Cleaning Cartridges

Cleaning cartridges have a unique 3-character alphanumeric prefix in their VOLSER (the
default is "CLN"). Cartridges with that prefix make up pools of cleaning cartridges in
each LSM. Cleaning cartridges cannot be used as scratch cartridges or initialized by
software utilities.
CAUTION:
READ/WRITE PERFORMANCE DEGRADATION: Do not re-enter a
cleaning cartridge that has been ejected from the library. When you enter
a cleaning cartridge, the software considers it to be new and sets the
usage counter to zero.
When a tape drive/transport requires cleaning, the software selects a cartridge from the
pool of cleaning cartridges in the LSM that contains the tape drive/transport (or from the
closest LSM that has cleaning cartridges). If no cleaning cartridges exist in the ACS, you
are prompted to mount a cleaning cartridge. StorageTek recommends that you have one
cleaning cartridge in the ACS for each drive wall.
When a cleaning cartridge is used a defined number of times, it is automatically ejected
from the library, and you are notified by a console message. Open the specified CAP,
remove the ejected cleaning cartridge, and dispose of it.
Functional Diskettes
If a functional diskette is in the diskette drive when an LMU, LCU, or CU is powered-up,
the program on the diskette is loaded into memory.
If a functional diskette is not in the diskette drive, insert it (see
Diskette" on page
In a dual LMU environment, the functional diskettes in both LMUs should contain the
same level of firmware—Release 2.3 or higher. An error message appears on the console
if different levels of firmware are loaded.

switch remains lit, and the 4-character display shows changing alphanumeric
characters. When the loading process is complete, the IPL indicator turns off,
and the 4-character display becomes blank.
If the loading is unsuccessful, the IPL indicator remains lit, and the 4-character
display shows a hexadecimal error code.
