Description
In a PCI expansion unit, if the power
supply unit (PSU) has a redundant
configuration and the power cable
connected to one of the power supply
units is pulled out, a PSU error may
be erroneously detected, and the PCI
expansion unit chassis Check LED
(amber) may go on. At this time,
executing the showlogs error
command outputs the "Msg: PSU
failed" log.
In a PCI expansion unit, a power
supply unit (PSU) failure is
erroneously detected if you
perform the following operations in
the condition that a power cable
connected to either of PSUs in a
redundant configuration is pulled
out.
- Power-on of a physical partition
(PPAR)
- Mount a PCI expansion unit in
PCI hot plug (PHP)
Also, Check LED (amber) of the
PCI expansion unit chassis may go
on.
You can confirm this phenomenon
with the showlogs error -v
command.
If the result of the showlogs error
-v command shows "Msg:PSU
failed", and the fifth (x08) bit from
left of the second byte of the forth
line of Diagnostic Code shows 1
(any of *8, *9, *a, *b, *c, *d, *e, *f), it
corresponds to this failure.
[Error message example]
If the left of the second byte of the
forth line of Diagnostic Code shows
"49":
XSCF> showlogs error -v

Workaround
There is no effective workaround.
[How to restore]
Use either of the following procedures.
- How to restore 1
Turn off the power to the SPARC M10
chassis connected to the PCI expansion unit.
Then disconnect both PCI expansion unit
power cables (AC OFF). Then, wait for 30
seconds to reconnect the cables (AC ON).
- How to restore 2
Perform pseudo active replacement of the
PSU in which the error has been detected
(temporarily remove the PSU and then
reinstall it). When performing pseudo
replacement of the PSU, use the ioxadm(8)
command. Note that the fieldeng privilege is
required to execute the ioxadm(8) command.

PCI expansion unit. Wait for 30 seconds, then
connect both power cables (AC ON).
