ATTO Technology Inc. Diamond Storage Array Installation and Operation Manual

6.4 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). See 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 Restart command
Get syntax: get FcConnMode

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

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

FcFairArb
Enabling this feature causes the Diamond Storage Array
to follow the arbitration fairness rules on the FC-AL.
Applies to both Fibre Channel ports

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

FcFrameLength
Sets the frame length of a command. If not specified in
the set command, current frame length is displayed.
Applies to both Fibre Channel ports

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

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 Fibre Channel ports

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

FcHard
If hard addresses are enabled, the Diamond Storage Array
tries 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 Fibre Channel ports

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

FcHardAddress
This hexadecimal value represents the address the
Diamond Storage Array tries 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]]
Requires a SaveConfiguration Restart command
Get syntax: get FcHardAddress [fp]

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

FcPortInfo
Retrieves information about the current state of each
Fibre Channel port. The status field indicates ‘disabled’
when a port has been internally disabled.

Immediate command: FcPortInfo
