If the disk is relabeled with an SMI label, ensure that the labeling process did not change the partitioning scheme.

In most cases, all of the disk's capacity should be in the slice that is intended for the root pool.

For information about replacing a disk in root pool, see How to Replace a Disk in the ZFS Root Pool. For more information about creating mirrored storage pools, see Mirrored Storage Pool Configuration. This pool is created with a 2-GB swap volume and a 2-GB dump volume, in a mirrored configuration of any two available devices that are large enough to create an 80-GB pool.

The steps for installing a ZFS root file system follow: If you did not create a mirrored ZFS root pool during installation, you can easily create one after the installation. You can mirror as many disks as you like, but the size of the pool that is created is determined by the smallest of the specified disks.When a system is installed or upgraded with a ZFS root file system, the size of the swap area and the dump device are dependent upon the amount of physical memory.The minimum amount of available pool space for a bootable ZFS root file system depends upon the amount of physical memory, the disk space available, and the number of boot environments (BEs) to be created.The required minimum amount of available pool space for a ZFS root file system is larger than for a UFS root file system because swap and dump devices must be separate devices in a ZFS root environment.By default, swap and dump devices are the same device in a UFS root file system.This chapter describes how to install and boot a Oracle Solaris ZFS file system.
