Virtual TapeServer 6.04.01 Operations and Administration Guide

Using Scan/Cleanup | 99
cleanup_scan_at Specifies when the automated scan and
erasure should run. A typical setting would
be 04:30, which indicates to run at 4:30AM.
To avoid scheduling problems, set this
parameter greater than 00:04 and less than
23:51. Specify 00:00 to disable this feature.
Scheduling this once or twice a day should
be frequent enough to manage disk space
utilization.
Default value: 00:00
Time, in the
24-hour
format;
values
between
(and
including)
00:05 and
23:50 are
allowed
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.
Default value: 0
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.
Default value: 100
Integer
cleanup_nonMigrated Indicates to erase virtual tapes that have
not been migrated. Migration in used to
move data from VTS to permanent storage.
Default value: NO
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.
Default value: NO
YES or NO
