Fixing an intermittent error with multiple drives on a SCSI bus
Refer to the server's error logs to determine which tape drive is the source of the
problem:

– If the test runs successfully, replace the SCSI terminator first, then the
SCSI cable to that tape drive and interposer (if installed).
– If the test fails, replace the tape drive (see "Removing a SCSI tape drive
from an enclosure" on page 57).
v If the problem is with two or more tape drives, locate the first tape drive that
has the error and replace the SCSI cable that connects the tape drive and the
interposer (if installed).
