Multiple SMART-2DH Controller
Installation
When you install more than one SMART-2DH Array Controller in the same
server, the following considerations apply:
■
Each SMART-2DH Controller has two independent SCSI channels,
each of which supports up to seven drives.
■
Each SCSI channel has its own set of unique SCSI IDs (from 0 to 6).
You must assign each peripheral on the bus a unique ID for that bus.
Since only one of the two SCSI ports is available on its external connector, the
other internal port must be brought out to an external connector if it is to be
used for external storage. In some servers, a connector panel is provided for
this purpose, but in others the internal port is brought out through an unused
option slot using a special connector bracket.
