Abstract:
A method for dispersed storage network (DSN) begins by detecting a memory error associated with a memory device of a storage unit. The method continues by identifying an error descriptor code based on the detected memory error. The method continues by determining whether to perform an intermediate action based on the error descriptor code. The method continues, when not performing the intermediate action, by issuing memory status information to the DSTN managing unit. The method continues, when performing the intermediate action, by performing the intermediate action to produce an action result. The method continues by determining whether the memory device is to remain in service based on one or more of the action result and the error descriptor code and, when the memory device is not to remain in service, issuing further status information to the DSTN managing unit to indicate the failed status indicator.
