Serial Connections
Promise products use a serial connection for a command line utility (CLU).
Normally, users prefer WebPAM because of its graphic user interface. But the
CLU can do most of the same jobs. And it will work when your SCSI chain or
network connection is down.
For VTrak, you must use the CLU to set the RAID subsystem's initial IP address
in order for WebPAM to connect with it. This issue is discussed further under
Network Connections (below).
The CLU controls and manages but it does not move data. It communicates
through a null-modem cable, supplied with the Promise product. You can connect
a straight-through serial cable, but it will not work for this purpose. If you do not
use the CLU often, you might want to disconnect and store the cable. Consider
leaving it connected, to be sure it will be there when you need it.
Network Connections
The UltraTrak has an RJ-45 connection on the back of its cabinet. This looks like
a network connector, but it is actually wired as an alternative serial connector for
the CLU. UltraTrak does not connect directly to a network, it goes through the
Host/RAID PC. As mentioned above, UltraTrak uses In-Band SCSI technology
for command and monitoring.
The VTrak also has an RJ-45 connector on the back of its cabinet. This connector
is a genuine 1000/100/10BaseT connector designed to connect to your network.
The VTrak becomes a node on your network like any other PC, server or other
component with an IP address. VTrak ships from the factory an IP address of
10.0.0.1. You must change this address to one that will work with your network.
You make the initial IP address setting using the CLU, as mentioned above. You
can make subsequent IP address changes using WebPAM.
Note that VTrak does not accept IP address assignments from a DHCP server. If
you have a DHCP server on your network, there is a chance that it will
inadvertently assign the VTrak's IP address to another node. You might see a
warning to this effect on your PC's monitor. If this happens, WebPAM may not be
able to connect. See your IT administrator to work out a suitable arrangement.
