I don't think this is what you want. Notice that it is in the process of
replacing c1t2d0 with emcpower0a. Once the replacing operation is
complete, c1t2d0 will be removed from the configuration.
You've got two options. Let's say your current mirror is c1t2d0 and
c1t3d0, and you want to replace c1t3d0 with emcpower0a.
Option one: perform a direct replace:
# zpool replace mypool c1t3d0 emcpower0a
Option two: remove c1t3d0 and add in emcpower0a:
# zpool detach mypool c1t3d0
# zpool attach mypool c1t2d0 emcpower0a
Do not mix these two options, as you showed in your email. Do not perform
a 'detach' followed by a 'replace'. This is mixing your options and you
will end up with a config you were not expecting.
