The FSL is activated
The fail-safe loader (FSL) is redundant or backup console that allows you to update or restore the SRM console if it is corrupted. The AlphaServer 2000, 2100 and 2100A systems utilize a ROM on either the standard I/O, motherboard or backplane module, depending on system type, to store the failsafe loader console.
As long as the fail-safe loader is intact you will get to an ash> prompt on the console and an OCP display of FAIL I/O_00 0004 when the FSL has been activated.. I have also seen FAIL I/O_00 04 and FAIL I/O_04 documented. The FSL is activated under the following circumstances: .
SRM console firmware is corrupted during upgrade (power failure, load failed)
Error in the nonvolatile nvram file
Hardware failure during power-up prevents the console firmware from loading.
A configuration error, such as an incorrect environment variable setting.
Driver error (console driver)
FSL enable switch is activated |
