Absent, Ejected and Missing Cartridges

ACSLS reports three cartridge (volume) statuses:

  • missing

    The cartridge cannot be located in the library, and at least one recorded location for the cartridge cannot be searched because the LSM is offline or a drive is not communicating. The information about the cartridge has been retained.

  • absent

    The cartridge cannot be located in the library. All recorded locations for the cartridge have been searched, and the cartridge is not in any of them. The information about the cartridge is retained. If the cartridge is found or re-entered into the library (before the retention period expires), it is reactivated.

  • ejected

    The cartridge was ejected. The information about the cartridge is retained, and if the cartridge is found or re-entered (before the retention period expires), it is reactivated.

Cartridge (Volume) Status Reporting

ACSLS reports cartridges (volumes) with the status “missing", “absent," or “ejected," differently in response to ACSLS commands than it does in response to ACSAPI requests.

The information displayed in response to ACSLS commands identifies a cartridge as “missing", “absent", or “ejected."

However, the cartridge status information ACSLS displays in response to ACSAPI requests is governed by the following ACSLS dynamic variables:

  • missing

    • If the ACSLS dynamic variable ENABLE_STATUS_VOLUME_MISSING is TRUE, ACSLS reports: STATUS_VOLUME_MISSING.

    • If the ACSLS dynamic variable ENABLE_STATUS_VOLUME_MISSING is FALSE, ACSLS reports: STATUS_VOLUME_IN_TRANSIT.

  • absent

    • If the ACSLS dynamic variable ENABLE_STATUS_VOLUME_ABSENT is TRUE, ACSLS reports: STATUS_VOLUME_ABSENT

    • If the ACSLS dynamic variable ENABLE_STATUS_VOLUME_ABSENT is FALSE, ACSLS treats the volume as if it had been deleted from the ACSLS database and reports: STATUS_VOLUME_NOT_IN_LIBRARY.

  • ejected

    • If the ACSLS dynamic variable ENABLE_STATUS_VOLUME_EJECTED is TRUE, ACSLS reports: STATUS_VOLUME_EJECTED

    • If the ACSLS dynamic variable ENABLE_STATUS_VOLUME_EJECTED is FALSE, ACSLS treats the volume as if it had been deleted from the ACSLS database and reports: STATUS_VOLUME_NOT_IN_LIBRARY.

The ABSENT_VOLUME_RETENTION_PERIOD dynamic variable controls how long absent and ejected volumes are retained in the ACSLS database and specifies the number of days these volumes are retained. There are two special values:

  • The value 0 (zero) days specifies that volumes are deleted and will not be marked absent or ejected. (This is the behavior of ACSLS releases previous to ACSLS 6.1.)

  • The value 999 days specifies that absent and ejected volumes are retained forever in the database.
