Description
If a crossbar box has failed in the system
that satisfies all the following conditions,
a crossbar box may be degraded and the
operation may not be continued.
- Two or more crossbar boxes are
configured.
- Multiple PPARs are configured.
- Each physical partition (PPAR) is
configured with multiple CPU memory
units (CMUU/CMUL).
If you forcefully turn off the power of the
physical partition using the poweroff -f
command immediately after you
powered on the physical partition, you
may not be able to power on/off the
physical partition after that.
In SPARC M10-4/M10-4S, if the firmware
version is XCP 2031 or XCP 2032, the
initial value of the following OpenBoot
PROM environment variable differs from
the default.
Even if the setting is changed by using
the setpparparam(8) command of the
XSCF shell or the setenv command from
the OpenBoot PROM prompt, it will
return to the original value.
auto-boot? false
diag-switch? true
fcode-debug? true
local-mac-address? false
If the PCI device in the I/O domain is
deleted (ldm rm-io) or a PCI device is
added (ldm add-io), hypervisor abort
may occur when the I/O domain starts.
If the XSCF mounted in the crossbar box
panics, it may be impossible to perform
communication between the master
XSCF and non-master XSCF.
Workaround
There is no effective workaround.
[How to restore]
Execute the poweron -p command to
power on the PPAR again whose power
has been turned off due to an error in the
crossbar box.
After powering on a PPAR, do not
execute the poweroff -f command until
the ok prompt is displayed.
[How to restore]
If you fail to forcefully turn off the power
of a PPAR, power off the input power
supply and then turn on the power again
(AC OFF/ON).
There is no effective workaround.
Make a firmware update to XCP 2041 or
a later version, and then set the value of
the OpenBoot PROM environment
variable again.
To delete the PCI device in the I/O
domain, delete all devices under the
same route complex as that of the PCI
device to be deleted (which have the
same xxxx of /pci@xxxx) and then add
the necessary devices again.
Alternatively, do not assign multiple
devices under the same route complex to
a single I/O domain.
There is no effective workaround.
[How to restore]
If the event occurs, wait for 15 minutes or
longer, and then use rebootxscf -s to reset
the master XSCF.
