Changing An Existing Configuration

Most configuration changes to existing units wipe out existing information on the drives. There are a few exceptions. For example, you can enable or disable the write cache, and you can change whether rebuilds will continue in the event of ECC errors, without losing your data.

If you want to make changes to the configuration of a unit, you must first delete it and then recreate it with new drives. There is no way to modify an existing unit without overwriting data on the drives involved.

To change an existing configuration

  1. Back up the data that you want to retain from the unit you will reconfigure.
  2. Delete the existing unit, using either 3BM or 3DM. For more information, see Deleting a Unit.
  3. Create a new unit, following the instructions under Creating a New Unit.
  4. Reboot your system and then partition and format the new units, whether RAIDs or Single Disks.
  5. Restore from backup any data saved from previous unit.
