Scan based on Tape
Alert
Choose whether to scan tapes based on Tape Alert count; and, if so, which
type of scan to perform (Quick, Normal, or Full, described above). Select
None to disable this policy. This policy is disabled by default.
When enabled, a tape will be scanned if the number of Tape Alerts
reported for that cartridge exceeds the user-specified value in the Tape
Alert count field, described in more detail below.
The Tape Alerts included in the count are:
• 01h (1)– Read Warning
• 03h (3) – Hard Error
• 04h (4) – Media
• 05h (5) – Read Failure
• 06h (6) – Write Failure
• 12h (18) – Tape Directory Corrupted on Load
• 33h (51) – Tape Directory Invalid on Unload
• 34h (52) – Tape System Area Write Error
• 35h (53) – Tape System Area Read Error
• 37h (55) – Loading Failure
• 3Bh (59) – WORM Medium Integrity Check Failed
Tape Alert count Use this field in conjunction with the Scan based on Tape Alert policy.
From the drop-down list, select the number of Tape Alerts allowed before
a scan is performed.
Normal scan time
interval
Scans a tape if the listed time interval since the last scan was performed has
been exceeded. In the text box, type a time interval (in days) after which a
scan will be performed. A value of zero (default) means the this policy is
disabled.
Note: When deciding the interval, consider the number of tapes to be
scanned in the entire library, as well as the type of scan to be
performed. Full scans can take more than 2 hours on full tapes.
Over-scheduling can cause delays or cause tapes not to be scanned
as intended.
