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.
