missing XB80 and BB00 on a newly configured M10-4S

(Doc ID 1560945.1)

Last updated on JUNE 30, 2014

Applies to:

Fujitsu M10-4S - Version All Versions and later
Oracle Solaris on SPARC (64-bit)

Symptoms

In an XBBOX crossbar configuration using a single expansion rack with XB80, XB81, and some number of M10-4S building blocks, a XSCF dual cable is used to connect XB80 to XB81, and XSCF control cables run from each building block BB00, BB01, etcetera, to the XSCF interface units on XB80 and XB81.

In addition, a single XSCF BB control cable is run from port 16 of the XB80 XSCF IF unit to port 16 of the XB81 XSCF IF unit.  If the port 16 cable is not connected, XB81 will boot up as master and XB80 will come up as slave.  XB81, however will not detect the presence of XB80, nor will it detect the presence of BB00.  

A showlogs monitor may show the expected SCF:configuration changed messages for components of the missing BB00, but these components will fail to show up in showhardconf output.

The following error indications may appear in showlogs monitor output:

Changes

This issue is typically seen during the initial installation of multiple M10-4S building blocks.  It could also occur should the affected XSCF BB control cable becomes disconnected.
