In addition to protecting database files and LUNs using the nvfail option, you can have Data ONTAP rename database files and LUNs that you want protected. Renaming database files and LUNs prevents the database from restarting automatically and gives you an opportunity to examine the files for inconsistencies before clients can access them.
Data ONTAP requires a file called /etc/nvfail_rename in which to put the names of the files you want protected.
For instructions about examining database file validity, see the documentation for your specific database software.
If your database uses LUNs, review the steps to make the LUNs accessible to the host after an NVRAM failure.
