4. Ensure that no I/O operations are occurring between the storage array and all connected hosts. For example, you can perform
these steps:
• Stop all processes that involve the LUNs mapped from the storage to the hosts.
• Ensure that no applications are writing data to any LUNs mapped from the storage to the hosts.
• Unmount all file systems associated with volumes on the array.
Note: The exact steps to stop host I/O operations depend on the host operating system and the configuration, which are
beyond the scope of these instructions. If you are not sure how to stop host I/O operations in your environment, consider
shutting down the host.
Attention: Possible data loss – If you continue this procedure while I/O operations are occurring, you might lose data.

If the storage array participates in a mirroring relationship, stop all host I/O operations on the secondary storage array.
