Cleaning Cartridge Presence Indicators in the Tape Library

Edit online
The tape library can monitor up to 100 cleaning cartridges in the physical library for any supported method of cleaning. See the section about cleaning the drive in the TS4500 Introduction and Planning Guide. The presence of a library-monitored cleaning cartridge is indicated in the Storage Element descriptor of Read Element Status data as follows:
  • EXCEPT bit is set to 1
  • FULL bit is set to 1
  • ASC/ASCQ field is set to 30/03
  • The first, second, and third characters of the Primary Volume Tag field, if available, are set to CLN in ASCII
In addition, when automatic cleaning is enabled, the ACCESS bit is set to 0; when automatic cleaning is disabled, the ACCESS bit is set to 1.

While an automatic cleaning is in progress, movement of the cleaning cartridge is not reflected in the element descriptors. The Storage Element descriptor reported for the cleaning cartridge slot does not change while the cleaning cartridge is in a drive. Similarly, the Data Transfer Element descriptor reported for the drive that is cleaning does not change (indicates the FULL bit set to 0).

While a host cleaning is in progress, movement of the cleaning cartridge is reflected in the element descriptors in the same manner as for a data cartridge.
