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

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]

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

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
