IBM support might ask you to collect trace files and dump files from your system
to help them resolve a problem.
The management GUI and the service assistant have features to assist you in
collecting the required information. The management GUI collects information
from all the components in the system. The service assistant collects information
from a single node canister. When the information that is collected is packaged
together in a single file, the file is called a snap.
