"LUN assignments on this target have changed" kernel warning messages after LUN reconfiguration at storage array.
Issue
- Should I be concerned about messages indicating "LUN assignments on this target have changed"?
-
Whenever LUNs are reconfigured on the storage array, the kernel reports the following warnings:
kernel: sd 1:0:5:58: Warning! Received an indication that the LUN assignments on this target have changed. The Linux SCSI layer does not automatically remap LUN assignments.
