Virtual TapeServer 6.03.41 Operations and Administration Guide

Using Scan/Cleanup | 75
cleanup_interval Controls how often (in hours) the feature
should run. A typical setting would be 24,
which indicates to run once a day. 24 must
be divisible by the specified value; thus, the
following values are supported: 1, 2, 3, 4, 6,
8, 12, and 24. If the cleanup_scan_at
parameter is set to 04:30 and
cleanup_interval is set to 6, Scan/
Cleanup will run at 4:30AM, 10:30AM,
4:30PM and 10:30PM daily. If you specify 0,
the feature is disabled.
Integer
cleanup_threshold_
percent
Enables you to manage low disk space by
indicating the threshold after which a
cleanup is initiated. When the VTS file
system reaches this threshold (a
percentage), virtual tapes can be scheduled
for erasure if this parameter is set. A typical
setting is 90. When 90% of disk space is
used, all virtual tapes on that vault are
scheduled for erasure.
Integer
cleanup_nonMigrated Indicates to erase virtual tapes that have
not been migrated. Migration in used to
move data from VTS to permanent storage.
YES or NO
cleanup_show_erase_
control_files
Displays Scan/Cleanup files that are used to
implement the Scan/Cleanup erasure
process. This is typically set to NO and may
be enabled to help diagnose a system
problem, if indicated.
YES or NO
cleanup_minimum_size_
GB
and
cleanup_minimum_size_
MB
Define which files to ignore based on size.
The values specified by these parameters
are combined to set the minimum file size to
erase. Some installations have many small
virtual tapes and do not require that they be
erased. A typical setting for the
cleanup_minimum_size_GB parameter is
8, which specifies not to erase virtual tapes
whose data is less than 8GB. For smaller
sizes, use the cleanup_minimum_size_MB
parameter only. For example, to set the
limit to 50MB, use
cleanup_minimum_size_MB='50'. If you
specify 0 for these parameters, this feature
is disabled and all files can be erased.
