1. Summary
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 dif-
ferent ways on x86 and sparc (iBFT/OBP respectively).
2. Decision & Precedence Information
The project is approved as specified in references [1], [2],
[3], [4], and [5].
The project may be delivered in a minor release of Solaris.
The project depends on the following other projects and may
not be installed on SPARC platforms before this is approved.
FWARC/2008/466
3. Interfaces
The project exports the following interfaces.

4. Opinion
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.
The installer team relies on this project to improve the NEW
installer to configure iSCSI disk during installation.
The dump solution for diskless clients will also work with
iSCSI boot.
This supercedes a previous case, PSARC/2007/450, which had
no deliverables, and addresses all issues raised during that
case's discussion.
