Example -- Enabling a Slice in a Submirror

# metareplace -e d11 c1t4d0s7
d11: device c1t4d0s7 is enabled

The mirror d11 has a submirror that contains slice, c1t4d0s7, which had a soft error. The metareplace command with the -e option enables the errored slice.

If a physical disk is defective, you can either replace it with another available disk (and its slices) on the system as documented in "How to Replace a Slice in a Submirror (Command Line)", or repair/replace the disk, format it, and run metareplace with the -e option as shown in this example.
