Cluster attributes lists the cluster attributes.
List of operating system user account groups that have administrative privileges on the cluster. | |
If the local cluster cannot communicate with one or more remote clusters, this attribute specifies the number of seconds the VCS engine waits before initiating the AutoStart process for an AutoStart global service group. | |
Time period in minutes after which VCS backs up the configuration files if the configuration is in read-write mode. The value 0 indicates VCS does not back up configuration files. Set this attribute to at least 3. See Scheduling automatic backups for VCS configuration files. | |
The CID provides universally unique identification for a cluster. VCS populates this attribute once the engine passes an hacf-generated snapshot to it. This happens when VCS is about to go to a RUNNING state from the LOCAL_BUILD state. Once VCS receives the snapshot from the engine, it reads the file /etc/vx/.uuids/clusuuid file. VCS uses the file's contents as the value for the CID attribute. The clusuuid file's first line must not be empty. If the file does not exists or is empty VCS then exits gracefully and throws an error. A node that joins a cluster in the RUNNING state receives the CID attribute as part of the REMOTE_BUILD snapshot. Once the node has joined completely, it receives the snapshot. The node reads the file /etc/vx/.uuids/clusuuid to compare the value that it received from the snapshot with value that is present in the file. If the value does not match or if the file does not exist, the joining node exits gracefully and does not join the cluster. To populate the /etc/vx/.uuids/clusuuid file, run the /opt/VRTSvcs/bin/uuidconfig.pl utility. See Configuring and unconfiguring the cluster UUID value You cannot change the value of this attribute with the haclus -modify command. | |
Specifies the cluster's virtual IP address (used by a remote cluster when connecting to the local cluster). | |
This attribute is used for VCS notification; specifically, VCS sends notifications to persons designated in this attribute when an event occurs related to the cluster. | |
The number of seconds since January 1, 1970. This is defined by the lowest node in running state. | |
Indicates if VCS engine is to verify that replicated state machine is consistent. This can be set by running the | |
Indicates the state of the wide-area connector (wac). If 0, wac is not running. If 1, wac is running and communicating with the VCS engine. | |
Intervals counted by the attribute GlobalCounter indicating approximately how often a broadcast occurs that will cause the GlobalCounter attribute to increase. The default value of the GlobalCounter increment can be modified by changing CounterInterval. If you increase this attribute to exceed five seconds, consider increasing the default value of the ShutdownTimeout attribute. | |
The number of days after which the VCS engine renews its credentials with the authentication broker. For example, the value 5 indicates that credentials are renewed every 5 days; the value 0 indicates that credentials are not renewed. | |
Defines whether you can delete online resources. Set this value to 1 to enable deletion of online resources. Set this value to 0 to disable deletion of online resources. You can override this behavior by using the -force option with the hares -delete command. | |
Defines the options for the hastop command. The attribute can assume the following values: Enable—Process all hastop commands. This is the default behavior. Disable—Reject all hastop commands. DisableClusStop—Do not process the hastop -all command; process all other hastop commands. PromptClusStop—Prompt for user confirmation before running the hastop -all command; process all other hastop commands. PromptLocal—Prompt for user confirmation before running the hastop -local command; reject all other hastop commands. PromptAlways—Prompt for user confirmation before running any hastop command. | |
This counter increases incrementally by one for each counter interval. It increases when the broadcast is received. VCS uses the GlobalCounter attribute to measure the time it takes to shut down a system. By default, the GlobalCounter attribute is updated every five seconds. This default value, combined with the 600-second default value of the ShutdownTimeout attribute, means if system goes down within 120 increments of GlobalCounter, it is treated as a fault. Change the value of the CounterInterval attribute to modify the default value of GlobalCounter increment. | |
List of operating system user accounts that have Guest privileges on the cluster. | |
This attribute has two, case-sensitive values: none-hacli is disabled for all users regardless of role. commandroot-hacli is enabled for root only.
Note
The command | |
Controls the behavior of the HostMonitor feature. Configure this attribute when you start the cluster. You cannot modify this attribute in a running cluster. This attribute has the following possible values: ALL-The HostMonitor daemon logs messages engine log and to the agent log. HMAgentLog-The HostMonitor daemon does not log messages to the engine log; the daemon logs messages to the HostMonitor agent log. | |
Controls the locking of VCS engine pages in memory. This attribute has the following values. Values are case-sensitive: | |
Indicates the size of engine log file in bytes. Minimum value is = 65536 (equal to 64KB) | |
Indicates the status of the notifier in the cluster; specifically: State—Current state of notifier, such as whether or not it is connected to VCS. Host—The host on which notifier is currently running or was last running. Default = None Severity—The severity level of messages queued by VCS for notifier. Values include Information, Warning, Error, and SevereError. Default = Warning Queue—The size of queue for messages queued by VCS for notifier. | |
List of operating system user groups that have Operator privileges on the cluster. | |
Indicates the scheduling class for processes created by the VCS engine. For example, triggers. | |
The priority of processes created by the VCS engine, for example: triggers. | |
Indicates whether the cluster runs in secure mode. The value 1 indicated the cluster runs in secure mode. This attribute cannot be modified when VCS is running. | |
File from which the configuration is read. Do not configure this attribute in main.cf. Make sure the path exists on all nodes before running a command that configures this attribute. | |
The IP address and hostname of systems running the steward process. | |
Indicates whether the cluster uses I/O fencing. The value SCSI3 indicates that the cluster uses either disk-based or server-based I/O fencing; the value NONE indicates it does not. | |
Note
The installer program uses | |
Indicates which VCS features are enabled. Possible values are: 0—No features are enabled (VCS Simulator) 2—Global Cluster Option is enabled
