SCSI SWITCH (FOR AS/400
®
)
4. Configuring and Operating
the SCSI Switch
4.1 Configuring the SCSI Switch to the AS/400
The following procedures must be performed on one AS/400 at a time.
When configuring the drives and the SCSI Switch to the second AS/400,
all associated controllers and devices must be varied off on the first AS/400.
Failure to do this will cause configuration errors on the second AS/400.
We recommend that you turn OFF Auto-Configure and manually
create the controller and device descriptions.
1. Power off both AS/400 hosts.
Use the following command to end all systems.
endsbs *all *immed
When all subsystems have ended enter the following:
pwrdwnsys *immed
2. Install the tape drive and the SCSI Switch.
3. Power on one of the AS/400 hosts.
4. Create the controller description.
Once the AS/400 completes the IPL, sign on as user QSECOFR.
At the command line, enter the command
dsplclhdw
. Scroll through
the local hardware screens and identify the 6790E/3490E that was just
installed. Locate the resource name associated with the controllers.
This resource name will be used when configuring the controller description.
Press F3 to return to the command line.
Enter the command
crtctltap
and press F4. This will display
the Create Controller Description screen.
Enter the required parameters to create the controller description.
