ListProtectionDomainLevels

You can use the ListProtectionDomainLevels method to list the tolerance and resiliency levels of the storage cluster. Tolerance levels indicate the cluster's ability to continue reading and writing data in the event of a failure, and resiliency levels indicate the storage cluster's ability to automatically heal itself from one or more failures.

Parameter

This method has no input parameter.

Return values

This method has the following return values:

Name Description Type
protectionDomainLevels A list of the different protection domain levels, where each supplies the storage cluster's tolerance and resiliency information. protectionDomainLevel
