Object information on PDS

A PDS (Physical Device Server) controls precisely one physical device. The object infor-
mation displays the controller and target of the associated SCSI device. This information is
also indicated by the color of the connecting lines to the SCSI controllers and drives.

A PDS consists of two processes, one for communicating with the RAID system and the
other for communicating with the device. These processes are referred to as the channel
process and the device process. Normally, both processes have the same status. However,
there are situations in which this will not be the case. If this occurs, the top half of the block
shows the status of the channel process, while the bottom half shows the status of the
device process. The process status is indicated by the colors pink (stopped), green
(running), and green/brown (running with the trace switched on).
