The following sections describe how to boot from SCSI devices:
You can boot any virtual LUN whose associated physical LUN references a SCSI device type that is bootable by OBP, such as CD, DVD, or disk.
Before you issue the boot command at the OpenBoot PROM prompt, run the probe-scsi-all command to find the guest domain's virtual SCSI HBAs and associated virtual LUNs.
The following annotated example highlights the relevant parts of the output:
{0} ok probe-scsi-all /virtual-devices@100/channel-devices@200/scsi@0Line 1 vHBA TPORT-PHYS: w200200110d214900Line 2 LUN: 1 Disk VLUN 2097152 Blocks, 1073 MB LUN: 0 Disk VLUN 32768000 Blocks, 16 GBLine 3
This example probe-scsi-all output shows one virtual SCSI HBA instance (scsi@0) that has two LUNs that are of type disk.
To boot from a specific virtual LUN, manually compose the device path to pass to the boot command. The device path has this syntax:
vhba-device-path/disk@target-port,lun:slice
To boot from the LUN on Line 3, you must compose the device path as follows:
Take the value of target-port from Line 2
Take the value of vhba-device-path from Line 1
The following is the resulting device path:
/virtual-devices@100/channel-devices@200/scsi@0/disk@w200200110d214900,0
You can pass this device path to the OBP boot command as follows:
{0} ok boot /virtual-devices@100/channel-devices@200/scsi@0/disk@w200200110d214900,0
You can boot from a SCSI digital versatile disc (DVD) drive to install the guest domain from that DVD.
The following example shows the configuration of a virtual SCSI HBA that has a SCSI DVD device attached to the primary domain.

From the gdom domain console, probe the SCSI devices and boot from the DVD.
