Operating Configurations of Dedicated Service LANs
Multiple System Consoles Managing Multiple Systems
The servers must have fault-tolerant connections to the Ethernet switches or hubs. In
addition, the system consoles and the servers must be on the same subnet. If a server
is configured to receive dial-ins, the server must occupy the same subnet as the
system console receiving the dial-ins.
For best OSM or TSM performance, no more than 10 servers should be included within
one subnet.
Because all servers are shipped with the same preconfigured IP addresses for MSP0,
MSP1, $ZTCP0, and $ZTCP1, you must change these IP addresses for the second
and subsequent servers before you can add them to the LAN.
You must change the preconfigured IP addresses of the second and subsequent
system consoles before you can add them to he LAN.
