Abstract

Claims (16)

1. A system comprising:

one or more tape drives that are each configured to read and write to a tape;

one or more physical storage slots that are each configured to store a tape;

one or more physical import/export (I/E) slots that are each configured to receive or eject a tape being imported into or exported out of the system;

one or more processors; and

a memory coupled to the processors comprising instructions executable by the processors, the processors being operable when executing the instructions to:

maintain one or more logical storage elements that are each configured to be associated with one or more of the physical storage slots;

maintain a plurality of logical I/E elements that are each configured to be associated with one or more of the physical TIE slots; and

in response to a request by an initiator to export a particular tape stored in a particular physical storage slot that is associated with a particular logical storage element:

identify a particular physical I/E slot;

determine that a particular one of the plurality of logical I/E elements is available, the particular logical I/E element being available when it is not currently bound to any one of the one or more of the physical I/E slots;

bind the particular logical I/E element with the particular physical I/E slot to which the particular tape will be transported;

communicate, to the initiator, the particular logical I/E element bound to the particular physical I/E slot to which the particular tape will be transported; and

cause the particular tape to be transported to the particular physical I/E slot.

2. The system of claim 1 , wherein the initiator is an application.

3. The system of claim 1 , wherein the processors are further configured to report a number of available I/E elements to the initiator that includes the available logical I/E elements.
