FibreQuik - Fibre Channel Adapter User Guide

• Full_duplex enables higher performance in loop mode where

all connected devices support it. P2P is inherently full
duplex.

• Fibre Channel topology is normally found automatically but

may be forced to loop_only or P2P_only with this
attribute.

• Frame_size defaults to 1K
• Infinity is the length of time that the driver will wait for a

command before assuming that it has failed.

• DMA_window is used to map memory for DMA transfers on

PCI bus, 64-bit systems.

• GHz is only 1GHz for PC1000 and MC1000 cards. The

PC2000 will normally auto-detect but may be forced to
1GHz operation with this attribute.

• Sw_fc_class is normally class 3 operation. Contact customer

support if class 2 operation is required.

• Devtype_exclude will prevent the driver from configuring

specific SCSI device types (0 = disk, 1 = tape, etc.) It is
used when multiple adapters on the same fabric must not
interfere.

• Logout_delay is used to specify an upper limit on port logged

out responses before failing a command.

• BDR_mask is “all” or “none” to mask BDR ioctls. BDR

should be masked to tape driver behind a router.


cfgmgr -v >/tmp/cfg.log

Should identify the card and configure it.
If cfg.log contains the ID 77100021 and no driver is found,
then the driver is not installed.

If an MCA card is present but not configured, then check for
and remove the reset jumper on the card.

/usr/lpp/cbxfc/mbtest scsi<x> id

for each <x> adapter, should return a loop id or port name:
