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.
