Recovering LUNs in NVFAIL states after switchover

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.

  1. Clear the NVFAIL state on the affect volume that hosts the LUNs by resetting the -in-nvfailed-state parameter of the volume modify command.
  2. Bring the affected LUNs online.
  3. 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.

  4. Bring the database application online after recovering the LUNs.
