When you create an inactive boot environment, you need to identify a slice where the root (/) file system is to be copied. Use the following guidelines when you select a slice for the root (/) file system. The slice must comply with the following:
Must be a slice from which the system can boot.
Must meet the recommended minimum size.
Cannot be a Veritas VxVM volume.
Can be on different physical disks or the same disk as the active root (/) file system.
If you have a sun4m system, the root (/) file system cannot be greater than 2 Gbytes.
The Choices menu displays most free slices that are available for the creation of an inactive boot environment. Some slices are free, but not available to be shown in the Choices menu, such as a Veritas VxVM volume or a Solaris Volume Manager metadevice.
