Attach disk to the ZFS root mirror pool

Having broke root mirror pool, trying to migrate it to RAID-Z to boot from (until I figured out, that booting from RAID-Z is not yet supported in Solaris, but works in Free-BSD - WTF!!?!?), I was forced to put disk back into root mirror pool...but failed. That`s what have I done to fix this:

-bash-3.00# zpool attach rpool c0t0d0 c0t1d0 cannot label 'c0t1d0': EFI labeled devices are not supported on root pools.

-bash-3.00# prtvtoc /dev/rdsk/c0t0d0s0 | fmthard -s - /dev/rdsk/c0t1d0s0 fmthard: New volume table of contents now in place. -bash-3.00# zpool attach rpool c0t0d0s0 c0t1d0s0 Please be sure to invoke installboot(1M) to make 'c0t1d0s0' bootable.



-bash-3.00# installboot -F zfs /usr/platform/`uname -i`/lib/fs/zfs/bootblk /dev/rdsk/c0t1d0s0

-bash-3.00# zpool status

pool: rpool

state: ONLINE

That`s it! Works, up and running.

PS - sun.com is gone...being an rational man I do believe, that Oracle will get most of Sun`s great engineers with Oracle`s sales managers (`cos Sun`s sales are the worst ever, and Johnny Schwartz should be banned from IT forever), and I wish that Solaris/Oracle will make an great deal. Godspeed!
