When you stop mirrored protection, one unit from each mirrored pair is unconfigured. Before you can stop mirrored protection for a disk pool, at least one unit in each mirrored pair in that disk pool must be present and active. To control which mirrored unit of each pair is unconfigured, you may suspend the storage units that you want to become unconfigured. For units that are not suspended, the selection is automatic.
If you want to stop mirroring on an independent disk pool that is unavailable, you can do so when your system is fully restarted. For all other disk pools, you need to restart your system to the dedicated service tools (DST) mode before stopping mirrored protection.
Mirrored protection is local to a single server and is distinct from cross-site mirroring or geographic mirroring.
