Abstract
A method begins by a requesting entity sending a normal data segment access request to first and second groups of storage units of a dispersed storage network. The method continues with the requesting entity sending a group failure data segment access request to the first group of storage units when the second group of storage units has less than a decode threshold number of encoded data slices of a set of encoded data slices available. When the second group of storage units has reestablished that the at least the decode threshold number of encoded data slices is available, the method continues with the requesting entity sending a re-integration data segment write request to the first and second groups of storage units and sending a re-integration data segment read request to the first group of storage units.
