When attempting to set up DAOS on AIX server we ran in to the following error in the log The database /lotus/domino/data/mail/xxxxxxxxx.TMP was unable to write to file /DAOS/0001/F0CEB8D561FA1F89852575F20069C85F47F0CEB8D561FA1P.nlo: File cannot be created.
Follow the below steps to resolve the same.

3. Remove all DAOS directories
