We are running esxi 5.0.0 469512
Local Datastore 1.80 TB
When I run the below command, I get a degraded status for the local datastore.
I checked the raid and the disk are reporting being ok.

Welcome to the Community,
in this case "Degraded" is not really correct. Volumes on this type of RAID controller (and other controllers too) are detected as external storage. That's likely the reason why the hypervisor's logic shows each LUN with less than 2 paths as "degraded", although it actually is not.

So this is a false positive, right?
I just want to be sure before I put any sort of data on it.
The server is a HP ProLiant ML350 G6
Yes, if there is only a single path to a target the status shows up as "Degraded", rather than "On" for targets with 2 or more paths.
I've just double-checked this on one of our HPE server.
