Abstract
Described are techniques used in defining and maintaining group data used by multiple host systems. Group data is stored in a distributed fashion on one or more data storage systems. If a device of a data storage system belongs to a group, group data for that group is stored on that data storage system. Group data changes made by one host are communicated to the other hosts by accessing a common data area on each data storage system using a daemon executing on each host. Remotely mirrored groups may be defined on a remote data storage system. A remote mirror of a group includes group data modified in accordance with a point of view of the remote data storage system and a remote host.
