Fujitsu M10/SPARC M10 Systems Product Notes for XCP Version 2240 ･ March 2015
100
Description
In case XCP 2210 is applied to a SPARC
M10-4S, that is attached to a crossbar box
(XBBOX), if the crossbar cable is
degraded due to some problems, the
following symptom may occur while the
system is running.
- If a failure occurs in the crossbar unit
(XBU) of the crossbar box (XBBOX), it
may not be detected and the physical
partition may hang up.
Failure of crossbar cable can be
confirmed by any of the following error
logs:
FRU: /BB#n/XBU#x/CBL#y,/
BB#n/XBU#x,/XBBOX#m/XBU#x
Msg: XB-XB interface fatal bus protocol
error
Or,
FRU: /BB#n/XBU#x/CBL#y,/
BB#n/XBU#x,/XBBOX#m/XBU#x
Msg: XB-XB interface timeout error
Or,
FRU: /BB#n/XBU#x/CBL#y,/
BB#n/XBU#x,/XBBOX#m/XBU#x
Msg: XB-XB interface link-up error
In the search function for each log in the
[XSCF] - [Logs] menu on the XSCF Web,
if you click the [Search] button with both
[Start] and [End] times set to execute a
search, a message indicating an error in
the specified period may be output and it
may not be possible to execute the search.
In a system configuration with a
connected PCI expansion unit, you may
update XCP firmware or reset XSCF with
the physical partition (PPAR) powered
on. In this case, the PCI expansion unit
information is not output to the result of
executing the ioxadm(8) command or
showhardconf(8) command. Or, the PCI
expansion unit can no longer be
controlled with the ioxadm(8) command.
Workaround
If a problem of any crossbar cable has
occurred, stop all PPARs immediately
and replace the crossbar cable.
[How to restore]
1. Stop all PPARs. If any of them cannot
be stopped normally, stop it forcibly.
2. Replace the degraded crossbar cable.
3. Diagnose the hardware with the "testsb
-a" command and confirm whether
there is any failure of the XBU of
XBBOX.
4. If there is any failure in the XBU,
replace it.
Use the showlogs(8) command of the
XSCF shell.
There is no effective workaround.
[How to restore]
Execute either of the following.
- Power off the PPAR and then power it
on again.
- Use PCI hot plug (PHP) to remove the
link card from the system and reinstall
it.
