Why does one node in a cluster report the cache disk of the alternate node as Unavailable

Hi

Anyone able to explain whats going on with the Cache Disks ...

I have noticed with our setups that one node within a cluster always shows one of the internal disks on the opposite node as follows.

Node A reports  <nodename>:HDD2    Cache  "Unavailable (Private to cluster peer)" configuration->storage (device status section)

Node A reports disk unavailable under configuration->storage

Node A reports both HDD2 and HDD3 type as "Cache" in Maintenace->Hardware->details

Node B reports "No device faults have been detected in the storage pool" configuration->storage

Node B HDD2 type is set to "peer" and HDD3 is set to "Cache" in  Maintenance->Hardware->details

Howdy, Stranger!
