Defined:
This message usually occurs
when the ASR-10 is trying to
access the floppy drive or a
removable SCSI Storage
Device when there is no disk or
cartridge in the drive.
The disk (or cartridge) has
been ejected from the drive
since the last time the drive
was accessed bv the ASR-10.
If encountered while using a
SCSI Storage Device, this error
may indicate a problem with
your SCSI cables. The cable
from the ASR-10 to the Storage
Device may be too long, or the
system may not have proper
termination.
No SCSI device with this ID
was connected to the network
when the ASR-10 booted UD.
The SCSI device selected is
not an ASR-10 formatted
storage device, and cannot be
used by the ASR-10.
A SCSI device that was
detected by the ASR-10 at
bootup is no longer connected
or turned on.
Final Thoughts
What to Do:
If this message occurs, insert a floppy disk or
cartridge in the drive, then use the CHANGE
STORAGE DEVICE Command to select the
a ro riate SCSI ID number (or press
B
LOAD , then (INSTRUMENTJ. This event may
take place because of improperly saved files.
Refer to the section on “Transferring Banks
pe;c;.floppy Disk to a SCSI Storage
Reinsert the disk or cartridge, press (LOAD),
then (INSTRUMENT), and continue.
Check all connections and make sure that you
are using the correct cables. Make sure you
have the proper termination. If this message
appears repeatedly while files are being saved
to the disk, then it is likely that you are
invisibly losing sectors of your disk. Correct
the problem before continuing to use the disk.
Use the CHANGE STORAGE DEVICE
Command to verify that you are using the
correct SCSI Device number.
You may choose to reformat the SCSI
Storage Device for use with the ASR-10. Use
caution, as this will erase all previously saved
data on the SCSI Storaae Device.
Check your SCSI connections. If your SCSI
Storage Device has a changeable ID number,
make sure it matches the SCSI Device
Number you have chosen in the CHANGE
STORAGE DEVICE Command.
The main problems that you are likely to encounter are the SCSI Storage Device problems
described above and cable problems. These are some additional recommendations to help
eliminate many problems:
1.
Use the shortest cable possible when connecting SCSI Storage Devices.
2 Be sure to use proper termination. Refer to the SCSI Terminators section of this manual.
3.
If you need to use an extension cable between your ASR-10 and your SCSI storage device(s),
use high quality shielded SCSI extension cables only (do not use printer cables).
4.
Avoid running SCSI cables across power cables and other sources of powerful
electromagnetic fields.
5.
It is required that the SCSI Storage Device supply power to the SCSI bus. Check your SCSI
Storage Device manual for further information.
6.
Some SCSI Storage Devices may have their SCSI Device ID number set internally. Refer to
the SCSI Storage Device’s manual or manufacturer for more information.
7.
If you use an Apple computer in your setup, be sure to use a short (18” or shorter) Apple-
brand SCSI cable between the computer and the first connected SCSI Storage Device.
Remember, most of the problems we encounter are with cabling or with systems that are not
terminated properly. If you encounter a problem, make sure you have checked these things
carefully before assuming that your ASR-10,
SF’-3
or your SCSI Storage Device are at fault.
