Hi, Now that I have my hands on a server that can boot iSCSI, I started to look into it. After figuring out what magic is needed in the dhcpd.conf (just add option root-path "iscsi:target-ip::::target-name") I can boot FreeBSD to the point that it can't find a root device, and assuming that some more magic can be applied (ala NFS), I'm just wondering aloud, if it's realy worth the efford. For a PXE based diskless solution, you need 1 - a working dhcpd 2 - a working tftpd 3 - a working NFS server with the exported root fs. appplying some minor magic, you can have only one read-only fs. For an iSCSI based diskless solution, you need 1- a working dhcpd 2- a working iscsi-initiator, unless the BIOS can be used. 3- a working target with a root fs (one for each client, unless applying 3 from the above). Hybrid solution: boot via PXE, but mount root via iSCSI So, what say you all? danny
