To use all host names and IP addresses used in a Redundant line Control Function , they must be defined in /etc/hosts files of the local system
The system automatically determines the length of MTU for an interface. Nonetheless, it is possible to change the length of MTU using user command execution function. For changing MTU length, refer to "3.12.2 Setting user command execution function". Note that the length of MTU cannot be modified in NIC switching mode.
Multicast IP addresses cannot be used.
An IPv6 over IPv4 tunneling interface (sitX) is not supported.
If a user individually activates or deactivates virtual interfaces registered in the cluster, the interface status monitoring feature restores them to their original state on the operation.
It is not possible to use DHCP (a server function and a client function) as the upper application.
If you use GS linkage mode, be sure to set up the remote host monitoring function. For information on how to do this, see "7.15 hanetobserv Command".
If you use GS linkage mode, be sure to set up the virtual gateway. For information on how to do this, see "7.14 hanetgw Command".
GS linkage mode is not available for communications between a Linux server and a Solaris server.
Do not set the same virtual IP address on GS for the communication target, if you set multiple GLS's takeover virtual IP addresses within the same cluster. You can do this between different clusters.
Set a different network address from the virtual IP address of the communication target GS for a virtual IP address in GS linkage mode.
Set the virtual IP addresses used in GS linkage mode to have different network addresses.
When communicating between GLS and GS via router, make sure that the router neighboring GLS is RIPv1 and the path to GS's virtual IP address is broadcast.
In GS linkage mode, set the same netmask for the virtual IP addresses of GS and GLS, and physical IP addresses.
In GS linkage mode, the tagged VLAN function is not available.
If a TNOTIFY is executed to GLS from GS, GLS returns the processing result 80.
When using the logical virtual IP address of GS linkage mode as a source, it is necessary to fix the logical virtual IP address to be the source on the application side with the bind function.
