For iSCI/SAN, I did find this: https://wiki.debian.org/SAN/iSCSI

The external article it links to is dead, but can be found at
https://web.archive.org/web/20160419061242/http://linux.netapp.com/docs/debian/iscsi-sanboot-configuration-guide

But this is for installation.

For booting from iSCIS/SAN, it seems they don't support it:

"
Booting Debian with iSCSI root disk

There is no way to do this with the standard Debian initrd. The
init4boot[0] project supplies the needed infrastructure (especially an
adapted initrd). Standard PXE / tftp boot with iSCSI root and XEN guest
systems with iSCSI root are supported.

Best I can do, but I will say that it's a good idea to mount a regular
install ISO from a distribution and poke around their syslinux/grub/etc.
configurations on the image as that gives you a good idea of some kernel
commandline hints you'd need.
