Bug Id
<SUNBUG: 6474536>

Date of Resolved Release
12-DEC-2006

Impact

With OBP parameter settings "diag-switch?=true" and "diag-level=max" set, upgrading the OBP (Standalone Flash Update) on Sun Ultra 25 or Sun Ultra 45 systems may cause POST to hang or OBP to generate a "RED STATE Exception" error. The system may also become unbootable.

Contributing Factors

This issue can occur on the following platforms:

Sun Ultra 25 with patch 121687-01 and without patch 121687-02
Sun Ultra 45 with patch 121686-01 and without patch 121686-02

Note: The issue is not with the OBP binaries within these patches. The issue is caused by a bug in the Standalone Flash update "Makefile," which builds the combined Standalone Flash-Update image integrating the OBP, POST and obdiag binaries. POST is not able to run because it is not properly configured in the PROM space.

Symptoms

Should the described issue occur, POST will hang or the system may generate a RED STATE Exception error. The system may become unbootable.

Workaround

Prior to running the standalone flash update utility, set the OBP parameters "diag-switch?=false" and "diag-trigger=none". After running the standalone flash update utility, POST will not run and OBP will boot normally.

Resolution

This issue is addressed on the following platforms:

Sun Ultra 25 with patch 121687-02 or later
Sun Ultra 45 with patch 121686-02 or later
