EFI Disk Label Overview
Extensible Firmware Interface (EFI) is an Intel standard used as a replacement for
the PC BIOS. It is responsible for the power-on self-test (POST) process, booting the
operating system, and providing an interface between the operating system and the
physical hardware. EFIs provides the following capabilities:
■
System-independent device drivers.
■
Delegation of networking and memory management issues to the firmware
instead of the OS.
■
EFI selection and loading of the operating system, which removes the need for a
boot loader.
Solaris 10 provides support for EFI Labels for disks that are larger than 1 terabyte on
systems that run a 64-bit Solaris kernel. The Extensible Firmware Interface GUID
Partition Table (EFI GPT) disk label provides support for physical disks and virtual
disk volumes.
You can download the EFI specification at:
http://www.intel.com/technology/efi/main_specification.htm
You can use the
format -e
command to apply an EFI label to a disk if the system
is running the appropriate Solaris release. However, you should review the
important information in Restrictions of the EFI Disk Label before attempting to
apply an EFI label.
For additional information about EFI disk labels, managing disks with EFI labels,
EFI disk label restrictions, and troubleshooting problems with EFI disk labels, refer
