Sun Blade X6450 Server Module Product Notes

This chapter describes software issues related to the Sun Blade X6450 server module.

Delay Before Server Can Be Powered On After Software Upgrade (6893973)

After performing a software upgrade, there is a delay of about three minutes before the server can be powered on.

Workaround

Wait three minutes or more before powering on a server after a software upgrade.

PCCheck Cannot Run Multiple Times (6875913)

If you stop and start the host more than once, PCcheck does not run after the first time, and an error message appears in dmesg:

BotReqHandler() : BOT Reset Request Called
ERROR: UsbWriteData(): Transmission timeout for Device 0 EP 2 for DataSize 0xD
Error in Sending CSW for EP2
WARNING:Wakeup for Sleep Struct(0xc71be6dc) Called after timeout
ERROR: UsbWriteData(): Transmission timeout for Device 0 EP 2 for DataSize 0x24
Error in Sending SCSI_INQUIRY 

Workaround

Retry several times until it runs.

SUSE Linux With CF Card Reports HD Errors

On systems with a CF card, SUSE 10/9 reports errors.

For example:

dmesg |grep -i fail
hda: drive_cmd: status=0x51 { DriveReady SeekComplete Error }
hda: drive_cmd: error=0x04 { DriveStatusError }

Error attaching device data
aer: probe of 0000:00:02.0:pcie01 failed with error 1
aer: probe of 0000:00:03.0:pcie01 failed with error 2

These messages can be ignored. They do not affect system performance.

Creating SSH Key During Upgrade to SW3.0 Takes Awhile

While upgrading to SW3.0, it can take about five minutes to create the SSH key. The screen displays:

SSH RSA Host Key files don't exist. Creating... 
Starting sshd 

Workaround

While this might take awhile, it should still work. No action is necessary.

Solaris x86 X-Server Fails To Start

The Solaris x86 X-Server might fail to start after it is enabled with the dtconfig -e command.

Workaround

Add the following option to the xorg.conf file:

Option “NoDDC” “True”

Windows 2003 LAN Issue

When using Receive Side Scaling (RSS) in Windows Server 2003 SP2, the interface fails, but shows no indication of failure other than a blank IP address, 0 packets received from the adapter, and a blank ARP table.

Workaround 1

Disable and re-enablethe interface to restore normal operation.

Workaround 2

Install the Installpack from the SW 2.0.3 or later ISO image. For example:

/windows/w2k3/packages/InstallPack_2_0_3.exe

For more details, please refer to the following Intel doc.

Server Modules Equipped with Additional Memory Take Longer to Run POST

A server module that is fully populated with DIMMs can take up to three additional minutes to boot, due to the time required to run POST tests on the DIMMs.

VMware ESX/ESXi 3.5 u2 Health Status is Sometimes Reported Inconsistently

VMware ESX/ESXi releases provide a health status and monitoring feature. Incompatibility between the ILOM and VMware IPMI interfaces causes ILOM IPMI sensors to be partially displayed in the VMware health status window. Sensors might also appear and disappear, and updates occur slowly.

Workaround

Use the ILOM GUI, CLI, SNMP, or IPMI interfaces to monitor server health. Also, the ILOM provides remote syslog and remote alert interfaces to enable remote monitoring.

VMware ESX 3.5 Process Uses 100% of Core

The VMware ESX 3.5 process occasionally uses 100% of a core.

For example:

# cat /proc/vmware/interrupts
Vector PCPU 0   PCPU 1   PCPU 2   PCPU 3   PCPU 4   PCPU 5   PCPU 6   PCPU 7
0x21:  7442833       0        0        0        0        0        0        0 VMK ACPI Interrupt 

Workaround

1. Edit the file /etc/vmware/esx.conf and add the line /vmkernel/mpsIntRouting = "TRUE".

2. Reboot the system.

Arrow Keys Do Not Work When Using RKVM on SunRay

The arrow keys do not work when using an RKVM on a SunRay.

Workaround

Use alternative keystrokes, or remap the arrow keystrokes in the SunRay X session.

Keyboard Alt Key Appears Stuck in RKVM on RHEL4 and ESX 3.5 u2

During RKVM sessions with RHEL4 and ESX 3.5 u2, the Alt key appears stuck.

Workaround

  From the javaRconsole menu:

• Select Keyboard ->Left Alt Key.
• Deselect Keyboard ->Left Alt Key.

When Installing Windows OS Use the Drivers on the Tools and Drivers DVD Exclusively

If you are installing the Windows OS with the QLogic Fibre Channel Adapter, do not use the drivers on the Windows DVD.

When the installation wizard informs you "The driver you provided seems to be newer than the Windows default driver.", select "S" to use the driver on the DVD.

With Solaris 10 8/07, Oracle Floating Point Processes can Generate Unexpected SIGFPE Signals and Exit

These are not actual floating point errors and the unexpected exit can cause data corruption.

Solution

Two patches to the Solaris OS must be applied, in sequence: patch 125370-06, followed by 127112-10.

Pc-Check Test User Pattern Test Does Not Finish

The Pc-Check test User Pattern Test does not finish.

Workaround

There is no functional impact. If this problem is seen, simply exit the test.

RHEL 5.0 Panics During Boot With More Than 64 GB Memory

The message Panic on CPU0: Not enough RAM for domain 0 allocation is displayed. This panic is caused by certain allocations taking up too much memory in the lower memory of the kernel.

Solution

To fix the problem, update the OS with Red Hat Security Advisory RHSA-2007:0099, or later, which contains a fix for this issue.

https://rhn.redhat.com/errata/RHSA-2007-0099.html

Workaround

If you are unable to update the kernel successfully, there is a workaround available. Boot with the system with the kernel parameters dom0_mem=512M mem=64G. For example, in /boot/grub/grub.conf file, enter the parameter like this:

title Red Hat Enterprise Linux Server (2.6.18-8.el5xen)
root (hd0,0)
kernel /xen.gz-2.6.18-4.el5 dom0_mem=512M mem=64G
module /vmlinuz-2.6.18-4.el5xen ro root=LABEL=/
module /initrd-2.6.18-4.el5xen.img 

Flood of Interrupts with VMware ESX 3.5

When using ESX 3.5 there is an interrupt flooding at vector 0x21 which results in more than 90% usage of one core.

This issue has been fixed with BIOS version 3A08 of SW release 1.0.1.

Solaris OS Will not Install on 1 TByte RAID

The Solaris OS cannot be installed on a RAID array larger than one terabyte.

The Solaris installer OS doesn’t support it.

Workaround

There is no workaround for this issue.

Reduced Network Performance With Solaris 10 5/08

Servers running the Solaris 10 5/08 OS may experience reduced network performance.

Workaround

Add patch 137112-06.

x86: i86_mwait Function Does Not Function as Designed (6736444)

Systems with the Intel® Xeon® Processor MP7400 series running the Solaris 10 10/08 OS might experience slightly reduced performance or increased power consumption under light utilization due to an issue where the CPUs might not idle fully.

No error message is displayed.

Workaround

Add the following line to /etc/system file:

set idle_cpu_prefer_mwait=0

Reboot the system.

Ctrl+Alt+Delete Does not Work for SLES10 SP1

When using RKVM, the Ctrl+Alt+Delete hot key does not function for the SLES10 SP1 OS.

Workaround

Use SP to reset your system, or reboot it using OS commands.
