Abstract
A method for reserving a shared volume in a multiple node data storage system is disclosed. The method ensures that only one host at a time has access to the shared volume. As a result, the data/information stored in the shared volume cannot become corrupted due to multiple hosts accessing the shared volume at the same time through different nodes.
