To find out all the disks whose UDID is mismatched by running the below commands. 

# vxdisk -q list | cut -f1 -d' ' | xargs -i vxdisk -v list {} | egrep '^Device|^disk:|^udid:|udid_asl' | sed 's/^udid: //' | sed 's/.udid_asl=//' | uniq –c

How to update disks UDID in VxVM 

You have to update udid on all the disks which are obtained in the above step.

# vxdisk updateudid  <disk>    

Once UDID gets updated it will mark disks as a cloned tag but actually, they may not be a real clone disk thus we need to set clone off for disks using the below command.
