Solution 1001660.1 : Sun Enterprise [TM] E450 OBDiag errors after installing new system board

Applies to:

Sun Enterprise 450 Server - Version All Versions and later
All Platforms

Symptoms

Description:

After installing a new system board and using the NVRAM chip that came with the new system board,

the nvram values used to test system boards will probably not be set to their default values.

Thus, OBDiag may output error messages (see below) but the system will otherwise boot and operate normally.

If diag-script normal = mfg-5

diag-targets = dev+loopback

(FYI, the above nvram setting are for testing ttya, ttyb, ppp, hme and floppy. These tests require loopback

plugs installed and scratch floppy loaded.)
