Using SCO ARCserve/Open with multiple SCSI adapters
If your system has tape devices attached to multiple
SCSI host adapters, the SCSI ID
numbers used by all the tape devices must be unique
or SCO ARCserve/Open will not be able
to access them.
NOTE:
Regardless of the number of host adapters in your system,
SCO ARCserve/Open only recognizes a total of
7 tape devices, using SCSI ID Numbers 0 through 6.
