Named mount optimization for virtual tape systems

摘要

Embodiments are described for named mounts in a virtual tape engine (VTE) system. A system maintains a file list of named volumes for each of the VTEs. When named mount requests are received, the system searches the file list for the named volume rather than searching through each of the file systems for each of the VTEs. When the volume name is found on a file list, the VTE for the volume name is identified and the mount request can be completed.

主权项

1. A method comprising:
forwarding scratch volumes and named volumes received from a mainframe processor for storage on a plurality of file systems by a plurality of virtual tape engines; creating file lists stored on each of the virtual tape engines which include volume names of the scratch volumes and the named volumes on the plurality of file systems; polling the plurality of file systems by each of the virtual tape engines for changes in the named volumes and the scratch volumes on the file systems; and updating the file lists for each of the plurality of virtual tape engines based upon the changes in the named volumes and the scratch volumes on the file system.
