Summary
.LP
iSCSI boot project enables Solaris to boot-off iSCSI disk both on x86 and
sparc. It modifies Solaris' Kernel stage to load the information of iSCSI
boot disk, enumerate it and finally mount the rootfs from there. The
information of iSCSI boot disk is passed to the Solaris kernel in very
different ways on x86 and sparc (iBFT/OBP respectively).

Decision & Precedence Information
.LP
The project is approved as specified in references [1], [2], [3], [4], and
[5].
.LP
The project may be delivered in a minor release of Solaris.
.LP
The project depends on the following other projects and may not be installed
on SPARC platforms before this is approved.

OBP properties for iSCSI Boot
.TE
.NH
Opinion
.LP
The vendor firmware must provide iSCSI boot support, and must provide the
CHAP implementation. For SPARC, the OBP project will address this in FWARC/
2008/466.
.br
The installer team relies on this project to improve the NEW installer to
configure iSCSI disk during installation.
.br
The dump solution for diskless clients will also work with iSCSI boot.
.br
This supercedes a previous case, PSARC/2007/450, which had no deliverables,
and addresses all issues raised during that case's discussion.
