Procedure: Removing system data from a node canister

This procedure guides you through the process to remove system information from
a node canister. The information that is removed includes configuration data, cache
data, and location data.
About this task
Attention: If the enclosure reaches a point where the system data is not available
on any node canister in the system, you have to perform a system recovery. This
recovery is an extended service action and might not be able to recover all of your
volumes. Do not perform this action to remove the system data from a node unless
there is a node canister with saved system information in the enclosure. Do not
remove the system data from a node unless instructed to do so by a service
procedure.
Procedure
1. Start the service assistant on the node canister.
2. Use the service assistant node action to hold the node in service state.
3. Use the Manage System option to remove the system data from the node.
Results
The node restarts in service state. When you want the node canister to be active
again, use the service assistant home page action to leave service state.

Procedure: Deleting a system completely

This procedure guides you through the process of completely removing all system
information. When the procedure is finished, the system performs like a new
installation.
About this task
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.
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.
Procedure
1. Start the service assistant on one of the node canisters.
2. Use the service assistant node action to hold the node in service state.
3. Use the Manage System option to remove the system data from the node.
4. Perform the previous steps on the second node canister in the enclosure.
