When I/O access is slow
Check the following points: When the cause is not identified, contact your maintenance engineer.
• Check that the ambient temperature does not exceed the operating environment conditions.
If so, Nearline SAS disk performance may be reduced.
• Click the icon of each part in the Storage System Status screen of ETERNUS Web GUI to
check if an abnormality is detected in ETERNUS DX Disk storage system parts.
If an abnormality is detected, contact your maintenance engineer.
• Check the controller status.
When the controller fails, the data in cache memory is directly written to the disks. This
causes temporary performance degradation.
When the controller fails, contact your maintenance engineer.
