All IBM Cloud Object Storage Slicestor® devices that are
included in the Storage Pool first must be upgraded to ClevOS 3.4 or higher.
Slicestor® Data Evacuation follows this
simple workflow: Figure 1. Slicestor Data Evacuation State Diagram
Follow the steps that are outlined in Replace a Device in the Manager Administration
Guide.
When a Slicestor® device is replaced, data
evacuation starts and enters the Evacuating state. It can be paused and
resumed after it begins evacuation.
When all data is copied to the Destination Slicestor® device, the evacuation enters the final
Completed state.
Attention: Do not remove Slicestor®
devices during an evacuation.
If the Source Slicestor® device is reimaged or removed from the
System Manager before data evacuation is completed, all data slices that are not already evacuated
are lost. The data slices must be rebuilt.
If the Destination Slicestor® device is reimaged for any reason during
data evacuation, data slices that are already evacuated are not present and are lost. These data
slices must be rebuilt.
Do not remove or reimage any Slicestor® device that is involved in data
evacuation while it is in progress in a production environment.
For more information about the
Rebuilder process, see the Rebuilder Agent guidelines.
Note: Lists and reads are disabled on the Destination Slicestor® device during evacuation. It prevents the
Rebuilder process on other Slicestor® devices or
clients from gathering incomplete data.
