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
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).
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.
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.
