Abstract
A data processing system using a client-server configuration includes a method and apparatus for simultaneously generating multiple copies of data sets in multiple storage pools. Simultaneous copies of data sets may be made for storage pools having LAN-free paths in addition to storage pools having only access from a LAN path.
Claims2
In a data processing system, a method for creating copies of data sets in a plurality of storage pools having multiple destinations, comprising:
- receiving a storage request from a client;
- defining a primary storage pool;
- selecting a defined copy storage pool;
- in response to a selected copy storage pool which is local, obtaining a mount point, opening a volume in the selected copy storage pool, adding the mount point to the list of destinations;
- and,
- in response to a selected copy storage pool which is remote, contacting the remote server, creating a local mount point to reference the entire remote list on the server, requesting a remote mount point, request remote server to open a volume.
An article of manufacture for use in a data processing system able to store backup copies of a data set in storage pools having multiple destinations, said article of manufacture comprising:
- a computer usable medium tangibly embodying a program of executable computer instructions which cause said data processing system to execute steps comprising:
- receiving a storage request from a client;
- defining a primary storage pool;
- selecting a defined copy storage pool;
- in response to a selected copy storage pool which is local, obtaining a mount point, opening a volume in the selected copy storage pool, adding the mount point to the list of destinations;
- and,
- in response to a selected copy storage pool which is remote, contacting the remote server, creating a local mount point to reference the entire remote list on the server, requesting a remote mount point, request remote server to open a volume.
