Description
In case of a SPARC M10-4S that is
attached to cross-bar box, if XSCF failure
occurs on a portion of chassis when the
physical partition (PPAR) is in the
powered on state, the follow symptom
may occur:
- Symptom 1
When the poweroff(8) command is
executed, the power on the PPAR is
turned off, but the command prompt
does not respond for about 20 minutes.
- Symptom 2
When the PPAR is powered on, the
"XB-XB interface fatal error" error is
produced, the power on process is
repeated and it does not end properly.
On a physical partition (PPAR) that is
composed of several SPARC M10-4S
(system board) , after a system board has
been degraded due to failure, if the
setpciboxdio(8) command is executed to
disable/enable the direct I/O feature of
the PCI card mounted on the PCI
expansion unit which is attached to the
degraded chassis, without powering off
the PPAR first, the following message is
output and the command fails:
"This operation cannot be done because
the PPAR including a PSB of the target
BB is powered on"
This symptom occurs when the state of
system board is like the following, which
can be derive from either the
showhardconf(8) or the showboards(8)
command.
[Example] When PSB#01-0 (BB#01) has
been degraded.
XSCF> showhardconf
...
* BB#01 Status:Deconfigured;
...
XSCF> showboards -a

Workaround
If XSCF failure has occurred, replace the
CPU memory unit lower (CMUL) or the
XSCF unit.
[How to restore]
- Case of symptom 1
After about 20 minutes, the poweroff(8)
command ends properly and the
prompt comes back.
- Case of symptom 2
Forcibly power off the PPAR using the
"poweroff -f" command.
Change the configuration of the direct
I/O feature with the setpciboxdio(8)
command only after removing the
degraded system board from the physical
partition with the deleteboard(8)
command.
[Example]
XSCF> deleteboard -c unassign 01-0
After changing the configuration of the
direct I/O feature, assign the system
board to the PPAR with the addboard(8)
command and then mount the system
board onto the PPAR, following the
maintenance procedure.
[Example]
XSCF> addboard -c assign -p 0 01-0
Meanwhile, from XCP 2210 onwards, this
problem can be solved by performing
maintenance on the degraded chassis by
the replacefru(8) command. In such a
case, the above procedure is unnecessary.
