Caution
• When the ETERNUS DX is rebooted or a controller firmware is applied, the performance monitoring
process is stopped. To continue collecting performance data, start the performance monitoring
process.
• If performance monitoring is started from ETERNUS SF Storage Cruiser, ETERNUS Web GUI or
ETERNUS CLI cannot stop the process.
• If performance monitoring is started from ETERNUS Web GUI or ETERNUS CLI, the process can be
stopped from ETERNUS SF Storage Cruiser.
