In GS/SURE linkage mode, the system uses duplicated paths concurrently but it cannot be expected to improve the throughput.
Be sure to set a function to monitor the other side to communicate when using GS/SURE linkage mode. See "7.5 hanetobserv Command" as to how to set.
In GS/SURE mode, data communication with SPARC Servers, PRIMEPOWER, GP7000F, Fujitsu S series, GP-S, PRIMERGY, or PRIMEQUEST is not possible.
In GS/SURE linkage mode, the route to the virtual IP address of the destination system is recognized by using the RIP protocol. Set the RIP advertisement on the GS/SURE system (destination system). In this mode, RIPv1 is supported.
In GS/SURE linkage mode, communication with up to four hosts is possible. Communication with the fifth host or later is not possible.
It is not possible to operate under the subnet environment of the variable length in GS/SURE linkage mode. The same value must be assigned to all subnet masks for virtual interfaces.
Only one connectable NIC interface is provided on a single network for the local system. Multiple interfaces cannot be connected on the same network.
When using LR, CLCU, or LANC2 as the LAN adapter for the global server PRIMEFORCE, use "channel embedded system."
When using GS/SURE linkage mode, you must specify the definition to use the following functions for the network definition of VTAM-G TISP on the global server PRIMEFORCE:
Connection function with LAN duplication
Recovery function from network failure
Recovery function from host failure (Hot standby by dynamic switching of the system address)
For details on definition, see "OSIV VTAM-G TISP Handbook."
Do not connect to other servers between the local system and the remote system (GS server/ SURE SYSTEM) in GS/SURE linkage mode.
For GS Hot-standby, the node that received the down notification by the TNOTIFY command from GS is recognized as the communication target.
If a TNOTIFY command is executed to GLS from GS, GLS returns the processing result 80.
