6027-499 [X] An unexpected Device Mapper path dmDevice (nsdId)
has been detected. The new path does not have a Persistent Reserve
set up. File system fileSystem will be internally
unmounted.
Explanation
A new device mapper path is detected or a previously failed path is activated after
the local device discovery has finished. This path lacks a Persistent Reserve, and cannot be used.
All device paths must be active at mount time.
User response
Check the paths to all disks making up the file system.
Repair any paths to disks which have failed. Remount the file system.
