Steps
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.
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, the host application might lose data because the storage
array will not be accessible.
2.
If the storage array participates in a mirroring relationship, stop all host I/O operations on the
secondary storage array.
3.
Wait for any data in cache memory to be written to the drives.
The green Cache Active LED (1) 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.
4.
From the Home page of ThinkSystem System Manager, select View Operations in Progress.
5.
Wait for all operations to complete before continuing with the next step.
7.2.4. Step 4: Change the feature pack
Change the feature pack to convert the host protocol of the baseboard host ports, the IB HIC ports,
or both types of ports.
