scrub: resilver completed after 0h10m with 0 errors on Thu Mar 11 11:27:22 2010
- Apply boot blocks to the second disk after resilvering is complete.
sparc# installboot -F zfs /usr/platform/`uname -i`/lib/fs/zfs/bootblk /dev/rdsk/c1t1d0s0
x86# installgrub /boot/grub/stage1 /boot/grub/stage2 /dev/rdsk/c1t1d0s0
- Verify that you can boot successfully from the second disk.
- Set up the system to boot automatically from the new disk, either by using the eeprom command, the setenv command from the SPARC boot PROM. Or, reconfigure the PC BIOS.
