Abstract
A method includes receiving a humidity level in a tape library and determining whether the humidity level is in a predefined range indicative of safe operation. In response to determining that the humidity level is in the predefined range, the method includes allowing performance of operations on magnetic recording tapes. In response to determining that the humidity level is not in the predefined range, the method includes preventing performance of the operations on magnetic recording tapes. A drive-implemented method includes detecting a humidity level within a housing of a tape drive and determining whether the humidity level is in a predefined range indicative of safe operation.
Claims24
A method, comprising:
- receiving a humidity level in a tape library;
- determining whether the humidity level is in a predefined range indicative of safe operation for tape drives and/or tape media in the tape library;
- in response to determining that the humidity level is not in the predefined range, preventing performance of operations on magnetic recording tapes for at least a predefined acclimation period;
- and
- after preventing performance of operations on magnetic recording tapes,
- overriding a tape drive which alternates between humidity levels in the predefined range and humidity levels outside the predefined range until the humidity level in the drive reaches a steady state for a period of time at least equal to the entire predefined acclimation period.
A system, comprising:
- a processor;
- and
- logic integrated with the processor, executable by the processor, or integrated with and executable by the processor, the logic being configured to:
- receive a humidity level in a tape library;
- determine whether the humidity level is in a predefined range indicative of safe operation for tape drives and/or tape media in the tape library;
- in response to determining that the humidity level is not in the predefined range, prevent performance of operations on magnetic recording tapes for at least a predefined acclimation period;
- and
- after preventing performance of operations on magnetic recording tapes, overriding a tape drive which alternates between humidity levels in the predefined range and humidity levels outside the predefined range until the humidity level in the drive reaches a steady state for a period of time at least equal to the entire predefined acclimation period.
A computer program product, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a computer to cause the computer to:
- receive, by the computer, a humidity level in a tape library;
- determine, by the computer, whether the humidity level is in a predefined range indicative of safe operation for tape drives and/or tape media in the tape library;
- in response to determining that the humidity level is not in the predefined range, prevent, by the computer, performance of operations on magnetic recording tapes for at least a predefined acclimation period;
- and
- after preventing performance of operations on magnetic recording tapes, overriding a tape drive which alternates between humidity levels in the predefined range and humidity levels outside the predefined range until the humidity level in the drive reaches a steady state for a period of time at least equal to the entire predefined acclimation period.
