Figure 33. Two Adapters in One Non-HACMP Using System Connected to One 2104 (Dual-Bus Mode)

1	SCSI interface card
2	SCSI or SCSI RAID adapter of one of these types:
	v PCI SCSI-2 Single-Ended Fast/Wide Adapter (type 4-A, feature 6208)
	v PCI Single-Ended Ultra SCSI Adapter (type 4-K, feature 6206)
	v PCI Dual-Channel Ultra2 SCSI Adapter (type 4-R, feature 6205)
	v PCI Dual-Channel Ultra3 SCSI Adapter (type 4-Y, feature 6203)
	v PCI 3-Channel Ultra2 SCSI RAID Adapter (type 4-T feature 2494)
	v PCI 4-Channel Ultra3 SCSI RAID Adapter (type 4-X, feature 2498)
	Note: Connection can be to an integrated SCSI port instead of to a SCSI connector
	on one of the listed SCSI adapters

Attention: This 2104 configuration is supported on the Linux for pSeries operating

system when attached to the host with the PCI Dual-Channel Ultra3 SCSI Adapter

(type 4–Y, feature 6203).

Attention: The SCSI addresses of the adapters that are connected to the 2104

must be different from each other and from the addresses of the installed disk drive

modules.

Note: A similar configuration that has one adapter with two external SCSI

connectors, instead of the two single-connector SCSI adapters, is also a

valid configuration.
