notes for the PCI-X Double-Wide, Quad-Channel Ultra320 SCSI RAID Controller
for IBM® System i® models.
The PCI-X Double-Wide, Quad-Channel
Ultra320 SCSI RAID Controller is a high-performance SCSI adapter
combined with an auxiliary-write cache adapter to form a double-wide,
adapter pair. The two adapters are screwed together.
Features
- 3 external U320 SCSI ports
- 1 internal U320 SCSI port dedicated to connecting the controller
to the auxiliary-write cache adapter
- Up to 36 Direct Access Storage Devices (DASD) can be externally
attached per adapter
- 320 MB/s data rate per SCSI bus
- Supports low voltage differential (LVD) disk devices only
- Supports RAID 5 and 6 (3–18 drive sets)
- 390 MB/1.5 GB compressed write cache
- 415 MB/1.6 GB compressed read cache
- PCI-X DDR support (storage adapter side)
- IOP or IOPless (5739 requires an IOP. 5778 does not.)

| Unit description |
- 64 bit, 133 MHz, 3.3 V
- Peripheral Component Interconnect-X (PCI-X) 2.0 compliant
- Double-wide adapter, requires 2, adjacent, long slots. The SCSI
controller side of the adapter pair requires a 64 bit slot. (The controller
side is the side with the external SCSI connectors.)
- The auxiliary-write cache adapter contains a dual, concurrently
maintainable, cache-battery pack, which maintains cache memory on
both adapters in the event of an abnormal termination.

Placement information
For placement information for these adapters, see
the PCI adapter placement for machine type 94xx or PCI adapter placement for machine types 82xx and 91xx including
the section High-end SCSI controller placement.
Logical partitioning
When used
in a logical partition (LPAR) environment, this double-wide adapter
must have both slots of the adapter assigned to the same logical partition.
When implementing dynamic LPAR (DLPAR), both slots of the adapter
must be managed together.
Installing the adapter
in a cassette
To install this adapter in a cassette, first
remove the adapter handle (B), and the two
plastic covers from the SCSI jumper cable (A),
as shown in the following figure.

adapter for placement in a cassette
Power LED
For a double-wide
adapter, there is only one power LED visible for both slots.
Concurrent maintenance
procedure
Concurrent maintenance of this adapter
is not supported through the Hardware Management Console (HMC). Concurrent
maintenance must be initiated from the Hardware Service Manager (HSM)
of the system or owning partition. The HSM automatically turns off
the power of both PCI slots when either slot is selected.
Important: - Both PCI slots must be powered off when installing or removing
this adapter with the system power turned on.
- If this adapter is the load source IOA, or under the load source
IOP, or any other storage IOA/IOP with critical DASD attached for
the system, the system may temporarily hang until this procedure
is completed (the slots are powered back on and the adapter has become
operational again). In this configuration, this concurrent maintenance
procedure must be done by a qualified service provider. At step 12, the HSM directs you to use
the control panel functions 68 and 69 to turn off the power or turn
on the power on the domain.
Follow this procedure:
- Start an IBM i operating
system session for the system or logical partition that contains the
adapter, and sign on to the system or logical partition.
- Type strsst on the command line of the
Main menu and then press Enter.
- Type your service tools user ID and service tools password on
the System Service Tools (SST) Sign On display and press Enter.
- Select Start a service tool from the System
Service Tools (SST) display and press Enter.
- Select Hardware service manager from the
Start a Service Tools display and press Enter.
- Select Logical hardware resources (system, frames,
cards) from the Hardware Service Manager display and press
Enter.
- Select System bus resources and press Enter.
The display changes to the Logical Hardware Resources on System Bus
display.
- Page down and locate Combined Function IOP that
controls the IOA to be serviced.
- Enter 9 in the Opt field for the Combined Function
IOP to be serviced.
- Locate the Storage IOA resource for the
adapter to be serviced and enter 8 in the Opt field for that resource.
- Enter 3 for Concurrent maintenance in the
Opt field for the Storage IOA resource to be
serviced. The display changes to the Hardware Resource Concurrent
Maintenance display.
- Press F9 to turn off the power to the domain.
- Press Enter to confirm start turning off the power. The display
changes to the Hardware Resource Concurrent Maintenance Status display,
which shows the status of the turned off power.
When the power is
turned off completely, the display returns to the Hardware Resource
Concurrent Maintenance display. The display shows that the Power
Status is turned off for Storage IOA.
Leave this display on the HSM while you remove and replace the adapter.
- Check the slot power LED state for the slot in which the adapter
is placed to verify that power of the adapter is turned off.
For
a double-wide adapter, there is only one power LED visible for both
slots.
- Remove and replace the adapter. Removal
and replacement procedures are detailed in Installing PCI adapters.,
- After the replacement is complete, return to the Hardware Resource
Concurrent Maintenance display on the HSM.
- If you were previously instructed to use operator panel function
69 to power on the adapter, do so now from either the system operator
panel or from the HMC operator panel functions for the owning partition.
Then go to step 22, otherwise
continue with next step.
- Enter F10 to turn on the power to the adapter.
- Press Enter to begin turning on the power.
- If the Work with Controlling Resource display is shown, enter
7 in the Opt field for the Combined function IOP to
assign the IOA.
The Hardware Resource Concurrent Maintenance Status
display shows the status of the power turned on.
- When the power is turned on completely, the display returns to
the Hardware Resource Concurrent Maintenance display. The display
shows that the Power Status is turned on for
the Storage IOA.
- Check the LED status to verify that the adapter
power is turned on.
For a double-wide adapter, there is only one
power LED visible for both slots.
- Return to the procedure that sent you here.
