Performing an iSCSI boot
Booting from the iSCSI drive
The following sequence describes the iSCSI boot sequence.
At server boot
1. On power up, system BIOS detects the iSCSI boot option ROM.
2. iSCSI boot option ROM obtains iSCSI boot parameters from iLO/RILOE memory using the iSCSI
environment variables.
3. iSCSI boot option ROM establishes an iSCSI session with the iSCSI targets defined in the
environment variables.
4. Upon session creation, iSCSI boot option ROM establishes the iSCSI target as the local hard disk.
5. The iSCSI boot option ROM leaves the iSCSI target parameters on the adapter scratch pad for the
operating system to use.
6. The iSCSI boot option ROM loads the operating system.
7. System BIOS continues to perform I/O requests that are translated to ISCSI messages by the iSCSI
boot option ROM.
When the operating system loads
1. Network driver is loaded and network interface is configured.
2. iSCSI initiator driver is loaded and initialized.
3. iSCSI initiator driver reads target parameters from adapter scratch pad.
4. Connects to the iSCSI target.
5. iSCSI session is established and the system boots.
