Nomadic Disk Software
Nomadic Disk Manager
The Nomadic Disk Manager is an independent product that provides a TACL
environment designed to reduce the complexity of managing a ServerNet Nomadic Disk
environment. Nomadic Disk Manager requires the following software:
•
ServerNet Nomadic Disk switch command interface (SWCI), used to communicate
with the ServerNet Nomadic Disk switch modules.
•
The DefineProcess product, a component of ViewPoint (ViewPoint itself is not
required). The DefineProcess directory, :UTILS:DP, must be in the #USELIST of
the TACL process.
Switch Command Interface (SWCI)
You can use the ServerNet Nomadic Disk switch command interface (SWCI) utility to
communicate with and control a switch module from a server.
SWCI requests information about the switch module or changes the state of individual
switches. SWCI sends each command to the switch controller card (SCC) of the switch
module and then reports the results of the command execution back to you. The SCC
controls all switch cards in the switch module. The SWCI software is located on the
$SYSTEM.SYSnn subvolume.
