After a switchover, the host no longer has access to data on the LUNs that are in NVFAIL states. You must perform a number of actions before the database has access to the LUNs.
Before you begin
The database must not be running.
- Clear the NVFAIL state on the affect volume that hosts the LUNs by resetting the -in-nvfailed-state parameter of the
volume modify command.
- Bring the affected LUNs online.
- Examine the LUNs for any data inconsistencies and resolve them.
This might involve host-based recovery or recovery done on the storage controller using SnapRestore.
- Bring the database application online after recovering the LUNs.
