Advanced Communications Controller B.03.32.00 Release Notes

Patches and Fixes for this Version

Chapter 1 15

• JAGad67069

Symptoms: When an x25stat is done, the Max Frame size that is displayed is shown in

bits instead of bytes.

Defect/Fix: n2z_upper.c has been changed such that the max frame size is displayed in

bytes instead of bits.

• JAGad83768

Symptoms: Add support for ACC PCI cards on Superdome systems.

Defect/Fix: When running ACC 3.30 with Z7340A cards on a Superdome system,

zmasterd cold start fails, and the cards do not start up. zmon complains that there is

no ACC card in the slot configured. This is because an extra “0” was added to the I/O path

on Superdome systems. For example, if an N-class system had an I/O path of 16/4/1/0, on a

Superdome the same path would look like “16/4/1/0/0”. The problem is in the function

nacc1_get_interface_info() which looks at the path entries starting with the

rightmost element and working left. On a superdome system, this yielded a bus address of

4:1 and a slot address of 0 instead of 16:4 and slot address 1.

The address parsing has been changed to start with the leftmost element and then work

right for the PCI bus. This should result in consistent bus and slot addresses regardless of

the target system that supports the PCI bus.

• JAGad87791

Symptoms: ACC card description in ioscan output is insufficient.

Defect/Fix: ACC card description in “ioscan -fC acc” output needs to be more

informative. The code has been changed so that “ioscan -fC acc” output displays the

card number and the description. For instance, the “Description” field of “ioscan –fC

acc” output is as follows:

Description

==============

Z7340A PCI bridge

Z7340A 8-port serial ACC
