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.
Possible data loss – If you continue this procedure while I/O operations are occurring, you might lose data.
Attention:
5. If the storage array participates in a mirroring relationship, stop all host I/O operations on the secondary storage array.
6. Wait for five minutes to allow any data in cache memory to be flushed to disk.
7. From the title bar of the Array Management Window, select Monitor > Reports > Operations in Progress.
8. Wait for all operations shown on the Operations in Progress window to complete before continuing with the next step.
