HP ProLiant DL380 G5 Server - Manual (Page 60)

• Model—Displays a description of the SCSI tape autoloader media changer model as returned by the SCSI
inquiry command.
• Firmware Version—Displays the firmware revision level of the tape autoloader media changer as returned
by the SCSI inquiry command.
• Serial Number—Displays the serial number assigned to the tape autoloader media changer. This value is
based on thee serial number as returned by the SCSI inquiry command.
• Magazine Size—Displays the magazine size of the SCSI tape autoloader media changer.
• Tape Errors—Displays the number of read and write errors that have been encountered with the currently
loaded tape. Over time, a tape device might produce these errors. These errors are usually caused by bad
media sections on the drive. If this value rises dramatically, you might need to clean the device.
NOTE: The number of tape errors is equal to or greater than the combined total for re-reads, re-writes and
uncorrectable errors.
• Re-reads—Displays the number of read errors corrected through tape drive retries. Over time, all drives produce
these errors. If you notice a rapid increase in the value for Recovered Read Errors or Hard Read Errors, a
problem might exist with the drive. The value increases every time the physical drive detects and corrects
another error. If this value rises dramatically, you might need to clean the device.
• Re-writes—Displays the number of write errors corrected through tape drive retries or other drive recovery
mechanisms. Over time, all drives produce these errors.
Having a large number of retry corrected errors does not necessarily indicate that the drive is failing. However,
as a precaution, replace a drive that has an abnormally high amount of errors when compared to similar drives.
If this count increases rapidly, you might need to clean or replace the drive.
• Uncorrectable—Displays the number of read errors that could not be recovered by a tape drive’s ECC
algorithm, retries, or any other recovery mechanism. Over time, a drive might produce these errors. These errors
are usually caused by bad media sections on the tape.
• Tape Drive Heads Need Cleaning—Indicates the tape heads on the drive must be cleaned. If they must be
cleaned, a cleaning tape must be placed in the drive or the autoloader.
NOTE: A value of Not Supported indicates that the tape drive does not support this feature. You might need to
upgrade your firmware to the latest revision.
As routine maintenance, the drive heads should be cleaned according to the recommended schedule for your
specific drive.
• Cleaning Tape Needs Replacement—Indicates the cleaning tape associated with the autoloader is at the end of
the tape. If the cleaning tape is at the end of the tape, a new cleaning tape must be placed in the autoloader.
NOTE: A value of “Not Supported” indicates that the tape drive does not support this feature. You might need
to upgrade your firmware to the latest revision.
• Number of Cleanings Performed—Indicates the number of times that the tape drive has been cleaned. If a tape
drive is cleaned too much it can damage the tape heads.
NOTE: A value of Not Supported indicates that the tape drive does not support this feature.
CD storage system
Select the CD Storage System entry in the SCSI controller submenu to display Library Information and information for
CD-ROM drives associated with the storage system.
CD Library Information
Select the Library Information entry from the CD Storage System list to display the following information:
• Status—Displays the current fault light status of the CD Library. The following values are valid:
• OK—The library is operating normally.
• Failed—Indicates that the CD library fault light is in a failed state. The fault light is activated for hardware
errors (Sense Code 04h) with additional Sense codes—40h-4fh except the parity error. The LED remains
illuminated until it is power cycled.
• Unknown—The state of the library cannot be determined.
