•
Rewrites—Displays the number of times blocks that had to be rewritten to the device. This
value is maintained since the Tape Hardware Interface driver was loaded.
Rewrite errors may occasionally occur. If this value should rise dramatically, you may need
to clean the device. If you continue to have rewrites, you may have a problem. Some common
causes include radio frequency interference (RFI) on the bus cables, bad or missing terminating
resistors on the drives, or having more than one device with the same SCSI ID. Ensure the bus
cable is free of obstructions and that the devices on the bus are properly configured.
•
Total bytes—Displays the cumulative total number of bytes the tape drive has processed.
•
Tape Drive Heads Need Cleaning—Indicates whether the tape drive need to be cleaned. To
clean the tape heads, insert a cleaning tape into the drive and run through a cleaning cycle.
The following values are valid:
◦ Yes—The tape drive requires a cleaning tape session in order to clean the heads.
◦ No—The tape drive does not require any cleaning tape session.
◦ Not Supported—The tape drive does not support monitoring of the cleaning required
status.
•
Cleaning Tape Needs Replacement—Indicates whether the cleaning tape that is inserted in an
autoloader needs to be replaced because its cleaning capability is exhausted (it is at the end
of the tape). This variable can be in one of the following states:
◦ Yes—The autoloader tape drive requires a new cleaning tape to be inserted.
◦ No—The tape drive does not require a new cleaning tape.
◦ Not Supported—The tape drive does not support monitoring of the cleaning tape
replacement status.
NOTE: This variable is only applicable to autoloader tape drives.
