<SUNBUG: 6338258>, <SUNBUG: 6338338>, <SUNBUG: 6315997>, <SUNBUG: 6274126>, <SUNBUG: 6332746>

Date of Resolved Release

Impact

The Sun Fire T2000 Server running Solaris 10 3/05 HW2 requires the installation of certain specific Solaris 10 patches and configuration settings in "/etc/system" to operate correctly.

Contributing Factors

This issue can occur on the following platform:

Sun Fire T2000 Server (running Solaris 10 3/05 HW2) 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:

This issue only applies to T2000 systems installed with Solaris 10 3/05 HW2.
The patches listed above and changes to "/etc/system" entries are mandatory for proper system operation.
Solaris 8 and 9 are not supported on the T2000 platform.

Symptoms

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

Workaround

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.

Resolution

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:

Internal Comments

This Sun Alert is meant to point out that the patches described
were not included in the pre-install Solaris image.

These patches and workarounds are documented in the
Sun Fire T2000 product notes. This SunAlert is intended to highlight their importance and increase
the probability that customers will apply them after any re-install.
The T2000 (RoHS compliant version) is now shipping with
Solaris 10 update 1, which contains the required patches for proper operation. Please see the T2000
Server Product Notes for details on how to identify which version you have, and for the latest information
on required patches and "/etc/system" edits.
The remaining item for the newer systems with S10U1 is to add:
set pcie:pcie_aer_ce_mask=0x1

Additional Note:
The need to set pcie:pcie_aer_ce_mask=0x1 is required unless patch 120011-14 is installed.
