SMIT Field Definitions for Fibre Channel Adapter
The following is a summary of the Fibre Channel Attributes and values shown on the SMIT
Change / Show Characteristics of a Fibre Channel Adapter.
Fibre Channel Adapter
Identifies the logical name of the adapter. This field cannot be changed.
Description
Provides a short description of the adapter. This field cannot be changed.
Status
Indicates the current status of the adapter. Possible values are available, indicating
that the adapter is configured in the system and ready to use, and defined,
indicating that the adapter is defined to the system but not configured.
Location
The location code for an adapter consists of two pairs of digits with the format
AA–BB where AA identifies the location code of the drawer containing the adapter
card and BB identifies both the I/O bus and slot containing the card.
Driver TRANSMIT queue size [256]
This is the number of outstanding transmit packets the driver can support.
Values: 128, 256, 512, 768, and 1024.
Link Topology identifier [loop]*
Fibre Channel nodes may be connected in two topologies:
pt2pt, loop, and both (autodetect).
*
see “Link topology autosensing” page 2-11.
Xmit class identifier [3]
Three classes of service are defined for the transfer of Fibre Channel Sequences:
Class 1: ”Dedicated Connection”; a virtual ”pipe” is created between the two
N_Ports, dedicated to the transfer.
Class 2: ”Multiplexed”; each frame finds a route to the destination, delivery or
non–delivery is acknowledged.
Class 3: ”Datagram”; same as Class 2, but there is no acknowledgement of delivery
or non–delivery.
Values: 2 or 3.
Network Driver enabled [yes]
yes
for LAN operations. Otherwise
no
.
SCSI driver enabled [yes]
yes
for SCSI operations. Otherwise
no
.
512 byte Fibre Channel frame size [no]
Number of IOCB buffers to allocate [5000]
This applies to SCSI Operation. Values range from 200 to 10,000. You must
increase the value when you get an ERRLOG = out of resource
Number of data buffers to allocate [600]
This applies to Network Operation. Values range from 20 to 2,000.
Extra FCP timeout for fabrics [0]
Extra fcp timeout for fabric (time in second)
fcp Class Identifier [3]
This applies only to the fcp command.
