Dynamic storage device libraries
View Patent ↗Tape device paths, library slots and drive information are automatically collected by agents at nodes in a library cluster. The information is reported to a central server database. The central server accesses the information and maps tape devices to path information so an administrator may easily have access to configuration information for the tape device cluster. When a tape device cluster is updated, for example through changes to a device, an added device, device failure or some other reason, the change is detected and the cluster configuration is automatically updated.
1. A method for automatically tracking tape drive paths, the method comprising:
receiving tape drive path information at a central server, wherein the received tape drive path information identifies a particular tape drive and a slot location that corresponds to the particular tape drive;
storing the tape drive path information at the central server; and
providing the tape drive path information to a node, wherein data may be retrieved from the slot location of the particular tape drive by the node in response to the tape drive path information.
2. The method of claim 1 , wherein tape drive path information includes vendor, product, or serial number.
3. The method of claim 1 , wherein tape drive information includes vendor, product or serial number of the particular tape drive that resides in a library slot.
4. The method of claim 1 , wherein the tape drive path information is retrieved by a library control program.
5. The method of claim 1 , wherein tape drive information is retrieved by a device control program.
6. The method of claim 1 , further comprising:
receiving updated tape drive path, updated tape drive slot, or updated tape drive information; and
automatically updating the mapping based on the updated information.
7. A non-transitory computer readable storage medium having embodied thereon a program, the program being executable by a processor to perform a method for tracking tape drive paths, the method comprising:
receiving tape drive path information at a central server, wherein the received tape drive path information identifies a particular tape drive and a slot location that corresponds to the particular tape drive;
storing the tape drive path information at the central server; and
providing the tape drive path information to a node, wherein data may be retrieved from the slot location of the particular tape drive by the node in response to the tape drive path information.
8. The non-transitory computer readable storage medium of claim 7 , wherein the tape drive path information includes vendor, product or serial number.
9. The non-transitory computer readable storage medium of claim 7 , wherein tape drive information includes vendor, product or serial number of the particular tape drive that resides in a library slot.
10. The non-transitory computer readable storage medium of claim 7 , wherein the tape drive path information is retrieved by a library control program.
11. The non-transitory computer readable storage medium of claim 7 , wherein tape drive information is retrieved by a device control program.
12. The non-transitory computer readable storage medium of claim 7 , further comprising:
receiving updated tape drive path, updated tape drive slot, or updated tape drive information; and
automatically updating the mapping based on the updated information.
