A.10 iSCSI Boot
Mellanox FlexBoot enables an iSCSI-boot of an OS located on a remote iSCSI Target. It has a
built-in iSCSI Initiator which can connect to the remote iSCSI Target and load from it the kernel
and
initrd (Linux). There are two instances of connection to the remote iSCSI Target: the first
is for getting the kernel and
initrd via FlexBoot, and the second is for loading other parts of the
OS via
initrd.
If you choose to continue loading the OS (after boot) through the HCA device driver, please ver-
ify that the initrd image includes the HCA driver as described in Section A.8.
