Page: 32 / 64

Notes:
v
For the following operating systems, this must be a RAID configuration: AIX, Linux
v
You must have a minimum of one disk drive per hard-disk-drive partition.
1) Set the hard-disk-drive partitions switch to position 2. The hard-disk-drive partitions switch is
located at the rear of the 5802 expansion unit, just below the SAS connectors.
2) Choose one of the following SAS adapter and cable combination options:
v
Two FC ESA1 adapters (PCIe2 RAID SAS Dual-port 6 Gb) cabled with four FC 3689 cables
(AT 0.6 meter - HD SAS)
v Two FC 5805 or FC 5903 adapters (PCIe Dual - x4 3 Gb SAS RAID) cabled with four FC 3688
cables (AT 0.6 meter - Mini SAS)
v
Two FC 5901 adapters (PCIe Dual - x4 SAS) cabled with four FC 3688 cables (AT 0.6 meter -
Mini SAS)
Note: Dual FC 5901 adapters are not supported in IBM i.
v
Two FC 5913 adapters (PCIe2 1.8 GB cache RAID SAS Tri-port 6 Gb) cabled with four FC
3689 cables (AT 0.6 meter - HD SAS)
Note: The top ports of the FC 5913 pair must attach by an HD SAS AA cable.
3) Attach an AT cable (B) from the same numbered port on each SAS adapter (A) of a dual SAS
adapter pair to SAS connectors 1 and 2 on the 5802 SAS conduit card (C) , as shown in the
following figure.
4) Attach an AT cable (B) from other same numbered ports on the same adapter pair (A) to SAS
connectors 3 and 4 on the 5802 SAS conduit card (C) .
5)
Go to step 1i on page 25.
c. Complete the following steps to cable a configuration that includes one hard-disk-drive partition,
18 disks, and one SAS adapter.
1) Set the hard-disk-drive partitions switch to position 1. The hard-disk-drive partitions switch is
located at the rear of the 5802 expansion unit, just below the SAS connectors.
2) Choose one of the following SAS adapter and cable combination options:
v
One FC ESA1 adapter (PCIe2 RAID SAS Dual-port 6 Gb) cabled with one FC 3689 cable (AT
0.6 meter - HD SAS)
v
One FC 5901 adapter (PCIe Dual - x4 SAS) cabled with one FC 3688 cable (AT 0.6 meter -
Mini SAS)
