6027-3030 [E] There must be at least number non-spare
pdisks in declustered array declusteredArrayName for
configuration data replicas.
Explanation
A delete pdisk or change of spares operation failed
because the resulting number of non-spare pdisks would fall below
the number required to hold configuration data for the declustered
array.
User response
Add additional pdisks to the declustered array.
If replacing a pdisk, use mmchcarrier or mmaddpdisk
--replace.
