Known Issues

This section describes the known issues and workarounds at the time of this release.

IB Links on the IB Dual Port 4x DDR PCIe Fabric Expansion Modules Are Lost (CR 6777849)

When the IB-QNEM is power-cycled or hot‐plugged, all the IB links on the two IB dual port 4x DDR PCIe Fabric Expansion Modules (FEMs) plugged into Sun Blade X6270 Server Module will be lost.

Workaround: Reboot the Sun Blade X6270 Server Module after power-cycling or hot‐plugging the IB-QNEM.

show full_serial_no Command Splits the Serial Number for the IB‐QNEM (CR 6804457)

When using the ILOM IB-QNEM CLI tool, the show full_serial_no command splits the complete serial number for the IB-QNEM between the S/N and full_serial_no fields.

Using the ILOM QNEM CLI tool, the show full_serial_no command will produce output similar to the following:


-> show full_serial_no
 
NEM1
Targets:
 
Properties:
full_serial_no = 0110SJC-0904
 

The show S/N command will produce output similar to the following:


-> show S/N
 
NEM1
Targets:
 
Properties:
S/N = CA0036

Workround: To obtain the complete serial number, concatenate the values in the full_serial_no and S/N fields. For the example above the full serial number would be 0110SJC‐0904CA0036Aternatively, use the ipmitool fru print command which will produce output similar to the following:


Board Product: ASSY,SB6048 QDR NEM
Board Serial: 0110SJC-0904CA0036
Board Part Number: 541-3378-01

The full serial number would be 0110SJC-0904CA0036. Please check for the availability of a patch for this defect

Locate Button Functionality Is Not Implemented (CR 6800394)

The Locate LED will neither turn on (if off) nor turn off (if on) when the Locate button is pressed on the IB-QNEM.

Workaround: There is no workaround. Please check for the availability of a patch for this defect.
