StorageTek 6 manual Identifying Cleaning Cartridges, Notes

Once auto-cleaning is activated, the CLean command can be issued to initiate cleaning of specified drives on specified hosts.

An example of issuing the CLean command is:

CLEAN 582 HSTA

Notes:

1.The MNTD AUtocln command must be set to ON before attempting to use the CLean command.

2.The CLean command sets the transport to ‘‘needs cleaning’’ status. The cleaning process is not initiated until the next mount is issued against the transport. Refer to the HSC Operator’s Guide for an explanation of the CLean command.

Identifying Cleaning Cartridges

Cleaning cartridges are identified to the HSC by a unique three-character alphabetic prefix in their volser. All cartridges identified with that prefix make up a pool of cleaning cartridges in each LSM.

The parameter CLNPRFX, contained in the LIBGEN SLILIBRY macro, specifies the volser prefix for cleaning cartridges. CLNPRFX must be three alphabetic characters, and identifies cleaning cartridges associated with the library. The default is CLN. Refer to ‘‘SLILIBRY Macro’’ in the HSC Installation Guide for additional information.

Notes:

1.Any cartridges identified by the cleaning prefix are treated exclusively as cleaning cartridges; they cannot be scratched or initialized by HSC utilities.

2.Extra overhead can be avoided if the range of cleaning cartridge volsers in an LSM and ACS is both narrow and dense. For example, if three cleaning cartridges are in a single LSM, labels of CLN020, CLN021 and CLN022 would cause less processing overhead than if they were labeled CLN001, CLN501 and CLN901.

3.The cleaning prefix can be changed using the SET CLNPRFX utility. However, before the cleaning prefix is changed, all cleaning cartridges must be ejected from all ACSs. See the description of the SET utility for the complete procedure. Cleaning Media and Drive Compatibility Tape transports must be cleaned with cleaning cartridges of a compatible cleaning media type. Longitudinal transports must be cleaned with longitudinal cleaning media, RedWood transports must be cleaned with helical cleaning media (DD3D), and 9840 transports must be cleaned with 9840 cleaning media (STK1U).

4.Different cleaning cartridge media types may have different maximum cleaning usage limits. Grouping cleaning cartridges of different media types into different volser ranges makes it easier to specify these limits with the
