Copying File Systems

Creating a new boot environment entails copying critical file systems to another slice. The disk might need to be prepared before you create the new boot environment. Check the disk to make sure it is formatted properly:

The process of creating a new boot environment begins by identifying an unused slice where the critical file systems can be copied. If a slice is not available or a slice does not meet the minimum requirements, you need to format a new slice. For the procedure on formatting a slice from menus, see “To Create a Boot Environment (Character Interface)” Step 6.

After the slice is defined, you can reconfigure the file systems on the new boot environment before the file systems are copied into the directories. You reconfigure file systems by splitting and merging them, which provides a simple way of editing the vfstab to connect and disconnect file system directories. You can merge file systems into their parent directories by specifying the same mount point, or you can split file systems from their parent directories by specifying different mount points.

For procedures on splitting and merging file systems, see the following procedures:

After file systems are configured on the inactive boot environment, you begin the automatic copy. Critical file systems are copied to the designated directories. Shareable file systems are not copied, but are shared. The exception is that you can designate some file systems to be copied. When the file systems are copied from the active to the inactive boot environment, the files are directed to the newly defined directories. The active boot environment is not changed in any way. For procedures on creating a new boot environment, see Creating a New Boot Environment.

The following figures illustrate various ways of creating new boot environments.
