Description
Enabled
The BlackPearl system processes IOM operations as
needed. If you select this option, the IOM Start Time
and IOM Stop Time fields are unavailable.
Scheduled
IOM processes only run during the period between the
IOM Start Time
and
IOM Stop Time
.
Note:
If you set the start and stop time to the same
value, IOM operations do not run.
Disabled
The BlackPearl system does not perform any IOM
operations.
Notes:
• IOM is enabled by default. Spectra Logic recommends leaving the feature
enabled.
• Automatic tape compaction is configured on a per tape partition basis (see
for more information).
• Data migration is initiated manually. See
for more
information.
• If this option is currently enabled, when the setting is disabled, any in-progress
IOM operations are suspended.
8.
Enter a percentage value for
Partially Verify Last Percentage of Tapes
. This setting
specifies the percentage of the total reported capacity of the tape cartridge scanned by an
automatic or on demand data integrity verification. The system starts the scan at the
specified percentage of the tape capacity before the EOD (End of Data) marker and ends
the scan at the EOD marker. For example, if you specify ten percent, the verification
process scans the last 250 GB of a 2.5 TB LTO-6 tape cartridge, or the last 600 GB of a 6
TB LTO-7 tape cartridge.
• Leave the field blank to configure data integrity verification to scan all data present
on the tape cartridge.
• Percentage values of zero and 100 are not supported.
• See
Data Integrity Verification - Tape Media on page 347
for information about on
demand tape media data integrity verification.
