Zusammenfassung:Providing multiple witnesses that manage resources for at least two different sites includes one of the sites choosing a particular one of the witnesses, the one of the at least two different sites confirming that the particular one of the witnesses is available to manage resources, the one of the at least two different sites communicating with other ones of the at least two different sites to determine if the particular one of the witnesses is acceptable to the other ones of the at least two different sites, and choosing the particular one of the witnesses in response to the particular one of the witnesses being available to manage resources and the particular one of the witnesses being acceptable to all of the other ones of the at least two different sites. The managed resources may correspond to data storage and the sites may be mirrored storage devices.
