The Sun Fire T2000 Server requires the installation of certain specific Solaris 10 patches and configuration settings in "/etc/system" to operate correctly.

This issue can occur on the following platform:

• Sun Fire T2000 Server (running Solaris 10 HW update 2) without patches 118822-23, 119578-10, 121236-01, 121265-01, 119981-05, 120824-03, 120849-02, and 118918-09

and without these settings in the "/etc/system" file:

    set segkmem_lpsize=0x400000
    set pcie:pcie_aer_ce_mask=0x1

Notes:

1. The above patches and "/etc/system" settings only apply on those T2000 systems with Solaris 10 HW update 2.
2. The patches listed above and changes to "/etc/system" entries are mandatory for proper system operation.
3. Solaris 8 and 9 are not supported on the T2000 platform.

Potential issues that may arise without the recommended patches/configurations for the T2000 may include data loss, availability or security issues.

To avoid the described issues, the following mandatory patches must be applied:

• 118822-23 or later
• 119578-10 or later
• 121236-01 or later
• 121265-01 or later
• 119981-05 or later
• 120824-03 or later
• 120849-02 or later
• 118918-09 or later

along with the following entries that must be set in the "/etc/system" file:

    set segkmem_lpsize=0x400000
    set pcie:pcie_aer_ce_mask=0x1

Note: These mandatory patches and settings must be applied to the factory installed version of Solaris 10 on the T2000 (and verified as installed), or after any new Solaris software installation or re-installation of Solaris 10 on the T2000.

Information on required patches and settings as listed above is documented in the Sun Fire T2000 Server Product Notes which can be downloaded from http://www.sun.com/products-n-solutions/hardware/docs/Servers/coolthreads/t2000/index.html. (Please check the product notes periodically for updates to patches and workarounds).

Specifically, see the "Required Patches" and "Mandatory /etc/system File Entries" sections relating to these issues.

The T2000 is now shipping with Solaris 10 update 1, which contains the required patches for proper operation.

Note: The "/etc/system" changes required for earlier Solaris releases are not required with Solaris 10 08/07.

The "/etc/system" file for Solaris 10 11/06 will still need to be modified to add the line:

    set pcie:pcie_aer_ce_mask=0x1

For more specific information on setting these parameters for Solaris on the T2000, please see "Recommended /etc/system parameters for Sun Fire T2000 systems" at:
