• Are other devices, such as drives or other peripherals, on the same SCSI bus? If
so, try moving the tape drives with the Extenders to a separate SCSI bus
managed by their own host adapter.
• Is the tape drive being driven from an on-board SCSI host adapter? Move the
drive with the Extenders to a separate board within the system. This will ensure
that the drives are isolated on their own bus.
Issue:
Errors are still occurring after all the previous resolutions have been tried.
Resolution(s):
• Turn off Global Disconnect/Reselect on the host adapter. To do this, change
the settings on the host adapter card when using NT or Windows 95/98. For
Sun
®
Solaris

, use the following command in the /etc/system file.
Set scsi_options=Ox3F0 Turns off Global Disconnect/Reselect
Set scsi_options=Ox3F8 Turns ON Global Disconnect/Reselect
