Three adapters in two non-HACMP host systems connected to
two 2104 Model TS4s
Figure 39 shows three adapters in two non-HACMP host systems connected to two
2104 Model TS4s (dual-bus mode).

SCSI interface card.

SCSI or SCSI RAID adapter of one of these types:
v
PCI Dual-Channel Ultra3 SCSI Adapter (type number 4-Y, feature code 6203)
v
PCI 4-Channel Ultra3 SCSI RAID Adapter (type number 4-X, feature code 2498)
v
PCI-X Dual Channel Ultra320 SCSI adapter (type number 5702, feature code
5712)
Important: An RS/6000 or IBM
Eserver
pSeries computer running Linux for
pSeries uses the following to connect to the 2104 Model TS4.
v
PCI 4-Channel Ultra3 SCSI Adapter (type number 4-Y, feature code 6203)
v
PCI-X Dual Channel Ultra320 SCSI Adapter (type number 5702, feature code
5712)
v
PCI-X Dual Channel Ultra320 SCSI RAID Adapter (type number 5703, feature
code 5703)
Note: The connection can be to an integrated SCSI port instead of to a SCSI
connector on one of the listed SCSI adapters.
Notes:
1. The SCSI address of the adapter that is connected to the 2104 Model TS4 must
be different from the addresses of the installed disk drive modules. The SCSI
address of a second adapter, which is connected to a 2104 Model TS4, can be
the same address of the first adapter but must be different from the addresses
of the installed disk drive modules on the same SCSI bus.
2. A similar valid configuration can have two adapters, each with one external
SCSI connector, instead of the adapter with two external SCSI connectors.
