The SCSI Bus Interface
2 SL500: Interface Reference Manual • July 2008 Revision: F • 96122
The library supports SCSI-3 commands using LUN 0.
The library and the tape drives have separate connections for attachment to the
SCSI bus. Daisy-chain cables are available to interconnect devices on the SCSI bus
but keep the total cable length to a minimum. FIGURE 1-1 is an example of a
library and four tape drives that are daisy-chained to two initiators (or hosts).
Note – It is recommended that the drives be connected to a separate SCSI bus from
the library.
