# REBOOT
metaattach d0 d11



Done!
# eeprom boot-device
boot-device=disk disk1

Use "prtconf -vp" to check default disk alias.
If boot-device is not set to backup mirror disk, proceed with follwing steps.
# eeprom use-nvramrc?=true
> We need to do is to set the “use-nvramrc = true” OBP variable so our modifications will be used when system is reboot.
> you can set dev alias if it is not set as below;
# eeprom nvramrc=”devalias rootdisk /pci@780/pci@0/pci@9/scsi@0/disk@0,0 devalias rootmirror /pci@780/pci@0/pci@9/scsi@0/disk@1,0″

> Then set boot-device as below;
# eeprom boot-device=”rootdisk rootmirror”
# reboot
