In a two-drive library, the second drive (Drive 2) should be connected
to the available FC420 SCSI port, creating a second SCSI bus. This fully
utilizes the FC420 Fibre bridge and maximizes the communication
bandwidth available to each tape drive.
When cabling M2500 libraries with three or more tape drives, you
need to know the type of tape drive installed in the library and the
data transfer rate of the SAN to determine the correct SCSI
configuration.
As with the one- and two-drive configurations, all Fibre-to-
Note:
SCSI cabling configurations must include the SCSI controller
so that SCSI commands intended for the robot are
successfully communicated.
