I just did this, after installing osol-0906-x86, following the instructions here: http://darkstar-solaris.blogspot.com/2008/09/zfs-root-mirror.html In my case, the system had two identical internal disks attached to a SATA controller. Here's how it went: o Label second mirror side mills at amd:~$ prtvtoc /dev/rdsk/c8d0s2 | fmthard -s - /dev/rdsk/c9d0s2 fmthard: New volume table of contents now in place. o Attach second side mills at amd:~$ zpool attach rpool c8d0s0 c9d0s0 invalid vdev specification use '-f' to override the following errors: /dev/dsk/c9d0s0 overlaps with /dev/dsk/c9d0s2 mills at amd:~$ zpool attach -f rpool c8d0s0 c9d0s0 Please be sure to invoke installgrub(1M) to make 'c9d0s0' bootable. mills at amd:~$ zpool status pool: rpool state: ONLINE status: One or more devices is currently being resilvered.
