FibrChanl-00 (HP PCI Tachyon TL/TS/XL2 Fibre Channel Driver)
The HP PCI Tachyon TL/TS/XL2 Fibre Channel (td) driver manages the A6795A and
A5158A PCI single-port host bus adapters (HBAs) that utilize the Tachyon TL/TS and
XL2 chips respectively.
Summary of Change
The B.11.23.0706 version of FibrChanl-00 driver includes the following changes:
•The td driver has been changed to report the event of a link going down when an FC
cable is disconnected.
• Changes have been made in the td driver to make sure that the diagnostic event #23
(Fibre Channel driver has gone into non-participating mode) with severity SERIOUS
does not get reported erroneously by the EMS framework.
• Allows non-root user processes to load the SNIA HBA API library.
• Support has been added in SNIA API to display the Serial Number for an FC card.
• The example program /opt/snia/demos/snia_demo.c has been modified to
correctly display the port information for dual port FC HBAs.
• Changes have been made in the td driver to make sure that the Fabric World Wide
Name (WWN) for an HBA does not contain a stale value, when the topology of the
HBA is changed from fabric to private loop.
• Support for PA-RISC build has been added in the makefile
/opt/snia/demos/makefile.demo.
• Formerly, Base-VXVM logs error in /etc/rc.log due to presence of extraneous
characters in the configuration file /etc/hba.conf. This has been corrected in this
version of the td driver.
Impact
• The event “Fibre Channel Driver received Link Dead Notification” will be logged by
the td driver when an FC cable is disconnected.
• In earlier versions of the td driver, the diagnostic event #23 (Fibre Channel driver
has gone into non-participating mode) with severity SERIOUS would get reported by
the EMS framework even when a Tachlite XL2 card is functional in fabric topology.
This is corrected in the current version of the td driver.
• An application that attempts to load the SNIA HBA API library as a non-root user
will be able to load successfully.
• Support is added in SNIA API to display the Serial Number for a FC card, obtained
from the Vital Product Data (VPD) of the card.
