Configuring Paths for Tape Devices
Configuring Paths for Tape Devices
The values you specify when configuring a tape device depend on the type of
connection and the NonStop server model. For example, the valid ranges for group,
module, and slot of a tape device connected to an FCSA on an Integrity NonStop
NS-series server differ from those of a tape device connected to an IOMF CRU on a
NonStop S-series server.
Table 13-1, Tape Device Path Attributes, on page 13-2 lists the possible attribute
values for the different types of tape device paths.
Fibre Channel Tape Connections
To configure tape drives that are connected to the system through an FCSA follow
these rules:
•
If a Fibre Channel tape drive is connected directly to an FCSA, you must specify
the PORTNAME and LUN of the tape drive.
•
If the tape drive is connected to an FCSA through an M8201 SCSI to Fibre
Channel router, you must specify the PORTNAME and LUN associated with the
M8201 port to which the tape drive is connected. For details, see the M8201 Fibre
Channel to SCSI Router Installation and User’s Guide.
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 NonStop
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.
