The host type for my host (rman-ss-03) was set to "Linux", BTW.

...
      STORAGE ARRAY
         Default type:                Windows

         Default Group

         Host:                        rman-ss-03
            Host type:                Linux
            Interface type:           SAS
               Host port identifier:  5a:4b:ad:b0:44:65:8e:00
               Alias:                 Port0
               Host port identifier:  5a:4b:ad:b0:44:65:60:00
               Alias:                 Port1
...

Regardless, I changed the default host type to "Linux" and rebooted.

No change in behavior. The "phantom" LUNs are still listed and the 
errors are still being logged.
