When trying to create a VxFS file system from a newly created Disk Group and Volume under SUN cluster environment, we get the following error

# mkfs -F vxfs -o largefiles /dev/vx/rdsk/coredg/core_arch
UX:vxfs mkfs: ERROR: V-3-20003: Cannot open /dev/vx/rdsk/coredg/core_arch: No such device or address


newfs and dd command will give the same error "No such device or address"

Solution:

If the storage is already under SUN cluster control,  sync the vxdg with SUN cluster.

# scconf -c -D name=,sync

After the above step, we can create new VxFS file system and mount it successfully
