Problems Resolved in Version 1130 of the PCI Expansion Unit Firmware


Problems Resolved in Version 1130 of the PCI Expansion Unit Firmware
The following table lists the problems resolved in version 1130 of the PCI expansion unit firmware.
Table 7-10  Problems Resolved in Version 1130 of the PCI Expansion Unit Firmware
RTI No. RTIF2-131120-001
Model SPARC M10-1, SPARC M10-4, SPARC M10-4S
Description If an external factor causes an instantaneous voltage drop or the like, an error in the power supply unit (PSU) of the PCI expansion unit is erroneously detected, and the error log of "Msg: PSU failed" may be registered. Moreover, if the erroneous detection of this PSU error occurs simultaneously in two PSUs of the PCI expansion unit, the physical partition (PPAR) is shut down.
You can use the showlogs error -v command to check whether this problem is due to an instantaneous voltage drop caused by an external factor. Suppose that the execution result for this command is "Msg: PSU failed" and that the first, second, and third bytes on the fourth line of the Diagnostic Code have the following values. The problem may be due to, for example, an instantaneous voltage drop caused by an external factor.
First byte; "00"
Second byte; The sixth (x04) bit from the left is 0 (any of *0, *1 *2, *3, *8, *9, *a, or *b).
Third byte: The third (x20) bit from the left is 1 (any of 2*, 3*, 6*, 7*, a*, b*, e*, or f*).
"*" for the second and third bytes indicates any value.
<Example> The first to third bytes on the fourth line of the Diagnostic Code are "000120"

Workaround There is no effective workaround.
If the value of the first to third bytes on the fourth line of Diagnostic Code does not match the value in the [Description] column, assume that a PSU failure occurred.
[How to restore]
-- If this event occurs in a single PSU
- If the error log "Msg: PSU RECOVERY" is registered, the system has already been restored from an instantaneous voltage drop. The system can be operated continuously.
- If the error log "Msg: PSU RECOVERY" is not registered, a PSU failure has occurred. Replace the PSU.

-- If this event occurs in two PSUs
The PPAR is shut down. Reactivate the PPAR. If the PCI expansion unit cannot be powered on, it indicates that a PSU has failed. Replace the PSU.
