Known Limitations for Sun Fire Entry-Level Midrange Systems

This section describes only those bugs with potentially significant impact. The README file lists all bugs, including those seen only internally at Sun.

prtdiag Still Shows the System Board After the Board Was DR'ed Out of the Domain (CR ID 6298989)

After a board with an UltraSPARC IV+ processor has been unconfigured out of the domain using DR, prtdiag still shows the board as being present in the domain. Issuing the psrinfo command correctly shows that the board is no longer present in that domain.

Workaround: This has been fixed in the Solaris 10 1/06 release. If you are running the Solaris 10 3/05 release, Solaris 9, or Solaris 8 on the domain, you must install a patch for your version of the Solaris OS.

These patches are available at http://sunsolve.sun.com.

Memory Page Retirement Support Should be Enabled by Default (CR ID 6411108)

To ensure that the benefit of this feature is made available to the largest number of customers, this feature is now enabled by default. However, if your system has 5.20.0 firmware installed, the installation of 5.20.1 firmware does not change the current setting of the memory page retirement feature. In that case, if the current setting of the feature is disabled, the feature will remain disabled.

To enable this feature, use the setupsc command to set the Enable Memory Page Retirement option to true. For further information, see the Sun Fire Entry-Level Midrange System Controller Command Reference Manual (part number 819-5085-10).


Note - The changed mpr-support-enable setting takes effect after the next sequence of the setkeyswitch off and setkeyswitch on commands.
