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 address of the adapter that is connected to the 2104 must be
different from the addresses of the installed disk drive modules. When a second
adapter is connected to a 2104, the SCSI address of that adapter must be different
from the address of the first adapter and the addresses of the installed disk drive
modules.
Note: A similar valid configuration can have two adapters, each with one external
SCSI connector, instead of the adapter with two external SCSI connectors.
