Disk Subsystems Cabling Requirements
EPC400 Node
A multi–port asynchronous board is not appropriate. A serial port is suitable for the DAS
management through a serial line.
DAS Management Through SCSI Links
In any case, DAS management can be performed thru SCSI links from nodes the DAS
subsystem is attached to, by using the Navisphere application from a graphical terminal.
The remote maintenance option consumes the S2 serial port on a node when an external
modem is connected to that node. A serial line is mandatory to manage the DAS the first
time (to bind the first LUN). So this may enter in conflict with the need of serial ports for
heartbeat line establishment, for system console and for remote maintenance. Therefore a
graphical terminal (a graphics display, an X terminal or a PowerConsole) is recommended
for the management of the DAS.
