Hi, I'm getting error message "Disk structure is corrupt or unreadable" when trying to access a LUNs on FAS2040. What could be the problem?

Hi,

Can you create a clone from a snapshot of the volume and try to mount that Lun?

Did someone do something to the disk - i.e. Resize it?  Is it Windows?  Can you mount the lun from a different machine?

They were try to provision the same LUNs to different hosts. I can't find snap shots! Snap shots were not enabled!

You can refer to the official case to see if it helpshttps://kb-cn.netapp.com/on-prem/ontap/da/SAN/SAN-KBs/How_to_troubleshoot_when_LUNs_are_reported_missing_on_host_end 

It is also possible that someone has adjusted the lun size, or other operations have taken the lun or volume offline
