    Try this:
    [root@mine]: /root # uname -a
    SunOS mine 5.10 Generic_137111-01 sun4v sparc SUNW,SPARC-Enterprise-T5220

    1)  Display your boot-device information

    [root@mine]: /root # eeprom boot-device
    boot-device=/pci@0/pci@0/pci@2/scsi@0/disk@0,0:a disk net

    2) Change it to a simple pattern and display it again

    [root@mine]: /root # eeprom boot-device=pepe
    [root@mine]: /root # eeprom boot-device

    3) If we want a complex pattern, put double quotes but only on the string, and then display it again.

    [root@mine]: /root # eeprom boot-device="/pci@0/pci@0/pci@2/scsi@0/disk@0,0:a disk net"
    [root@mine]: /root # eeprom boot-device
    boot-device=/pci@0/pci@0/pci@2/scsi@0/disk@0,0:a disk net
