Managing mirrored protection

 

Refer to this topic to see the tasks that you can perform to manage your disk protection activities.

• Stopping mirrored protection
  When you stop mirrored protection, one disk unit from each mirrored pair is unconfigured. Before you can stop mirrored protection for a disk pool, at least one disk unit in each mirrored pair in that disk pool must be present and active.

• Suspending mirrored protection
  If a disk unit in a mirrored pair fails, you need to suspend mirroring to repair or replace it.

• Enabling remote load source mirroring
  Enabling remote load source mirroring makes it possible for the two disk units of the load source mirrored pair to be on different IOPs or system buses. Remote load source mirroring allows you to protect against a site disaster by dividing the disk storage between the two sites, mirroring one site to another.

• Finding remote buses
  If the buses are not labeled, you might need to manually trace the buses to see which connect to remote locations. You can also use the Hardware Service Manager to determine which buses go to which expansion units.

• Changing remote bus resource names
  After you determine which buses control remote disk units, use Hardware Service Manager to change the resource names of the remote buses.
