We run a 3-node NW6.5 SP3 cluster.

While viewing the RAID Device info for the cluster partition, via NSSMU,
we noticed the following

Master node RAID Status - 100% Remirrored
Secondary node - 99% Remirrored
Tertiary node - 99% Remirrored

As an aparent rule, the master node (whichever that may be) always reads
100% Remirrored.

Why do the the other nodes not read 100% also - is this by design and got
something to do with the master node having control?
