Fault Levels
Storage system faults are classified into minor faults, major faults, and critical faults in terms of fault impact.
Table 2-2 describes storage system fault levels and characteristics.
Fault Level |
Characteristic |
Handling Measure |
|---|---|---|
Minor |
The faults have no adverse impact on storage system performance and host services, such as failure to log in to OceanStor DeviceManager, failure to log in to or activate a serial port. |
Common troubleshooting |
Major |
Host I/Os are delayed or host services are interrupted because storage system performance deteriorates, such as interface module faults, failure of an application server to load the multipathing software after the server is restarted. |
Emergency handling |
Critical |
Some production systems are unavailable and the risk of some data loss is high or some data has been lost, such as controller faults. |
