Configuring Paths for Open SCSI Devices
Configuring Paths for Open SCSI Devices
The values you specify when configuring an Open SCSI device vary depending on the
type of connection and the NonStop server model. For example, the valid ranges for
group, module, and slot of an Open SCSI device connected to an FCSA on an Integrity
NonStop NS-series server differ from those of an Open SCSI device connected to an
ServerNet/DA on a NonStop S-series server.
Table 12-1, Open SCSI Path Attributes, on page 12-2 lists the possible attribute values
for the different types of Open SCSI connections.
Note. When a NonStop S-series I/O enclosure is attached to an Integrity NonStop NS-series
system, the enclosure retains the same group number it had on the NonStop S-series system.
However, if the appropriate port for the group number is not available on the Integrity NS-series
server, you must change the group number of the I/O enclosure. For more information, see the
NonStop NS-Series Hardware Installation Manual.
