Issue

After a disaster, the remote plex in a mirrored aggregate has a large number of failed disks

Example:
Aggregate aggr1_node01 (online, raid_dp, mirror degraded) (block checksums)
  Plex /aggr1_node01/plex0 (offline, failed, inactive, pool0)
    RAID group /aggr1_node01/plex0/rg0 (partial, block checksums)

      RAID Disk	Device   	HA  SHELF BAY CHAN Pool Type  RPM  Used (MB/blks)    Phys (MB/blks)
      ---------	------   	------------- ---- ---- ---- ----- --------------    --------------
