To install Oracle Solaris without using an IPS AutoInstall server on the network, you can use Oracle Solaris media in a DVD drive. The DVD drive can be attached to a USB port. You also can boot from an ISO image copied to a DVD disk, hard drive, or SSD.
You can install Oracle Solaris 11.3 OS on this server from an image copied to a USB flash drive. That USB image is available for download at the same location as the ISO images http://www.oracle.com/technetwork/server-storage/solaris11/downloads/index.html.
You also can create a persistent device alias for a device connected to a USB port. The simpler alias name remains available for future installation or boot operations.
For more information about installing Oracle Solaris and creating persistent device aliases, refer to Installing Oracle Solaris 11.3 Systems at:
http://docs.oracle.com/cd/E53394_01.
You can boot Oracle Solaris 11.3 from drives installed in the server (hard drive or SSD) or from devices connected to a USB port.
For the path to identify a USB port in a boot command, refer to the list of devices output by the show-dev OpenBoot command.
