This chapter supports the newest release and the previous release of firmware qualified for use on IBM FC Bridges with the DYNIX/ptx V4.6.x operating systems.
New Release: V1.5.5, Section 7.1
Previous Release: V1.5.4, Section 7.2
The February 2001 release of FC Bridge firmware for DYNIX/ptx V4.6.1 is named V1.5.5.
This section contains the following subsections:
V1.5.5 of the FC Bridge firmware is compatible with:
DYNIX/ptx V4.6.1 and other members of system-software release sets as listed in Table 1-1, "'Best Recipe' FC-Firmware Release Sets for DYNIX/ptx V4.6.x System," in Chapter 1.
Switched and two-node arbitrated-loop fabrics
ATTENTION By default, the FC Bridge firmware is configured to support a switched fabric. For information on how to reconfigure it for other fabric types as needed, see the Service Note "Setting the Topology on the FC Bridge via the RS-232 Port," ( http://crg8.sequent.com/cgi-bin/doc?technote=hw/fibre/fibrech/30 ).
All OFC and non-OFC multimode fiber-optic FC components
EMC Symmetrix Storage Subsystems running at least V5265.44.28 firmware.
CLARiiON DASS Storage Subsystems running at least LIC firmware V9.55.01.
V1.5.5 is a maintenance release and includes the same functionality as Version V1.5.4, with the addition of improved compatibility in interactions with IBM 2109 and SilkWorm 2000 FC Switches.
The following problems were fixed in V1.5.5:
(251104) FC Bridge firmware incorrectly reported to the switch name server that it supported all FC classes of service, when it is only a class 3 device.
(251946) Occasionally, during the initialization phase between an IBM 2109 or a SilkWorm 2000 FC Switch and an FC Bridge, the Bridge would fail to establish the low-level hardware FC link with the Switch and stop trying.
(251947) During the initialization process (FLOGI) between an IBM 2109 or a SilkWorm 2000 FC Switch and an FC Bridge, an unknown frame type received by the FC Bridge caused it to crash.
(254608) Issuing I/Os of 32 kB or larger to a DLT tape device would cause a parity error and panic the Bridge.
At this time, no Critical or Serious problems have been reported specifically against the V1.5.5 FC Bridge firmware. See "FC I/O Subsystem-Level Problem Reports," Chapter 2 for possible I/O subsystem-level problems involving FC Bridges.
The FC Bridge V1.5.5 software is installed on the system when the cfwdl-Compatible Firmware Bundle is installed on your host. The cfwdl-Compatible Firmware Bundle contains firmware that is downloaded only with the common firmware downloader, cfwdl. For details on the other software installed by this bundle, refer to the cfwdl-Compatible Firmware Bundle V1.3.1 Release Notes.
The name of the firmware file for FC Bridge V1.5.5 is fcbr_155.sqfw.
Download firmware in any or all FC Bridges by using the procedures provided in the "Download Firmware with cfwdl" chapter of the DYNIX/ptx V4.6.1 and Layered Products Software Installation Release Notes.
The September 2000 release of FC Bridge firmware for DYNIX/ptx V4.6.0 is named V1.5.4.
This section contains the following subsections:
V1.5.4 of the FC Bridge firmware is compatible with:
DYNIX/ptx V4.6.0 and other members of system-software release sets as listed in Table 1-1, "'Best Recipe' FC-Firmware Release Sets for DYNIX/ptx V4.6.x System," in Chapter 1.
Switched and two-node arbitrated-loop fabrics
ATTENTION The firmware is configured to support a switched fabric by default. For information on how to reconfigure it for other fabric types as needed, see the Service Note "Setting the Topology on the FC Bridge via the RS-232 Port," ( http://crg8.sequent.com/cgi-bin/doc?technote=hw/fibre/fibrech/30 ).
All OFC and non-OFC multimode fiber-optic FC components
EMC Symmetrix Storage Subsystems running at least V5265.44.28 firmware.
CLARiiON DASS Storage Subsystems running at least LIC firmware V9.55.01.
V1.5.4 is a maintenance release and includes the same functionality as Version V1.5.3, with the addition of improved compatibility in interactions with the IBM 2109 and SilkWorm 2000-family switches.
The following problems were fixed in V1.5.4:
(251104) FC Bridge firmware incorrectly reported to the switch name server that it supported all FC classes of service, when it is only a class 3 device.
(251946) Occasionally, during the initialization phase between an IBM 2109 or a SilkWorm 2000-family FC Switch and an FC Bridge, the Bridge would fail to establish the low-level hardware FC link with the switch and stop trying.
(251947) During the initialization process (FLOGI) between an IBM 2109 or a SilkWorm 2000-family switch and an FC Bridge, an unknown frame type received by the FC Bridge caused it to crash.
At this time, no problems have been reported specifically against the V1.5.4 FC Bridge firmware. See "FC I/O Subsystem-Level Problem Reports," Chapter 2 for possible I/O subsystem-level problems involving FC Bridges.
The FC Bridge V1.5.4 software is installed on the system when the cfwdl-Compatible Firmware Bundle is installed on your host. The cfwdl-Compatible Firmware Bundle contains firmware that is downloaded only with the common firmware downloader, cfwdl. (DYNIX/ptx V4.4.x used fcdl to download FC Host Adapter firmware.) For details on the other software installed by this bundle, refer to the cfwdl-Compatible Firmware Bundle V1.1.x Release Notes.
The name of the firmware file for FC Bridge V1.5.4 is fcbr_154.sqfw.
Procedures for using the cfwdl utility to download firmware in any or all FC Bridges are provided in the "Download Firmware with cfwdl"chapter of the DYNIX/ptx V4.6.0 and Layered Products Software Installation Release Notes.
