This feature is new in the Solaris Express 5/04 release.
In this Solaris release, the disk drivers for SPARC and x86 platforms are merged into a single driver. This change creates one source file for the following 3 drivers:
SPARC sd for SCSI devices
x86 sd for Fibre Channel and SCSI devices
SPARC ssd for Fibre Channel devices
In previous Solaris releases, three separate drivers were needed to provide support for SCSI and Fibre Channel disk devices on the SPARC and x86 platforms. All of the disk utilities, such as the format, fmthard, and fdisk commands, have been updated to support these changes.
In addition, Solaris support for the EFI disk label is now available on x86 systems. For further information about EFI disk labels, see Multiterabyte Disk Support With EFI Disk Labels.
