Guidelines for iSCSI booting using a Converged Network Adapter (CNA) or using IBFT

SUSE Linux Enterprise Server 11 Service Pack 4 (SLES 11 SP4)


There is continued support for iSCSI booting in SLES 11 SP4 using a converged network adapter card (CNA) or using iBFT, but some guidelines are helpful in setting up a proper configuration.


  • The root disk must be used for iSCSI booting using CNA or iBFT.
  • Non-boot-time volumes available via iSCSI do not need to use iBFT, but instead can be accessed using the open-iscsi initiator after the system has booted.  CNAs can be configured via open-iscsi.
  • To place other boot-time non-root volumes on iSCSI using iBFT, the root volume must also be on iSCSI volumes. SLES11 does not support having root on a local disk and swap or other system volumes on iSCSI.
