Messages are written to the console if any over-use cleaning cartridges are found in the
ACS, how many were found, and if an over-use cleaning cartridge has been kept in the
ACS. These messages help the operator manage cleaning cartridges in the ACS.
Managing Cleaning Cartridges
Appropriate numbers of compatible cleaning cartridges must be available to clean the
transports attached to an LSM. While there is no minimum number of cleaning cartridges,
optimally, each LSM should contain multiple cleaning cartridges for each type of transport
attached to the LSM. This ensures that automated cleaning avoids pass-thrus for cleaning
cartridges.
If all transports in an LSM are scheduled for cleaning at the same time (by a scheduled or
operator-entered CLean command), each LSM should contain one cleaning cartridge for
every tape transport attached to the LSM.
Managing cleaning cartridges is especially important when automatic ejection of over-use
cleaning cartridges has been disabled by the MNTD EJctauto command. On a regular
basis, these cleaning cartridges must be identified, ejected from the ACS, and replaced
with new cleaning cartridges.
Use the Volume Report utility to identify over-use cleaning cartridges. Select the cleaning
cartridges by volser range and sort the output by use:
The ‘‘Cln Use’’ column on the report identifies:
N = Not usable cartridges (including spent cleaning cartridges)
M = Over MAXclean, for over-limit cleaning cartridges
Spent and over-limit cleaning cartridges are also identified on the SLSCDATA flat file
requested by the VOLDATA parameter. Volume data is mapped by the SLUVVDAT
macro. Volumes that are not usable (i.e., spent) are identified by VOLNOUSE. The
MAXclean value that applies to a cleaning cartridge is carried in the VOLMXCLN field.
Manual Tape Transport Cleaning
If auto-cleaning is disabled, tape transports must be cleaned manually. This process can be
performed without entering the LSM.
Two methods that may be used to accomplish this task are:
• issue a Mount command to mount a cleaning cartridge on the transport. When
cleaning is complete, enter a DISMount command to remove the cleaning cartridge
from the transport.
• use an automated operations package to mount and dismount the correct cleaning
cartridge(s) on the transport(s). Coordination and setup is required to implement this
