6027-3402 [X] An unexpected device mapper path dmDevice (nsdId) was detected. The new path does not have Persistent Reserve enabled. The local access to disk diskName will be marked as down.
Explanation
A new device mapper path was detected, or a previously
failed path was activated after the local device discovery was 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 in the file system.
Repair any failed paths to disks then rediscover the local disk access.
