How are the fault severity levels defined in the storage system?

2

There are three levels of fault information for storage systems according to the impact on storage systems and their services:
? Critical: The fault affects the system functions, and immediate measures should be taken to handle the fault. For example, a device or resource cannot be used and needs to be recovered. Even if the fault does not occur in working hours, it needs to be handled immediately.
? Major: The fault affects the system functions, and measures should be taken to handle the fault. For example, the service quality of a device or resource degrades, and the device or resource needs to be recovered to the normal state. The fault needs to be handled immediately.
? Warning: The fault does not affect the system functions but raises hidden risks in the storage system. The fault needs to be handled according to the actual situation.
You can set the fault notification methods on the ISM interface. Once a critical, major, or warning fault occurs in the storage system, the system notifies users through short messages or emails, and users can monitor and manage the storage system in a convenient way.

The administrator can run the command-privilege level level view view-name command-key command to set the command level in a specified view. This configuration enables a lower-level user to use some high-level commands, or raises the command level to improve device security.

NOTICE:

It is recommended that you do not change the default command level without the guidance of professionals. Otherwise, it may result in inconvenience for operation and maintenance and bring about security problems.
