Failure abatement approach for failed storage units common to multiple vaults

Abstract:

A method includes detecting, by a vault management device, a failed storage unit common to a first vault and a second vault. The first vault is associated with a first set of storage units and the second vault is associated with a second set of storage units. The failed storage unit is in each of the first and second sets of storage units. The method further includes identifying a number of non-failed storage units of the first and second sets of storage units and comparing the number of non-failed storage units with first and second decode threshold numbers to determine a failure impact level. The first decode threshold number is associated with the first vault and the second decode threshold number is associated with the second vault. The method further includes determining a failure abatement approach based on the failure impact level and facilitating the failure abatement approach.
