Solaris 10 Installation Guide: Solaris Live Upgrade and Upgrade Planning

Changing the Name of a Boot Environment

Renaming a boot environment is often useful when you upgrade the boot environment from one Solaris release to another release. For example, following an operating system upgrade, you might rename the boot environment solaris8 to solaris10.

Use the Rename menu or lurename command to change the inactive boot environment's name.

x86 only –

Starting with the Solaris 10 1/06 release, the GRUB menu is automatically updated when you use the Rename menu or lurename command. The updated GRUB menu displays the boot environment's name in the list of boot entries. For more information about the GRUB menu, see x86: Activating a Boot Environment With the GRUB Menu.

To determine the location of the GRUB menu's menu.lst file, see x86: Locating the GRUB Menu's menu.lst File (Tasks).
