The hanetparam command sets up the monitoring function when the Fast switching operation or the standby patrol function is used. This command also changes the method of activating and inactivating Fast switching mode and NIC switching mode.
You can specify the following options:
Specify the interval (value) for monitoring the communication target in Fast switching mode. A value from 0 to 300 can be specified. No monitoring is performed if 0 is specified in value. By default, 5 is specified. This parameter is enabled only for Fast switching mode.
Specify the monitoring retry count (value) before message output when the message output function for a line failure is enabled.
Specify the monitoring retry count (value) before message output. A value from 0 to 100 can be specified. No message is output if 0 is specified in value. By default, no message is output. This parameter is enabled only for Fast switching mode.
Specify the cluster failover function.
Specify how many times (count) communication with the communication target can fail consecutively before cluster failover is performed. A value from 0 to 100 can be specified. No cluster failover is performed if 0 is specified in value. When performing cluster failover, the number of times for repeating surveillance is specified in the range from 1 time to 100 times until it cluster failover. By default, cluster failover is specified to be performed if communication fails five consecutive times. This parameter is enabled only for Fast switching mode on a cluster system.
When operating Fast switching mode on a cluster system and when an error occurred in all transfer routes at the activation of a userApplication, sets if or not to execute failover between clusters (job switching between nodes).
Specify "on" to value for executing failover between clusters (job switching between nodes) when an error occurred in all transfer routes at activation of a userApplication.
Specify "off" to value for not executing failover between clusters when an error occurred in all transfer routes at activation of a userApplication.
"off" is set to value as an initial setting value.
Specify if or not to output a message when a physical interface, which a virtual interface uses, changed the status (detected an error in a transfer route or recovery). A value possible to specify is "on" or "off". When specified "on", a message is output (message number: 990, 991, and 992). When specified "off", a message is not output. The initial value is "off". This parameter is valid only in fast switching mode.
Specify the interval (value) for monitoring the communication target when the standby patrol function is enabled. A value from 0 to 100 can be specified. No monitoring is performed if 0 is specified in value.
Do not specify 0 to this parameter when set a user command execution function (executing a user command when standby patrol detected an error or recovery). User command execution does not function if specified 0.
By default, 15 is specified. This parameter is enabled only for NIC switching mode.
Specify the monitoring retry count (value) before message output when the message output function for a standby patrol failure is enabled.
Specify the monitoring retry count (value) before message output. A value from 0 to 100 can be specified.
When specified 0, stop outputting messages and make monitoring by a standby patrol function invalid. Do not specify 0 to this parameter when set a user command execution function (executing a user command when standby patrol detected an error or recovery). User command execution does not function, if specified 0.
By default, 3 is specified. This parameter is enabled only for NIC switching mode. The number of the times of continuous monitoring is "a set value of this option x 2" immediately after started standby patrol.
Use this parameter to change the method of inactivating the standby interface in NIC switching mode. Specify "plumb" in value to inactivate the standby interface and set "0.0.0.0" as the IP address. This procedure allows "INTERSTAGE Traffic Director", etc. to be used as the host application. Alternatively, specify "unplumb" in value to inactivate and delete the standby interface. Initially, "unplumb" is specified in value. If you specify a physical interface of NIC switching for the network setting of the Solaris container (zone), be sure to specify "plumb" for the parameter. If the Solaris zone is started without the "plumb" setting, Solaris zone startup will fail because the physical interface (standby interface) has not been used. Specifying "plumb" will deactivate the standby interface after NIC switching so that zone startup will properly be performed.
