IBM Storwize / Remove all system information
This procedure guides you through the process to completely remove all system information. When the procedure is finished, the system performs like a new installation.
Attention: This procedure makes all the volume data that you have on your system inaccessible. You cannot recover the data. This procedure affects all volumes that are managed by your system, which includes the drives in the control enclosure, in the expansion enclosures, and on the managed disks on external storage systems. The only volumes not affected are image mode volumes on external storage systems.
Do not continue unless you are certain that you want to remove all the volume data and configuration data from your system. This procedure is not used as part of any recovery action.
There are two stages to this procedure. First, the node canisters are reset. Second, the enclosure data is reset.

- On one node in every enclosure, open the service assistant Configure Enclosure and select the Reset System ID option.This action causes the system to reset.
- Power each enclosure off and on before creating a system.
