ATTO Technology Inc. Diamond Storage Array Installation and Operation Manual

5.5.4 Fibre Channel Configuration Commands

The Fibre Channel ports are configured with default settings but may be customized to your
specifications using the CLI commands in this section.

FcConnMode
Specifies the Fibre Channel topology for the Diamond
Storage Array. Options are loop only (loop), point-to-
point only (ptp), loop preferred (loop-ptp) or point-to-
point preferred (ptp-loop). Refer to Connecting a Fibre
Channel Array
on page 11 for more information on Fibre
Channel topology. Applies to both Host Interface Cards.

Default: loop
Set syntax: set FcConnMode [loop | ptp| loop-ptp| ptp-
loop]
Requires a SaveConfiguration command
Get syntax: get FcConnMode

FcDataRate
Specifies the Fibre Channel data rate at which the
Diamond will operate. Applies to both Host Interface
Cards.

Default: auto
Set syntax: set FcDataRate [1gb | 2gb | auto]
Get syntax: get FcDataRate
Requires a SaveConfiguration command

FcFairArb
Enabling this feature causes the Diamond Storage Array
to follow the arbitration fairness rules on the FC-AL.
Applies to both Host Interface Cards.

Default: enabled, enabling arbitration fairness
Set syntax: set FcFairArb [enabled | disabled]
Get syntax: get FcFairArb
Requires a SaveConfiguration command

FcFrameLength
Sets the frame length of a command. If not specified in
the set command, current frame length is displayed.
Applies to both Host Interface Cards.

Default: 2048
Set syntax: set FcFrameLength [512 | 1024 | 2048]
Get syntax: get FcFrameLength
Requires a SaveConfiguration command

FcFullDuplex
Enable to allow full duplex Fibre Channel
communication between the Diamond Storage Array and
host devices. Disable FcFullDuplex causes half duplex
mode.Applies to both Host Interface Cards.

Default: enabled
Set syntax: set FcFullDuplex [enabled | disabled]
Requires a SaveConfiguration command
Get syntax: get FcFullDuplex

FcHard
If hard addresses are enabled, the Diamond Storage Array
will try to use its internal hard address as its address on
the loop. Under soft addressing, the Diamond Storage
Array loop address is assigned during loop initialization.
Use FcHardAddress (described below) if you enable hard
addressing. Applies to both Host Interface Cards.

Default: disabled
Set syntax: set FcHard [enabled | disabled]
Get syntax: get FcHard
Requires a SaveConfiguration command

FcHardAddress
This hexadecimal value represents the address the
Diamond Storage Array will try to use if hard addressing
is enabled. When an optional address is not present, the
current value is displayed. Each port has individual hard
address value.

Default: 0x03 for port 0, 0x04 for port 1
Set syntax: set FcHardAddress [fp |[address]]
Get syntax: get FcHardAddress [fp]
Requires a SaveConfiguration command

FcNodeName
Returns the Fibre Channel node name stored in NVRAM
for this Fibre Channel port: the same as the World Wide
Name for port 0.

Get syntax: get FcNodeName
