoked with the -d option, deletes old log files. In either case, hvlogclean creates a clean set of log files even while RMS is running.
Reinitializes the graph of an RMS user application on one or more nodes in the RMS configuration. Running scripts will be terminated, ongoing requests will be cleaned up, and information about previous failures will be purged.
Note
The entire graph is returned to its initial consistent state by this command, but it may also become an inconsistent state. Therefore, use this command for test purposes only, and never execute it on a production cluster system.
Provides an interface for changing the following RMS environment variables on the local node:
HV_RCSTART controls the automatic startup of RMS.
HV_AUTOSTARTUP controls the automatic startup of all applications.
For more information about these environment variables, see "Appendix E Environment variables".
Shuts down RMS on one or more nodes in the configuration. The base monitor on the local node sends a message to other online nodes indicating which node or nodes will be shut down.
Manually switches control of a userApplication or a gResource between SysNodes in the RMS configuration.
Provides general administration interface to RMS and performs the following administration tasks.
Dynamically setting logging levels
userApplication Offline
Clearing faulted resources
Stopping cluster nodes in the Wait state
Setting detector monitoring time periods
Setting maintenance mode, and so forth
Note
Setting high logging levels in hvutil can cause disk overflow if enabled for too long. See the section "F.4.1 Managing base monitor log levels" for more information.
