PRIMECLUSTER Global Link Services Configuration and Administration Guide: Redundant Line Control Function 4.1 (for Solaris(TM) Operating System)

3.4.4 NIC switching mode

The procedure to change the configuration information, and the configuration information and the other information at the same time is as follows:

1. Stop the router/HUB monitoring function using "hanetpoll off" command. See "7.7 hanetpoll Command" for the detail.
2. Deactivate a virtual interface to change using a "stphanet" command. See "7.3 stphanet Command" for the detail.
3. Change the setup information and parameter. (This can be done when executing "hanetpoll on" command for changing the monitoring period, the number of monitoring times, the recovery monitoring period, the waiting time for cluster switching and a link-up.)
   See "7.7 hanetpoll Command" for the detail.
4. Deactivate temporarily all virtual interfaces set in NIC switching mode using a "stphanet" command, then reactivate them using a "strhanet" command. See "7.2 strhanet Command" and "7.3 stphanet Command" for the detail.
5. Start Router/HUB monitoring function to monitor the routers/hubs using "hanetpoll on" command.
   (Changes made to the monitoring period, the number of monitoring times, the monitoring recovery period, the waiting time for a cluster failover, and the waiting time for a link up are reflected when "hanetpoll on" command is executed.)
   See "7.7 hanetpoll Command" for the detail.

The procedure for enabling a change made on the monitoring information is as follows:

1. Stop the router/HUB monitoring function using "hanetpoll off" command. See "7.7 hanetpoll Command" for the detail.
2. Start Router/HUB monitoring function to monitor the routers/hubs using "hanetpoll on" command.
   (Changes made to the monitoring period, the number of monitoring times, the waiting time for a cluster failover, and the waiting time for a link up are reflected when "hanetpoll on" command is executed. For more information, refer to "changing configuration and additional information at the same time".)
   See "7.7 hanetpoll Command" for the detail.

The following lists the information that can be changed for NIC switching mode. No information can be changed besides the information listed below. Delete the concerned definition and add it again.

• Configuration definition information
  Use the "hanetconfig" command to change the following information. For information, see Section "7.1 hanetconfig Command".
  • Host name or IP address to be attached to a virtual interface or a logical virtual interface
  • A physical interface name for the virtual interface
  • An IP address or host name of the physical interface
• Standby patrol information
  Use the "hanetconfig" command to change the following information. For information, see Section "7.1 hanetconfig Command".
  • Local MAC address to be allocated to a standby NIC
  • Interface names to be bundled by a virtual interface
• Information of monitored remote system and parameters
  Use the "hanetpoll" command to change the following information. For information, see Section "7.7 hanetpoll Command".
  • Information on monitored remote system (primary monitored remote system IP address and secondary monitored remote system IP address)
  • HUB-to-HUB monitoring
  • Monitoring interval
  • The number of monitoring times
  • Cluster switching
  • Link up waiting time
• Use the "hanetparam" command to change the following information. For information, see Section "7.6 hanetparam Command".
  • Standby patrol monitoring interval
  • The number of constant standby monitoring prior to outputting message

When the Solaris zone is used

If you want to use a redundant physical interface of NIC switching in the Solaris zone, it is necessary to add the configuration as follows;

1. Stop the Solaris zone.
2. Stop the router/HUB monitoring function using "hanetpoll off" command.
3. Deactivate a virtual interface to change using a "stphanet" command.
4. Change the setup information and parameter. (This can be done when executing "hanetpoll on" command for changing the monitoring period, the number of monitoring times, the recovery monitoring period, the waiting time for cluster switching and a link-up.)
5. Change the network settings. For information on how to change the zone network settings such as virtual IP address, see "3.2.4 Zone setup for Solaris container".
6. Deactivate temporarily all virtual interfaces set in NIC switching mode using a "stphanet" command, then reactivate them using a "strhanet" command.
7. Start Router/HUB monitoring function to monitor the routers/hubs using "hanetpoll on" command.
8. (Changes made to the monitoring period, the number of monitoring times, the monitoring recovery period, the waiting time for a cluster failover, and the waiting time for a link up are reflected when "hanetpoll on" command is executed.)
9. Start the zone.

• Ensure to specify the same IP address configured in /etc/hostname."interface-name" when specifying physical IP address by "hanetconfig" command using '-i' or '-e' option. If you specify different physical IP address, it disturbs communication using physical interface because this IP address will overwrite the physical IP address specified with "hanetconfig" command when activating the virtual interface.
