VOLATTR control statement MAXclean parameter(s). For example, if the
helical cleaning cartridges have volsers between CLN500 and CLN599, the
following VOLATTR statement can be used to set a different maximum
cleaning usage limit for this range of helical cleaning cartridges: VOLATTR
SERial(CLN500-CLN599) MAXclean(nn)
5. Contact your StorageTek Customer Services Engineer for appropriate
MAXclean values for different cleaning media types. Limits on the Use of
Cleaning Cartridges Cleaning cartridges should only be used a limited number
of times. The MNTD MAXclean command globally specifies how many
cleaning operations are allowed before a cleaning cartridge should be removed
from the ACS and replaced (the default is 100 uses). This maximum cleaning
usage limit can be different for different cleaning media. Use the VOLATTR
MAXclean parameter to specify a different maximum cleaning limit for
different cleaning cartridge media.
6. Refer to ‘‘MNTD (Mount/Dismount Options) Command and Control
Statement’’ in the HSC Operator’s Guide and to “Volume Attribute
(VOLATTR) Control Statement” on page 110 for additional information about
the MAXclean value.
7. Ejecting and reentering used cleaning cartridges should be avoided. When a
cartridge is ejected and reentered, its select count is set to zero. The select count
is used to track the number of times a cleaning cartridge has been used. Used
cleaning cartridges which are reentered will be used more times than specified
by the applicable MAXclean value. Each cleaning media type is used in a
different way to clean tape transports. Some media types use the same cleaning
surface many times, while other media types use the cleaning surface only once.
Some media types use the cleaning surface only a few times before they are
unable to clean a tape transport.
When a cleaning cartridge is no longer able to adequately clean a tape transport, it is
over-use.
Over-use (Over-limit and Spent) Cleaning Cartridges
An over-use cleaning cartridge means either that the usage (select) count is over the
MAXclean value (‘‘over-limit’’) or all of its cleaning surface is used or ‘‘spent.’’
•An over-limit cleaning cartridge has been used more than the value (limit) specified
by either the MNTD MAXclean or VOLATTR MAXclean settings. This cleaning
cartridge may not be able to adequately clean a tape transport. If an over-limit
cleaning cartridge is mounted on a tape transport, the cleaning process is attempted
and may succeed.
•A spent cleaning cartridge’s cleaning surface is completely used up or exhausted and
can no longer be used for cleaning. When the HSC detects a spent cleaning cartridge,
it will not be mounted on a transport during automated tape transport cleaning.
Over-use cleaning cartridges should be removed from the LSM and replaced with new
cleaning cartridges. By default, the HSC ejects all over-use cleaning cartridges that it finds
