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

Solaris Express Community Edition, build 99: 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 the SXCE build 99 release, you can install and boot the Solaris OS from a disk that is up to 2 Tbytes in size. In previous releases, you also had to use an EFI label for a disk that is larger than 1 Tbytes. In this release, you can use the VTOC label on any size disk, but the addressable space by the VTOC is limited to 2 Tbytes.

The Solaris disk drivers and disk utilities have been updated to provide the following support:

Keep in mind that you cannot move a disk over 1 Tbyte with a legacy MBR or a legacy VTOC to a previous Solaris release. EFI labeled disks continue to work as in previous Solaris releases.

For more information about the EFI label changes in this release, see EFI Disk Label.
