Single-bus mode configurations
For a single-bus mode configuration, you must set the SCSI bus split switch on the
card of a 2104 Model TS4 to off.
You can connect each 2104 Model TS4 to one external SCSI connector on a SCSI
adapter card, or to one integrated SCSI port, in a host system. If an adapter card
has four external SCSI connectors, you can connect it to up to four 2104 Model
TS4s.
For High Availability Cluster Multi-Processing (HACMP) configurations, you can
connect the two SCSI interface cards in a 2104 Model TS4 to external SCSI
connectors on adapter cards or to integrated Ultra2 SCSI ports, in two different host
systems. The adapter cards must be a PCI Dual-Channel Ultra3 SCSI Adapter (type
number 4-Y, feature code 6203) or PCI-X Dual Channel Ultra320 SCSI adapter
(type number 5702, feature code 5812).
For non-HACMP configurations, you can connect the SCSI interface cards in a
2104 Model TS4 to an external SCSI connector on an adapter card or to an Ultra2
SCSI integrated port in a host system. Each adapter must be a PCI Dual-Channel
Ultra3 SCSI Adapter (type number 4-Y, feature code 6203) or PCI-X Dual Channel
Ultra320 SCSI adapter (type number 5702, feature code 5712). The adapters must
be in two different host systems. They must not share access to the disk drives in
the 2104 Model TS4.
