Please show us the volume layout : vxprint -htg (diskgroup)

On the CVM master node (run "vxdctl -c mode" to confirm node is master), run "vxdiskadm" and choose option 5 = "Replace a failed or removed disk".

Hi ,

Pls find the diskgroup details. see atttached

We have a stroage migration on SAN , Disk has been shared  and mirrored on different sites , so we need to replace with the NEW LUN of stroage ,
