You can use the text installer to install the Oracle Solaris operating system onto an iSCSI target if the iSCSI target can act as a boot disk and if the system has the necessary support for iSCSI booting. If your system supports autodiscovery of iSCSI disks, the installer provides that option. Alternately, you can manually enter values to specify the iSCSI target in the installation screens. To use iSCSI, the network interface for the system must be configured with a static IP address before starting the installation process. Note the following considerations when performing an iSCSI installation:
An iSCSI boot on SPARC platforms is supported with OpenBoot level 4.31 or later, and does not require a specific NIC. The boot command in OpenBoot takes a series of keywords to identify the destination iSCSI target or uses the parameters stored in the network-boot-parameters NVRAM variable. The command uses the format boot net:keyword=value.
On x86 platforms, the host that is being booted must use NICs that are iSCSI Boot Firmware Table (iBFT) capable or have a main board BIOS that is iBFT capable. To configure iSCSI boot properly, refer to the documentation for your specific NIC hardware.
