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

3.5.4 NIC switching mode

The following shows the procedure for deleting configuration information:

1. Use the "hanetpoll off" command with '-n' option to stop the HUB polling feature of the virtual interface targeted for deletion. This command, "hanetpoll off" with '-n' option allows you to stop the virtual interface by specifying them individually. For information, see Section "7.7 hanetpoll Command".
2. Inactivate the virtual interface of the concerned NIC switching mode using the "stphanet" command. To delete the operated definition in a cluster system, deactivate a virtual interface of the standby patrol using the "stpptl" command (only when using a standby patrol function). For information, see Section "7.3 stphanet Command" and Section "7.11 stpptl Command".
3. Delete the concerned monitoring destination information. For information, see Section "7.7 hanetpoll Command".
4. Delete the configuration information of the concerned virtual interface. For information, see Section "7.1 hanetconfig Command".
5. When IPv4 address is being used, the corresponding /etc/hostname.interface file is deleted and the host name further defined as the /etc/inet/hosts file is deleted.
   When IPv6 address is being used, the corresponding /etc/hostname6.interface file is deleted and the host name further defined as the /etc/inet/ipnodes file is deleted.

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. Use the "hanetpoll off" command with '-n' option to stop the HUB polling feature of the virtual interface targeted for deletion. This command, "hanetpoll off" with '-n' option allows you to stop the virtual interface by specifying them individually.
3. Inactivate the virtual interface of the concerned NIC switching mode using the "stphanet" command.
   If the logical IP address takeover function is set, disable a virtual interface of standby patrol using the "stpptl" command. (only for standby patrol)
4. If you cancel network high-reliability through NIC switching in all zones, return the method of deactivating a standby interface to "unplumb" using the "hanetparam -d" command. If you continue network high-reliability through NIC switching in the other zones, do not return the method of deactivating a standby interface to "unplumb".
5. Delete the concerned monitoring destination information.
6. Delete the configuration information of the concerned virtual interface.
7. When IPv4 address is being used, the corresponding /etc/hostname.interface file is deleted and the host name further defined as the /etc/inet/hosts file is deleted.
   When IPv6 address is being used, the corresponding /etc/hostname6.interface file is deleted and the host name further defined as the /etc/inet/ipnodes file is deleted.
8. Delete the zone or change the zone network settings. For information on how to change the zone network settings or delete the zone, see "3.2.4 Zone setup for Solaris container".
