Solaris/SPARC: Remove a Devalias with nvunalias

Last Updated on

BootPROM device aliases simplify life when booting a SPARC-based Solaris system. If changes to the system invalidate a device alias, leaving it may complicate matters during panic times when things need to be clear. This tech-recipe describes deleting a device alias with nvunalias.

To delete the device alias oldboot, use the following command from the BootPROM (ok prompt):

nvunalias oldboot

The only reference needed by nvunalias is the alias, not the device path.
