ISCSI Bootstrapping Draft Prasenjit Sarkar IBM
Requirements • Provide guideline for iSCSI boot clients to contact iSCSI boot server • iSCSI boot clients needs: • IP address • iSCSI boot server Service Delivery Port Name, default LUN = 0 • Overrides possible for port and LUN • iSCSI initiator software • On start, iSCSI boot client may have nothing • No subset of iSCSI intiator software to be defined • Unattended bootstrapping with overrides
Steps • Client Software Stage: • use PXE or related BOOTP/TFTP protocol to get iSCSI intiator software • DHCP Stage • Use DHCP to configure client IP address • Use new DHCP option to configure iSCSI boot server Service Delivery Port Name • Discovery Server Stage • Use to-be-defined iSCSI discovery service to get iSCSI boot server • ‘bootable’ attribute on iSCSI targets desirable • Boot stage
