Stop host I/O
You must stop all I/O operations from the host before converting the protocol of the host ports. You cannot
access data on the storage array until you successfully complete the conversion.
Step 1. 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,
the host application might lose data because the storage array will not be accessible.
Step 2. If the storage array participates in a mirroring relationship, stop all host I/O operations on the
secondary storage array.
Step 3. Wait for any data in cache memory to be written to the drives.The green Cache Active LED on the
back of each controller is on when cached data needs to be written to the drives. You must wait for
this LED to turn off.
