Removing old storage

After the mirroring process completes, you can remove the old storage.

To remove the old storage

  1. Break the mirror.
  2. Check the viability of the volume. Services do not need to be stopped during this phase.
  3. Clean up the mirror from the old disk (OLDDISK).
  4. Remove the old storage from the diskgroup.

The use of the backslash is necessary to override the significance of "!" to the bash Shell which is the default shell for root user. Without the "\", the bash ( or C Shell) command line interpreter would look for some history of command event.
