IBM TotalStorage DS4000: Hardware Maintenance Manual
Note: Power cycling the SDG Router does not re-instate it to normal mode
if previously set to diagnostic mode. Use normalBoot command
(page 128) to re-initialize the router to normal mode.
The diagHelp command displays a list of the diagnostic commands.
Router > diagHelp .
The following commands are available in diagnostic mode only.
ddfTest: Test DDF Memory
elTest: Test Ethernet port w/loop-back cable
fcSlotTest <portnum> : Test specified fibre channel port w/loop-back cable
hardwareConfig: Re-inventory FRUs and update Vital Product Data
normalBoot: Shutdown and restart in normal mode
scsiChannelTest <x,y>: Test specified SCSI Channels w/loop-back cable
The fcShow command displays the channel status for the fibre channel
interface.
The following example is for an SDG Router single-port fibre channel PMC
card (ISP2200 controller). The firmware state for interfaces that have a live
connection to a fibre channel device are shown as Ready. An interface that
has no live connection shows as Sync Lost.

The following list describes the example fields:
Ctlr ID The channel number for this interface
PCI Addr The PCI address of the interface, showing bus, device ID, and
function number
ISPType The type of fibre channel controller, ISP2100 or ISP2200
Firmware State The current state of the interface as reported by the fibre
channel PMC adapter firmware. The firmware states are:
v Configuration Wait: Firmware is not initialized.
v Waiting for AL_PA : Firmware is performing or waiting to perform loop
initialization.
v Waiting for login: Firmware is attempting port and process logins with
all loop ports.
v Ready: Indicates that the interface is connected, operational and ready to
process SCSI commands. Any other value indicates intermediate states
or interface failure.
