Solaristrademark Predictive Self-Healing (PSH) feature

The Solaris PSH implementation is not fully implemented in this release of the product. If a PSH message with a message ID of FMD-8000-OW occurs, refer to the instructions at: http://www.sun.com/msg/FMD-8000-0W.

Sun Explorer utility

This server is supported by the Suntrademark Explorer 5.2 data collection utility, but is not supported by earlier releases of the utility. Installing Suntrademark Cluster or Sun Net Connect software from the pre-installed Java ES package will automatically install an earlier version of the utility on your system. After installing any of the Java ES software, determine whether an earlier version of the Sun Explorer product has been installed on your system by typing the following:

# pkginfo -l SUNWexplo

If an earlier version exists, uninstall it and install version 5.2, or later. To download Sun Explorer 5.2, go to:

For more information about these CRs, visit the SunSolve web site.

TABLE 2-3 Specific Issues for the Sun Fire T2000 Server with Part Number 501-7501





The SunVTS USB keyboard test (usbtest) reports that a keyboard is present when there is no keyboard attached to the server.

Do not run the usbtest.


When accessing the host through the ALOM CMT console command, you might experience slow console response.

For optimum responsiveness, access the host through the host network interfaces as soon as the host has completed booting the OS.


Executing the ALOM CMT break and go commands might cause the system to hang.

If the console hangs, reset the system.


Recycling AC power results in the following erroneous message:
Preceding SC reset due to watchdog

Disregard this message.


Typing unrecognized commands or words at the ok prompt causes the system to return the following erroneous error:

ERROR: Last Trap

and might hang the server.

Disregard this erroneous error message. If the server hangs, reset the server from the system console.


Whenever the system resets, including after a POST reset, you might see the following message: Host system has shut down

Disregard this message. The system will be reset and display the OBP ok prompt as expected.


PCI-X slots cannot be disabled individually.

If you need to disable PCIX0 or PCIX1 you must disable both slots.


The console history boot and run logs are the same.

At this time, no workaround is available for this issue.


The OBP and Solaris banners display a product name of Sun Fire T200.

The correct product name should read Sun Fire T2000. This issue has no impact on the system.


After a failed DIMM was cleared from the asr database, ALOM CMT might not properly reboot and returns the following error message:
No valid MEMORY configuration

Wait 10 seconds after executing the clearasrdb command before executing the resetsc command. Refer to the Sun Fire T2000 Server Service Manual for information about clearing DIMM-related faults.


Sun Net Connect 3.2.2 software does not monitor environmental alarms on the Sun Fire T2000 server.

To receive notification that an environmental error has occurred, use the ALOM CMT mgt_mailalert feature to have ALOM CMT send an email when an event occurs.

To check whether or not the environmental status of the server is ok, log on to ALOM CMT and run the showfaults command.

To view a history of any events the server encountered, log on to ALOM CMT and run the showlogs command.


The system might hang after a panic when the sync command is used.

If the server hangs, reset the server from the system console.


If a CPU or memory fault occurs while the server is running a trap handler, the system might panic with a bad trap instead of providing a CPU or memory fault message. In such cases, memory scrubbing is not performed.

Reset the server, and check the server for possible faults using the showfaults command.


When a Solaris PSH error is detected and reported, the following erroneous message (in addition to the correct message) might be reported:

msg = warning: bad proto frame implies corrupt/lost msg(s)

Disregard the erroneous message.


The server does not answer incoming calls on the ALOM CMT serial management port.

Do not connect a modem to the ALOM CMT serial port.



SunVTS memory tests, in rare cases, might log a warning message similar to the following when the ECC Error Monitor (errmon) option is enabled:

WARNING: software error encountered while processing /ar/fm/fmd/errlog Additional-Information: end-offile reached

Do not enable the errmon option. The errmon option is disabled by default.


The system might generate erroneous fault messages with the following message IDs:




Make sure that the following line is in the /etc/system file:

set pcie:pcie_aer_ce_mask=0x1

See Mandatory /etc/system File Entries.


The raidctl command, which provides a status of the hardware RAID volumes, might report an incorrect disk target ID for a disk that is removed from the chassis and the system is rebooted.

The raidctl command will report the correct target ID when the disk is reinstalled.


The ALOM showlogs -p p command displays a lot of data and could slow down the ALOM CLI.

To display the persistent log, use the following command instead:

showlogs -e x

where x specifies the number of lines (most recent log entries) to be displayed.


When SunVTS testing is stopped while the dtlbtest is running, the test might fail with the following error:

No CPUs to test

Upgrade to SunVTS 6.1 PS1. This release of SunVTS is available from:


At the ok prompt, you can only enter text up to 114 characters.

Do not attempt to enter more than 114 characters at the ok prompt.


System fault messages and ALOM CMT alerts continue to be generated at boot time after the fault has been repaired.

This issue is fixed when the mandatory patch, 119578-22 or greater, is installed. See Required Patches.

If this patch is not installed, you can clear system fault messages by performing the procedure described in the Sun Fire T2000 Server Service Manual.


When a grounding wire is connected to the grounding pin on the rear of the chassis, it is not possible to change rear blower without removing the ground connection.

If you need to replace the rear blower unit, and there is a grounding wire connected, remove the grounding wire to access the blower unit.


The system cannot boot if a Sun type-7 keyboard is plugged into one of the front USB ports.

Do not plug a type-7 keyboard into any of the front USB ports. Instead, use a different kind of keyboard, or use the rear USB ports.


USB support is only provided when you install the Entire Distribution +OEM Solaris cluster.

If you plan to use the onboard USB interfaces, make sure you choose the Entire Distribution +OEM (SUNWCXall) cluster when you install the Solaris OS.


The probe-scsi command does not probe devices connected to onboard disk controller.

Instead, use the probe-scsi-all command.


The DVD drive does not perform write operations using a speed of x24.

When using the cdrw command to write to the DVD drive, do not use the following command:

cdrw -p24

Instead, use one of the following speeds:

  • cdrw -p16
  • cdrw -p10


Intermittently, upon a system host power-on or reset, the system powers down with the following message:

HV Abort: JBI Error (22) - PowerDown

Disregard this message. If the server hangs, reset the server from the system console.



The server fails to boot from a Linux tftp boot server on the network.

Use a Solaris OS tftp boot server.


The ALOM disablecomponent command does not disable the Ethernet ports.

Do not use the disablecomponent command to disable the Ethernet ports.


The following PSH fault messages might be displayed while booting from disk, after booting from the network:
SUNW-MSG-ID: SUN4-8000-5A, TYPE: Defect, VER: 1, SEVERITY: Critical

See Fault Messages Displayed While Booting From Disk, After Booting From the Network (CR 6424812).


X-option and replacement hard drives might not have an electronic disk label.

If you plan to replace or add a hard drive to your server, the drive might not have an electronic disk label and you must run the Format utility to label the drive. Instructions for labeling the drive are provided in a document titled Labeling Unlabeled Hard Drives (part number 819-3805), which is posted with the Sun Fire T2000 server documentation at: http://www.sun.com/documentation
