The OpenBoot firmware starts the OS, validates installed hardware, and can be used for other server administration tasks below the OS level. Some devices contain firmware written in the FCode language that enable additional commands that can be entered at the OpenBoot prompt (ok).
New OpenBoot properties are available on this server to accomodate booting an iSCSI device over IB. Also, a new OpenBoot variable has been added.
boot-pool-list - Lists device paths to OpenBoot accessible storage devices that comprise a boot pool. These are the devices that Oracle Solaris uses when booting. You can view this property with the .properties command under the /chosen node at the OpenBoot prompt.
tboot-list - Lists storage devices that include fall back images. You can view this property with the .properties command under the /chosen node at the OpenBoot prompt.
os-root-device - Defines devices and root file systems for root pools. This is a nonvolatile variable that you can view using the printenv command at the OpenBoot prompt or using the eeprom command at the Oracle Solaris prompt.
