Two-Terabyte Disk Support for Installing and Booting the Solaris OS

Starting with the Solaris 10 10/09 release, you can install and boot the Solaris OS from a disk that is up to 2 Tbytes in size. In previous Solaris releases, you could not install and boot the Solaris OS from a disk that was greater than 1 Tbyte in size.

In this Solaris release, you can use the VTOC label on a disk of any size. However, the addressable space by the VTOC is limited to 2 Tbytes. This feature enables disks that are larger than 2 Tbytes to also be used as boot drive. However, the usable space from label is limited to 2 Tbytes.

This feature is available only on systems that run a 64-bit kernel. A minimum of 1 Gbyte of memory is required for x86–based systems.

For more information about the Solaris disk drivers and disk utilities that have been updated to support boot on disks greater than 1 Tbyte, see System Administration Guide: Devices and File Systems.
