6027-919 Replication parameter range error (value, value).
Explanation
Similar to message 6027-918. The (a,b) numbers are the allowable
range of the replication attributes.

You may want to create a new file with the desired attributes and then
copy your data to that file and rename it appropriately. Be sure that there
are sufficient disks assigned to the pool with different failure groups to
support the desired replication attributes.
